Motor is toast....I need alot of advice here....

[esoxfly]

On plane tonight at 5k, motor sounded like it revved, then I lost power all in a second or two. Checked the tach and it was down to 4k, then down to 3700. Off plane, motor sounded bad....running but rattling. Soon after, like maybe four seconds after it happened, it died. Tried to restart (yes took it out of gear) and just a heavy "thud" when you hear the starter engage. It's enough of a "thud" to feel it in the hull when standing in my garage.

Got towed in (thank God for towing insurrance), and pulled the cowling when I got home, and there's no outward sign of damage. No leaks, no tell-tale signs.

But, my remote reservoir has barely dropped level in the last two days. Main reservoir is full. Could my oil injection have failed? I'm thinking lean seizure, or I just outright lost a rod or a crank or whatever.

This is my first dead motor. What does this sound like to y'all? Something simple I'm just missing? I mean, this motor is toast right?

I think I want to repower. I literally love this boat as much as anytihng in my life, and honestly want to keep it until I'm old and grey. So a rebuild is still "just" a rebuild, and a repower is warrantee and a new lease on life. What's the best way to do that? boats.net sells 225 HPDI's for $14k...do people buy complete motors online? What's the best way to get rid of the old motor? Part it out, or is there someone/somewhere that'll buy shot motors and take them off your hands...other than a junk yard.

Alot of questions here, but I need all the info and advice y'all can give. I'm not the first dude to go through this, but it's the first time for me. So I need some help here.

I would bring that motor to Hydro Tec and let them work there magic on it. I think that they do give a warranty on they rebuilds. They can also put some more HP in that motor and it will be a lot cheaper then a new 14k motor.

By the way it sounds like a seized piston. I would think that a rod would have come out the side of the motor at 5000 rpms.

Give the H/T boys a call and see what they can do for ya.

I agree with Connor.

First time for everything...

[rangerguy]

Have you pulled the oil plug on the lower unit gear case. I have had lower unit go out and make the same sound as you have described. Just a suggestion.

[esoxfly]

Haven't really touched it yet. I want to take it to work tonight and scope the cylinders and see if I can see what happened.

Haven't checked the l/u. I'm far from an expert, but how would that cause this? (I'm asking because I don't know...not to doubt you; I'm open to any suggestions.) I've heard of guys that have had a noise from a "dry" l/u, but the powerhead is locked up and the prop spins freely. And in the few seconds it happened, the sound was pretty evidently coming from the powerhead before it died.

[rangerguy]

As I said just a suggestion, if you have made up your mind, then go with what you think. Good Luck and hope it is not as bad as you think.

[esoxfly]

Thanks, and like I say, I'm open to any and all advice and suggestions. But this motor is in bad shape. It won't even turn over, the oil reservoir looks like it hasn't gone down a bit in the last two days, the motor died on it's own....I'm just thinking in my head it sounds like a seizure. I'll get it looked at this week and see what I can find for sure.

I know this is most people say go 2 stroke on this board but with your hull I would consider a 4 stroke yamaha. I have a 250 yamaha 4 stroke on a bay boat and it does better with hole shot than I would have thought. Much less chance of a powerhead loss. I also have a series 2 225 hpdi that so far so good but this is on a bass hull. I personally think the days of the 2 strokes are numbered.

Pull your motor cover and see if you can spin the flywheel by hand and in neutral. If not you could have had a rod bearing seize on the crank. A split in a water cooling passage is a death knell for motors. Only way to tell is to tear it down. There are many places that provide both long and short block re manufactured power heads. You generally need to supply them with a usable core.

[esoxfly]

What does that run? The sucker is locked up. I won't have a chance to look at it until tomorrow evening, but it's locked. The more I think about it, the more I'm thinking it's a lean seizure. Either on the cylinder or on the crank. So yeah, it'd be a total rebuild...and that would run, what?.......$6,000?

Yeah, I saw that. I might get flamed for this, and I know alot of guys have boats previously owned by tx anglers, but buying my boat last year, the one piece of advice I got most often was to not buy a boat/motor that had been consistently tourney fished.

That price is right, but the warrantee is expired and I'd be on my own, and basically where I'm at right now if I were to just rebuild mine...with a motor that's probably just fine, but with no support or safety net should it go again.

I'm sure it's a fine motor, and it's not out of the question, but going through right now what I am- catastrophic failure on a motor that costs more to rebuild than it's worth....I'm a bit leery of used motors.

Take it to hydrotec. I did and was really happy with the rebuild, warranty, price and new found performance!

[esoxfly]

And that was?....... Price? Warantee? And how's that work? I take my boat to them, or they send the parts to me or a local dealer and we do it here?

[ChampioNman]

You pull your head off and ship it to them. Check out the site. Here is one.

Well it's not seized! I went out and found the starter still engaged, which I thought could be it, but today was the first time I've had ten minutes to look at it. BUT! It's still toast. It'll turn maybe a revolution, and then lock up. You can feel crap in there grinding around and it just LOCKS up. There's no pushing it through a rough spot or anything like that, you hear metal to metal contact and the motor is locked. After I free it from the starter and try to crank it, same thing, turns maybe revolution and then locks up and hangs the starter like it was when I found it. Either way, I figure it's toast. Going to try to scope it tomorrow.

[ChampioNman]

If you pull the heads off that may show you if it was a piston or ring failure. If you pull the spark plugs you may see metal on one or a smashed electrode. Anything else the head will need to be pulled off and a tear down is in order.

[esoxfly]

Yeah, I'm gonna start digging tonight.
