ok, I've got a 1990 thundercraft runabout with a mercury M90 oil injected engine on it. It was a 100% working boat when I bought it and had no problems with it several times taking it out until one day my bilge pump crapped out on me in rough water and the boat went down lol. (salt water)
It was under about 15 minutes before a parasailing boat hooked on to it and pulled it up and we got it floating again. I got it home and emptied everything. There was 3 cups of water in the starter alone lol. Anyway, we drained the gas tank and the fuel bowls as well and put fresh gas in and got it running again and it has been cranked and run regularly the past year while I've gotten other projects done until I could get back on this one.
We even took it out again last year and it did pretty good overall. Well, now I've got some setting up problems I need to fix.
How do I go about finding out the exact model number of the engine so I can start parts hunting for it?? I can get the serial number later if needed for identification but cant find an exact model number anywhere on the engine??
I want to get the correct repair manual, etc for this engine so I'm pretty sure that is definitely needed.
I know at minimum I need to replace the water pump. I also have a little diode on the right side of the engine that smokes when the engine is running (cant be good). The steering is locked up and I think while we were trying to free it up that I may have damaged the steering cables so I'll be probably needing replacements. Also, whenever we put it in gear, the choke lever goes up as well and we cant find any frozen linkage on the engine itself so I'm thinking either the control box is the problem or the cable is the problem.
I'm going to completely rewire the boat anyway so that's not too much of an issue.
When I get home tonight I'll get whatever numbers you guys need if you tell me about where they are located. I'll also take a pic of the diode thing I'm talking about for identification purposes so I can get that replaced as well.
