1994 evinrude 150 intruder low water pick up?

[stratos 284 dc]

1994 Evinrude 150 intruder GLERA Serial#g03618278

On a 1994 Stratos 284 dc

I just bought a CMC PL-65 jackplate for my boat. My pad height was like 8.5"

without plate installed. Haven't installed yet. I was told to set it to 4.5" an go up

from there. My question is will i need a low water pickup? Is this something i can

do myself? Do i have to go to dealership to do? If it is something i can do, I have

solid skills. Is there a kit thats better than others? I looked online and can't find

much? Do I have to get a new lower unit? Any info would help

Thanks

Doug

[stratos 284 dc]

I have water pressure gauge 23 psi at wot at 8.5" below pad

[hulapopr]

shouldn't need low water pick up,you will probably find the best performance in the
3-31/4 inch range below the pad,water pressure should not be a problem.

[stratos 284 dc]

thanks hulapopr

anyone else?

[Lockjaw]

I am 3 inches below with no water pressure issues. Do you have the 4 holes on each side inlets, or the one with the little black plastic screen? I think the 4 holes ones are more sensitive to height, but you can always block off the top one on each side.

Mine has the black screens.

[stratos 284 dc]

Mine has the black screens

How fast is your boat

mine goes 57.6mph with out jackplate on yet and pad height at 8.5"
raker2 14 1/2 24p
motor only revs to 4900
need lift hope jackplate does it

[Lockjaw]

Mine has run 63.3 gps loaded for a tourney with a partner. When I got it, I didn't have a jackplate, and the motor was low, and would only pull a 25p gade to 4800. The speedo and GPS seem to agree, I have gotten as much as 66 to 67 out of it on the speedo, so I feel certain it will get there GPS light with just me.

You need to get a jackplate and raise the engine, it should pick up. The only time I ran a raker (24p) I could spin it 5400 rpms, but that was before I went to the bigger carbs.

I am 3 inches below now. I am currently running a 25P TR04, which I can turn 5200. I believe it is a stiff 25, most of what I have seen says those props act like one with an inch more pitch. I got a 24p one on the way. I hope I can turn it a little higher.

My engine is on a 6 inch plate with 1 inch spacers, and it is at the top of the jacks travel. Next mod is boyesen reeds and ficht reed cages.

Start at 3.5 inches below the pad, and go up until you have trouble picking the nose up or lose water pressure. Make sure you have it turning, that is where I have run into problems in the past. I can run straight fine, turn and the pressure goes away. If you take a passenger, that will help. I have found I can usually run 1/2 to 1/4 inch higher without a passenger then with.

I would like to go to an 8 or 9.5 inch rapid jack. Mine comes out of the hole pretty well, I don't think I need the hydraulic, it just makes the adjusting easier. Get the skid plate for the bottom of your jack too. I made one for mine with some angle iron aluminum, some stainless screws and a thin flat piece of aluminum I got from HD or Lowe's.

You don't need to rev the snot out of the engine either. It makes peak power at 5400 and it drops off fast after that. Shoot for that loaded when its warm and you should be good all the time.

So lets chat for a minute

My boat loaded never ran empty 57.8 gps like I said 8.5 in below pad turns like 4900 rpm. The motor is set at highest hole. At wot full trim the nose seems to far down. The spray from the sides of my boat comes out like just a hair behind where im sitting. Raker2 14 1/2 24p. So I bought cmc jackplate. My holeshot is fast faster then any boat in my club. Now my impression of what i want to do with the jackplate is Set the jackplate at 4" trim down, take off, then full trim, then raise the jackplate up. Is this right? The jackplate should give me more bow lift and hopefully more speed. I just got as a "If I hit shit prop" a 14 1/4 tempest 23p
from someone from my club for free NEW!! Im going to switch the hub. How do you think that would do. Im going to run the raker2 first with jackplate, just need ice to melt. Whats the purpose of skid plate? block water, the jackplate arrives tomorrow so havent seen it yet. Seen plenty just trying to imagine skid plate. Any idea about how much speed i can expect? Or change in handeling? Im thinkin 2-3 mph. Just because my pad height is so deep now and no lift, plus want to turn 5400rpm.

Now i interested in nowing about you motor I was into cars and building engines for years before bass fishing im only 28, I think iv'e put parts on everything i have owned. you talked about carb swap is there any thing I can do for my motor? The reeds iv'e already looked into and am all about it, worked on snowmobiles but never boat motors, You rejet after reeds? What are these ficht cages? Are shaving the heads a no no. I know my boat will never be the fastest but want to make it fun for me and as fast as it could be.

[ChampioNman]

This may be a dumb question but how are you measuring your pad to motor relationship? 8.5" below pad seems mighty deep for a 20" shaft motor. Especially if you are on the highest mounting hole. Or in our terms that would be the very bottom hole.

[Lockjaw]

I would expect your boat to run similarily to mine. You might like the Tempest better, it has alot of lift, and it was a recommended prop for my boat too.

Let's start with an accurate prop to pad measurement. Get a level, and lower the front of the trailer until you can put the level in the very middle of the hull, right at the back of the boat, and it shows the boat sitting level.

Then adjust the trim on the outboard, with the level sitting on the cavition plate of the lower unit, and get that level.

Then measure from the floor to the middle of the pad, right at the back of the boat. Write that number down. Then measure from the floor to the middle of the prop shaft, and write that number down.

Subtract the measurement of the middle of the prop shaft from the measurement of the pad, and that should be how far below you are.

You are jumping out of the hole because you have no jack and the motor is probably sitting a little deep.

Mod's for an intruder are not plentiful. I am changing my reed cages to ones from a Ficht 150, and I am going to run a set of boyesens. I have someone that says he is going to make me a set of carbon fiber ones to try, so then I can compare them. That is pretty much it, your engine should have the big carbs. You can run more compression, by getting a set of heads from Monty Racing, but then you have to run either super unleaded or mid grade.

Sam Baker told me he is working on reviving their hot heads for this engine, and those add about 12 hp, without increasing comression. I will likely wait for him on that mod. I should have my reeds sometime next week, so I will probably swap out reeds and cages next weekend. If my other prop makes it, then I will take it out with me and see what happens with it. I will report in the results. I would like to see how it does as is, with the same prop I have been running, and then when I swap out the prop to a 24p version.

The skid plate for the jack helps when you take off. That is really it. It helps keep water from hitting the motor side of the jack plate when you take off.

I think what you will find is adding the jack and raising the engine will get you where you want to be. You may want to run some seafoam through the engine by adding it to your gas, just to make sure the motor isn't all carboned up.

When I got my boat, I had a problem with the speedo pick up flipping up, so I had a hard time getting good speed readings from the speedo. I feel like the best it would have done with no jack and the gade was about 60, if not a little less. I was only turning 4800, so I was right about where you are. Raising the engine allowed me to turn the raker to 5400, but I never ran it before the jack installation. I had a hard time with ventilation with the raker too.

I have to trim mine all the way up. I asked about that on the Javelin/Stratos board and was told that is fairly normal. I think if I moved the engine back a little more, it would balance the boat a little better and allow me to use a little less trim. I just haven't really done much about messing with that.

[stratos 284 dc]

I cant check pad height right now my lower unit is off motor
Did it last year the way you guys describe. I want to say it was 8.5" i may be wrong but I remember it was way deeper than anyone recommended at least 6.5"

I have a nordskog digital speed gps tach gauge in dash so i now my speed and rpm is correct

Just opened jackplate box going to install this weekend then have to go out of town for work all next week

Hopefully run boat next weekend Will post results Thanks for all the advice let me now how you boat does.

Thanks again

[Lockjaw]

Just be sure to silcon up the bolt holes before you install the plate.

And just so you know, my motor was fairly low too. When I put the plate on, I made a mistake in my measurements, and had the motor way to low, and couldn't figure out why I wasn't gaining any rpms. Since I was fishing a tourney, there wasn't to much I could do, so I raised it about an inch. I should have raised it about 3. I was 5.5 below when I got home and measured it.

Post your results. I bet you see mid 60's or so once you get it set where you like it.

[stratos 284 dc]

So I just ran the boat an am sort of disapointed Had all my tackle about 80lbs worth and almost half tank of gas

With the jack plate all the way down my pad height is 6.5in that is as high as i could set it with motor all the way up and jackplate set as high as it could go. Now not that big of deal because i get 5.5" lift from the jackplate.

So measured my pad height before installing the jackplate and it was 8.5" below pad

I know Im measuring correct.

So I ran the boat started out with jackplate all the way down so 6.5" below pad holeshot is great always was though

Before the plate i would get what i would call some blow out at around 25mph to 32mph through my trim cycle boat would heistate for a second then bite an go

That is now gone i trimmed all the way up ran boat to wot 55.6mph 4900rpm 28psi water pressure

Then raised the plate while still at wot to 3.5" below pad 58.6mph 5100rpm 24psi water pressure

Went higher to around 2" and started to lose water pressure a little and boat started to slow down.

With the jackplate down at wot and then lifting the jackplate I could feel the bow lift so Im happy with that seem to get more boat out of the water

Just not what i thought would happin. i think i have to much prop The 14 1/2 24p raker2 won't let me rev it out

I have that 14 1/4 23p tempest I have to pick up from getting the hub switched out

I going to try that i dont know what else to do to get the rpm up. Boat ran nice i like the jackplate if i could get 63mph I would be happy because it is only a 150.

[hulapopr]

it should turn the 24 raker,my 96 intruder on a 295 pro would turn 5600 easy and gpsd at 66.4 25 gal gas an me 230 and 50lb tackle..are you sure you don't have a problem with the motor causing it to be low on hp.

[stratos 284 dc]

So I just ran my boat with the 14 1/4 23p tempest an am now really confused

First of all the vent plugs have been removed so i get a lot of slippage at take off
not worried about that right now just replug them

After that the boat runs the same 58.9 mph 5100 rpm

I dont see how that is possibe I checked my throttle linkage to make sure its getting wide open throttle

What would be keeping my motor from reving up to 5500

The motor runs great

The only thing I can think of is last year when i bought it
I ran the boat an had the upper bolts the connect the motor to the tilt/trim snap off
bend my shift linkage and the power head was shifted forward like 2 in. Upon looking further one bolt was all that was holding for awhile for who owned it before because one was a fresh break the other was rusty.

I looked at my "drive shaft" don't no what else to call it seems straight and fine but if it was bent could that effect it?

Any ideas would be great

Im lost I know It will only go so fast but I would like it to run as good as it could

I dont want to have to take it to a shop but w.t.f

</TD></TR></TABLE> WTF? You've changed the story in mid stream. You need to replace the upper mounts and bolts with the Ficht uppers (one good thing about them) and the same with the lower mounts.

[stratos 284 dc]

ChampioNman

Thank you for responding

So you really think that mounts could be my problem?

The Ficht upper and lower mounts i would need to get what year motor do i order the mount for?

Is it a 150? My tool skills are great but my outboard motor knowlege is weak

[ChampioNman]

Order the Ficht motor mounts and you will be a happy camper. That is one of the best things OMC did.

[stratos 284 dc]

So my mounts are broken or messed up do to the bolt snapping and are now limiting my rpm?

Do I just get upper and lower mounts for a like 1998 evinrude ficht 150 and install them
