The sieral # is 4265448 which is what I found was a 1975. It started off losing fire on all cylinders then regained it for a couple trips on the water. After the second time it lost fire I jumped the gun and bought a new coil not thinking to run any tests to see what the problem was (I know...
This has been a great motor since my Grandad bought it new. The problem I am having with it is when it is at a idel it pumps water fine. At full throttle it doesn't. I checked the impeller and it is fine, the keeper that holds the impeller in place is still there. The head gasket was leaking...
I am not getting any fire out of my coil on this motor. I replaced the coil today and it fired a couple times then nothing. I hope it isn't something burning the coils up since it was $120 :rolleyes: Any ideas on what I should look in to next?

I have the motor out of my 87 Sea Ray Seville 19' CC. It is a 4.3 merc. When I removed the motor the leg bolts holding the motor mount down weren't holding well. I am guessing that whatever is inside the mounts that are fiberglass on the outside is rotten. Is there anything I can fill the mounts...
I have a 87 4.3 that has a hole in the #6 piston. The guy I got the boat from had the same happen but I'm not sure what piston it was. The spark plug was broke and the valves looked to have been beaten by what I am guessing was part of the spark plug. I was thinking of just rebuilding the #6...
