Hello all. my name is Marc. Ive been lurking here for months and wanted to thank you for all the great info this site has to offer to boaters like myself
i just finished my tear down yesterday thanks to swicks great video........
ill start with the history of my boat.
I bought a 1990 bayliner capri 18 foot that came with a 1990 90hp force outboard (model# 906x90c and serial# 022573). When i bought it the guy told me that he could only get the engine started with the choke on, and couldn't get it to stay running without the choke on..
I brought it to a well know marina shop here in town and got them to do a carb kit and clean and adjust everything. Boat ran very very well after that. i was hitting 34mph with two people in it. Then i started getting starter probs.. bought a new starter and i was back in business. This past weekend i go on the water with my son and let him drive a bit. As hes driving full pin, the engine suddenly made a weird sound and lost half power.( what i mean is that even with the throttle wide open i couldn't even get 5mph.
i bring the boat back home and start searching the site for answers. i fall on Swicks issue and i headed back outside to check my engine. Compression on both first and second piston was 144 and 0 on the third . Wouldn't you know it, i too have a bad piston in the lower cylinder.
As mentioned above, i tore the sucker apart to see if there was more damage. From what ive seen so far im lucky because the cylinder walls are not that badly scratched and i might get away with honing.
Before i bring it in to the machine shop i was wondering if you can help me with a few issues i have and look at some pics i took.
1- when looking around i noticed a chunk of the water sleeve missing at the edge of the middle cylinder . Is this bad??(see pics) Can i fix this with something?
2- When i removed the piston shaft caps i noticed that the needle bearings didnt stay in there cages like Swicks did in his video....is this normal??(all three were like that)
3-how can i tell if this has been bored? (what do i look for)
I think thats it for now friends...im sure ill have more after work to ask....Thanks again in advance for all your help.
i will post pics in next post
