Thanks; I do have the 99 PWC Sea Doo Shop Manual and it covers the 787 engine in detail. I plan to overhaul the carbs this winter. James

An update on the winter project. I did procure the jetboat manual. I have finished repairing the leaking tuned exhausts and will install them shortly. In the throttle assembly the port throttle stick easily drifted back after being advanced. I removed the assembly and tensioned it. The front convienience light (footwell in the open bow) does not work. Light is ok -no power. Anyone have to repair the wiring harness to that light fixture? Otherwise I believe I will leave the port carbs alone and fire it up in the spring and see how it runs. James

I should have included this in the original posting. The tachometer is a close tolerance fit in the instrument panel opening. Make sure when you replace the flap that it and the glue holding it do not protrude very much from the surrounding cylinder. In addition, one thing I thought about but forgot in my repair. It seems since the tall transistor vibrated loose, one could place a dab of RTV silicone or Hi Tack between the transistor and the silver cylinder behind it. That would effectivly keep in in place.

While I don't know the specific carb model and setting for your boat it might be worth downloading the shop manual, http://seadoosportbo...00-shop-manual/. The manual might provide this information you are looking for.
