I just bought a 1987 Procraft, 19.5' with an Evinrude XP150...carb problems?

Hello all, this is my first post.

So I bought this boat about 3 weeks ago. I've already done some re-wiring on it the motor. Honestly, it needs a new wiring harness. Can you buy them?

Well, here is my most important question. The motor is VERY cold natured....it seems to only be running on 2 or 3 cylinders until it "warms up", then it runs pretty good all day.

It will periodically die when going from Nuetral to forward...but it will pull my 220lb butt out of the water on a slalom ski with 4 adults and a 5 yr old on the boat.

So while debugging, I noticed the middle carbaretor is dripping fuel out of the bottom...and the engine smokes alot until I get it going good.

Compression is about 90Psi on 5 cylinders...I think one was like 85Psi. I have a bunch of questions!

So how hard is it to rebuild the carbs? I'm mechanically inclined (I've replaced clutches on Front wheel drive cars, I do all my own vehicular maintenance, etc...).

Should I de-carb before I rebuild?

Has anyone scanned pages of instructions for rebuilding carbaretors and uploaded them yet?

Are the "Chilton" repair manuals ok?

Are there "boat salvage yards"?

Sorry....I'll take any answers I can get!

Happy boating!

Welcome aboard,

The gurus are looking for a model and serial number so they can help you solve any problem you are having with your engine.

I can suggest that you should buy yourself a good "factory" manual. Click on this link and order yours from Ken Cook, this will be the best that you can get for your engine. http://www.outboardbooks.com/

Compression gauges reading will vary some but yours seem to be on target. I think with a good carb cleaning, a link & sync, new spark plugs, and a new water pump you should be on your way to some happy boating.

If I left anything out them big shot, high fluting gurus will be along shortly and make any needed adjustments to my comments and smack my upside the head if I stirred you wrong.


Good luck,

Yeah...I'm at work, I don't have the serial #...I thought XP150 was the model Number. I was wrong....

I'll get that when I go home in a couple of hours.

The serial # is R1818087
Model # E150STLCCA

Thanks

Will

Looking at the carbs....the gaskets appear new....like they have been rebuilt.

I don't mind rebuilding them, mainly cause I don't know what was done...how good of a job...etc.......I will rebuild them, but would like to avoid if possible. I'd rather pay $75 for someone to "tune" them if that is possible.

One of the bowls is leaking gas as in another post...that originally led me to believe the carbs needed rebuilding.

Now I'm just wondering if I can sand down the plastic a little as stated in another post about my exact same engine.

Dad-gum it. I just wanted to avoid spending big money...I just spent $100 in rebuild kits and an impellar.

I don't mind spending $100...unless I don't need to!!!! That is what I want to avoid. I'm about to spend another $35.00 on a manual....which I know I need....but....$35.00 here and there kicks my butt!!!

The best money you could spend right now would be for a service and owners manual for your engine.

I reluctantly agree

BOAT= Break OUT another Thousand!! http://www.bassboatcentral.com/smileys/wink.gif

Did you order you manuals yet?

I sanded the float bowls on mine, and it's been bone dry ever since. Once you've got the manual, do a decarb and go through the link-n-sync procedures like the wise Dofer Gofer suggested. That's a great motor, and with a little mechanical ability and a factory manual, you can avoid parting with any more of your money than you have to.

Finding this board was the best thing you could have done (getting a factory manual will be the second best)!!

Good luck!

The mods are always here to help!! http://xs-s.com/zf/images/smile/emthup.gif http://www.bassboatcentral.com/smileys/smile.gif

Yes guys, I found the manual!

I sure as heck didn't want to spend the extra money...but knew I'd be foolish not to.

I found it for $35.00 delivered! Can you believe that? I hope this is the good one!


http://cgi.ebay.com/ebaymotors...witem

You lucked up~!! http://xs-s.com/zf/images/smile/emthup.gif

So I got the "best manual"? Or is there a better one?

Thanks by the way!

You got the best. http://xs-s.com/zf/images/smile/emthup.gif

Soooo, how is it coming along?

I sanded mine down, the previous owner/mechanic??? whoever had overtightened them and they were leaking. Make sure after you sand yours down you don't overtighten them http://www.bassboatcentral.com/boardstuff2/beers.gif

Well, my car has broken down..and I'm down to riding my motorcycle. Waiting for till MOnday or Tuesday for the parts to come in for my car.

I'm going to try to work on the boat tonight since I can't work on my car.


on a side note...with no car, my 5 yr old son and I have been having to ride bicycles to his school...which is only about 1 mile away....sort of fun...but ads a few minutes to my morning!

Good morning, and I am sorry to hear about your car putting you down. At any rate, keep us informed about your boat. We didn't advise you to get a manual and then abandon you to repair it all by yourself. We are still here.

Best regards and enjoy the bike rides to school with your son.

I've removed the carbs again...and dad gum it if I didn't drop one of them!!!!

I've re-adjusted the floats. Making sure they are 1" +/- 1/8".

What do you guys think about the damage from dropping the carburetor?

I'm taking it to Rockwall Marine here in a few.

See image below.

Thanks

I reinstalled the rebuilt carburetors....and it started up good. I did a linc and sync, but I did not check timing yet.

I'm scared to go to the lake for fear of still having the problem....but will go tomorrow.

We will be looking forward to hearing on the results or your test drive.

http://www.bassboatcentral.com/smileys/popcorn.gif

runs like crap. top speed about 9mph. I could just cry. so much time wasted.. I just can't figure out whatt I did wrong. it bogs down and dies under throttler

Did you get all the linkages on and all three throttle plates opening fully and at the same time when WOT is applied and is the timer base arm hitting the stop at the same time?

after the linc and sync, did you notice if the timer base arm and the throttle plates advance at the time and rate? here is a bit from my seloc manual:

The fuel and ignition systems MUST be carefully synchronized to achieve maximum performance from the engine. In simple terms, synchronization is timing the carburetion to the ignition. This means, as the throttle is advanced to increase engine rpm, the carburetor and ignition systems are both advanced equally and at the same rate.

hope this helps

All right, don't cry. Things are not bad as they seem. http://www.bassboatcentral.com/smileys/smile.gif Actually right now, it running worse than when you started. Therefore, something is wrong with your repair procedures.

1. The carburetors were rebuilt by a dealer, hopefully they are ok.

Therefore, I am leaning toward "your" link & sync. adjustments and if the recirc valves are plugged or clean and if the recirc tubings are hooked up correctly. Don't forget the timing base linkage must be connected and in sync.

http://www.bassboatcentral.com/smileys/popcorn.gif

This sounds very familiar to me. I think you might find the following thread useful:

http://www.bbcboards.net...age=1

It's a pretty long thread, but there's a lot of information. My motor was basically doing the same thing as yours, and I couldn't pinpoint the problem. It ended up being the fuel scavenging valves (4 of them were completely plugged).

I tried soaking them in alcohol and engine tuner, but I could not get them clean enough to reuse. I believe they were around $10 a piece. However, with them not functioning properly, your "crossflow" fuel system cannot "flow."

There are a couple of barbs that go into the intake manifold, and I drilled those slightly oversized to help the fuel system breath a little easier. In order to do this without getting shavings in the intake manifold, I smeared a drill bit with grease, and the shavings stuck in the grease (go really slow).

This really sounds like the same problem I was having, and you've already done a great job of ruling out some things. The manual you purchased shows a very good hose diagram for the recirc hose system.

http://www.bassboatcentral.com/smileys/eek.gif http://www.bassboatcentral.com/smileys/eek.gif BIG WARNING http://www.bassboatcentral.com/smileys/eek.gif http://www.bassboatcentral.com/smileys/eek.gif : The little plastic barbs (tees) in the fuel recirc hoses are very easy to damage, and they don't like to come off by pulling. I would recommend buying some replacement hose, and just cutting it off the barbs. If you try to squeeze, pull, or twist the hose, you're likely to damage the little tees. You can also buy some of the plastic tees for not much $$$.

Good luck!!

Thanks for you guys' help. I'm just upset because I had a boat that was running...though not great, it would pull me skiing and what not. Now after I rebuilt the carburetors, it won't go more than 9mph or so.

I've already pulled the carbs off a 2nd time...and i just can't see anything wrong with my rebuild job!

I'm going to look more into the things you guys have pointed out. I just hate that after 12 hours or more of labor, and over $100 in parts...I now have boat that is good for floating!!!!

Very frustrating.

William, try to keep this in perspective. The moderators on this forum have spent years receiving factory and on-the-job training to have the level of knowledge and understanding that they bring to us DIY guys.

http://www.bassboatcentral.com/smileys/mad.gif You've expressed frustration on pretty much every response you've made on this thread. Trial and error is truely part of the process for those of us that haven't chosen to make a career of this. If this is a sticking point for you, your time may be better spent researching your options for a Factory Authorized Bombardier Service Provider with good references.

I think it boils down to what gives you the best value. I would suggest you contact a factory authorized Bombardier service provider, and request an estimate on the cost for them to perform this work, including an estimate on how quickly they could get it done.

Once you've got an idea of what it would cost you to not have to deal with it yourself, try to put a monetary value on your time and frustration (plus parts). If the cost of parts and service received from a shop is equal to or less than the cost of your time, frustration, and parts required, than taking it to a shop is a better value for you.

I really enjoy working on my motor, and the guys on this board are kind enough to share their experiences and expertise to help me avoid some of the major setbacks I would inevitably suffer if I just did it all on my own.

If you decide to do it yourself, this board is your best resource. It will certainly require more of your time, but you will save money in the long run. http://xs-s.com/zf/images/smile/emthup.gif http://xs-s.com/zf/images/smile/emthup.gif http://xs-s.com/zf/images/smile/emthup.gif

Keep your head up!! http://www.bassboatcentral.com/smileys/wink.gif

Time and money are too things I can never get enough of.

I guess it is just frustrating knowing Summer is almost over, and if this keeps up, I will not get to ski or play until next summer.

Well, for now, I have removed the carburetors for the 3rd time. I will pay someone to check my work if I have to. I've gotten quotes of basically $150 per carb for a rebuild...which seems extremely high for the 3 carbs ($450).

I don't want to pay someone $450 to do the same thing I did, then tell me I need to spend another $400. for another problem. That would be catastrophic for me.

Also...I do enjoy working on engines...one of the reasons I'm doing this is to learn. But the boat was running ok until I rebuilt the carbs...so I KNOW the carb(s) have some sort of issue. You can tell one are more are flooding out!

A funny hind-sight...It dawned on me today...I bet the reason the boat running was getting worse was due to the fact that the primer pump...or whatever that black bulb that you pump gas with was stopped up....I didn't discover this until after I rebuilt the carbs.

Thanks for everyone's support! I really do appreciate it.

Tell you what I'll do, I have a 86 GT150 on the rack, I'll pull the carbs and rebuild them myself this week and ship them to you. They will be right all you have to do is mount them and send me back your carbs once you mount them and are happy. The bowls on the 86 are metal as opposed to the plastic but that won't affect a thing.

ChampioNman...send me your address...I'm buying you some beer!!! http://www.bassboatcentral.com/boardstuff2/beers.gif
Way to go!!!

The same carbs except metal bowls vs. plastic?

I truly don't know what to say. Did you see the picture where I dropped the one carb? Let me know if you need more pictures. I kindof smoothed it out...the guy at Bunting Marine here in Wylie, Texas said it would run like that...but if you disagree...I understand.

And believe me...I'll pay you some cash. I have paypal. check, cash, whatever...LOL.

Take CampioNman up on his offer. When you get the cabs you KNOW they will be right. One less thing to worry about.

believe me...I am!!!

I'd be a fool not to. I'm no fool.

And maybe he can tell me where I screwed up!

Shoot me an e-mail with your address, my e-mail is in my profile. Gonna get on them this evening. http://www.bassboatcentral.com/smileys/wink.gif

That's just one of the reasons I call this man my bud!!! I see him making offers like this all the time. http://xs-s.com/zf/images/smile/emthup.gif http://www.bassboatcentral.com/smileys/bows.gif You da man Fred!!

You guys on here are great. Sorry to hear your having troubles w/your carbs. The info I got was great and all is well after I took it in for a link and sync.

I will send anyone I know to ChampioNman for repairs!!!!!

Did I miss something? Did you set the idle timing when you did the sync and link? Did you check the carbs for wide open throttle? Do this with the shift and throttle handle at the control box, also do all sync and link using this handle. Do you have any questions about the sync and link? There is so much slop in the linkage on these motors that it's very easy to get it wrong.
