back story engine started knocking.
tore engine apart.
broken piston.
engine is getting rebuilt.
i took the out drive off to get the engine off. do i have to remove the housing from the boat to replace the gimble bearing.
ok thanks Dieter I just figured since I have everything pulled apart I should just replace it. I will check to see if its in good shape.
What is the average price for a new one?
by the way i have a 3.0 mercruiser 130hp
my sons boss has the alignment tool that we can borrow. we bought the boat about a year and a half ago and the previous owner said that he had them replace that spring. how long should the bellows be trusted before replacing them.
That is good to hear. we only have fresh water around us. Michigan.
i have watched videos on changing the bellows. It doesn't look fun at all.
I don't think its terrible if you like wrenching on things. I don't golf so taking stuff apart and fixing it is how I relax...
Lou's advice is good sound just inspect it. I saw some scuff wear on the side of my driveshaft bellows I think from the gimbal ring and I needed to replace my trim sender as well so better to do it during the winter vs during the short summer season. I suspect it will be a 6 pk job...
I'm the same way I like wrenching. Like I said in the first post I'm rebuilding the engine after we get it back from the machine shop. I cant wait to start on that.
Thanks for all the help guys
If you haven't spend some time trying to determine why the piston broke. Do you know if it was related to detonation? If it was make sure you solve that issue otherwise you risk destroying the rebuild.
I'm thinking it was not timed correctly.
me and my son couldn't get the engine to go into base time to set the timing so we left it alone. At idle it would run rough but with some throttle it smoothed out.
I have a new ignition module that we will be using so hopefully we can set the timing correctly.
First - what engine is this ? Yes if you had too much total advance this can also lead to detonation. What did the piston top look like? hard to tell from the photo what the skirt broke due to. Even if you cant get it in base mode you can set it by the total advance at 2800 -3k rpms. You need an advance timing light or timing tape on your balancer to do this. Depending on what year and engine you have you would end up with about 24-30 degrees total. ann
Also be good to look at the plugs see if they look lean.
