Hello. There is no water in the cylinders or on the plugs. They are not shiny at all, totally black and carbon fouled as stated. See above for oil filter analysis. The last engine sounded like someone hit it with a hammer one time and then it bogged and shut down. Apparently the intake had been leaking and sucking water enough water to temper the valves for quite some time, although I never saw it on the plugs. I had only had the boat for a little over a year at that point and I do not what the PO's maintenance standards were but I suspect poor.<br /><br />bamadave:<br /> Everything was swapped to the new long block including the risers and manifolds as they were only 2 months old when the engine went. The intake was replaced as it was suspect for the failure and the carb. and alternator were replaced with new.<br /><br />Remember I do not have an outdrive, I have a jet drive. All three bearings and respective seals in it were completely redone in 2004. However, that does not mean there isn't a problem with the drive coupler or flywheel components of the drive. It is not that intense to pull the impeller shaft so I guess I will do that and see what I see / hear what I hear. I have nothing to lose at this point and days before I get the cap and rotor. I will report back on the running minus the drive. Thanks everyone.
