I have a 2009 25' JC tritoon, that is not running at full MPH. The motor is tunning 5200RPM's, but it only running 22MPH's, & that was with a GPS.
I have had it in the shop for a running issue once before, & they said it was a fuel filter. From what I can tell its almost like it is running im limp mode.

I would like try to fix this this weekend with out pulling it out of the water to take it back home.

Any help would be greatly appreciated.

Thank You

Might try replacing fuel filters and spark plugs to see if helps.
