Force 85 ph problem

[hotdogman]

I have a 1990 85 hp Force engine with a busted<br />piston. How can I determine wether to rebuild<br />it or buy another one? Also is it difficult to<br />bore and rebuild? <br />I know the cost of parts and labor form someone<br />is about 3500. <br />Any suggestions.

Re: Force 85 ph problem

Have you actually looked inside the engine yet?<br />Busted piston ? Specifically, what does that mean?<br />Low compression on one cylinder?<br />Blown head gasket?<br />Did it overheat?<br />Actually a hole in the piston?<br />Broken ring?<br />Have you examined the head for damage?<br />Water in the cylinders?<br /><br />Some rebuilds require more than others depending on the damage. I've seen them cost from $900-$2500, but not $3500 for a motor like that one.<br /><br />Did a shop give you that price?<br />Likely they bid the worst case senario and then added an extra 50% as a deterrant to you.<br /><br />Would I put $2000+ into that motor, even if it truely required a major rebuild? No way. Better to look for a decent used motor for $2000.<br /><br />You should be able to get all the parts for around $900, then add the cost to have the head milled, cylinders bored and honed.<br />Probably gonna cost you $1500 even if you do most of the work yourself, and don't run into any problems, and you don't need any ignition parts..

Thanks for the reply. I have looked inside,<br />and the piston is bad. Cylinder walls are scorn.<br />Low compression, oh yeah. 1 and 2 are loose also. I bought the thing like this, you know<br />a pig in a poke. <br />I guess sometimes the bear gets me.<br />#3 Broken ring, ripped out, and <br />disintergrated out the exhaust port. A little <br />banged up there too. That's the piston that's bad. I can do all the work,<br />and have a machine shop. I am not sure about water in the cylinders. <br />I just don't want to waste alot of time on it,<br />and it not be worth it.<br />And if I buy another motor, not sure about it's problems?<br />Everything else on it seems fine.<br />Do you know what kind of time I am looking at<br />putting in on this?

Howdy, Hotdogman.<br /><br />Welcome to iboats. <br /><br />Why would you post this in the Non-repair forum?<br /><br />I will move it to Force troubles for you.<br /><br />Good luck.
