Re: price on powerhead rebuild

If you are planning on using the motor after the rebuild, fine.<br /><br />If you are planning on selling it, you are probably better off selling it as is (whole or parts).<br /><br />Is there serious damage to the motor?<br />scoring?<br />broken rings?<br />Or could it just be a bad head gasket?<br />How much do you believe your mechanic?<br />And will he not go over his price estimate?

How did the water get in the cylinder and what are we doing to correct it from happening again?

Re: price on powerhead rebuild

as for how water got in there to begin with, i am not really sure. the only thing i can think of is when my girlfriends father hit bottom(mud). maybe wud or something clogged something temp. and it over heated. (no alarm came on) it was the 1st year i had the boat. ran fine the rest of that year, and started to seem like it was losing power the next year. my mechanic said he thought there was a slight warp to the head. gasket was fine when i pulled it off. he also said i had a warped exhaust plate. now as far as me trusting him? hes a friend of a friend, so who knows. the rebuild will be going to another shop. i will be using this after the rebuild. its an 84 wellcraft hull (CC 180 fisherman) which i love. i put a lot of work into the boat. i just want my engine back the way it was, so i can enjoy it again.<br /><br />i dodnt think there is any serious damage to it. she does run, but a bit rough right now. the shop i will bring it to said 1500 for the rebuild, new pump, impellar, and any extra decking that might be needed and tax of course, he said, just under 1800$

try a new head gasket and exhaust plate cover first. No water flow could be dirty thermostat take that apart first and check.

Re: price on powerhead rebuild

I have seen several of the late model Merc/Forces warp the head in a high-temp situation. Run a compression check, and make sure it's blown before rebuild. Also, (very important), ask the mechanic if the $1800 is a fixed price for repair. A lot of shops quote a rebuild price and then call you back with "uh the crank is shot and you'll need a new one ", or "we found a crack in the block and that's going to run you another $1600", etc. <br /> The late model Force/Mercs are prone to crank and block damage when they go. I end up replacing, or rebuilding, the crank on about 1 out of every three or four that come in. If that shop doesn't stock spare Force parts, it can get expensive.

Re: price on powerhead rebuild

i will ask him if its fixed. i know the compression on the cylander that is getting water is lower than the rest, i just cant remember exactly what my mechaninc said it was. he told me he uses wiseco pistons for the rebuild, which i looked uip and asked around, and got good replies about them. i still wish i knew how it happened. <br /><br />the way the dock is, my boat almost sits on the mud bottom, when its low tide. i wonder if somehow, just after so many times of starting with maybe some mud in the intake made it overheat somehow? im reachin hear, because i always have **** coming out. i just want to be out on the water this year.
