I have a 2001 launch SSV I purchased earlier this year. It has run like a champ since I got it.

I took it out over the 4th of July weekend and had it on the water for 3 days and it ran strong the whole time.

I took it out this last weekend and all of a sudden had no power at full throttle. I noticed that it would not go over 3000 RPM's. I did not see any sensor lights or anything out of the ordinary, other than it seemed to have no power when I tried to pull, or put the throttle down. It started fine, idled well, and I did not notice anything out of the ordinary with engine sound.

the only difference this time out was the grade of gas that I used. I had been using mid grade gas in the engine. This time when I filled up I used a higher grade gas.

Does anyone have any suggestions for the best way to trouble shoot this issue. I am a 1st time boat owner and am not sure where the issue may be.

Any suggestions/ideas/tips would be greatly appreciated!!!!!
