Re: Power drop at high rpm
Sounds like crud in the carb to me. I had a similar problem where my rpm's were dropping from 5300 to 4500. I came home and drained the carbs and saw some debris come out. I ran the boat again and it ran great for a minute than dropped rpm's again. Finally I removed the carbs and cleaned them with carb cleaner and compressed air and it seems to have fixed the problem.
If you suspect it may be your fuel pump, have someone pump the primer bulb while loosing rpm's and see if it makes a difference, but I would almost guarantee its the carbs.
