First of all, this forum has been a great help to me in my SeaDoo PWC and boating ownership. Thank you for that. I'm looking for some help now with an engine problem.
I have a 99 Sportster 1800 with twin 717s. I cleaned and rebuilt both carbs this spring and had a great time with it so far. Saturday, we were on the lake, running at about 5500RPM, and the right (starboard) engine shut down. I tried to start it and it just clicked. Uh Oh was my first thought. We limped back to the dock on the Port engine. Out of the water, I tried to start it again and it turned over, but made a bad grinding noise. The other engine still cranks right up with no issues.
I travelled on business this week, so I just got back to it this evening. Both cylinders read 140 psi compression, which I think is good. It still has the grinding noise. I can rotate the flywheel counter-clockwise by hand, but hear a click about every 10-20 degrees when I do. It won't rotate clockwise by hand.
Tomorrow, I'm planning to pull the pump and see if that is the problem. I changed the pump oil in both jet pumps this spring, and had the inner seal replaced on both.
Questions: Could it be a bearing or something on the crankshaft? If so, how bad is that?? If I sucked something into the pump, where would the damage usually be seen?? Any other suggestions based on these symptoms??
