2001 115hp 2stroke not reaching top end.
20ft 8inch Crestline pontoon 4500rpm feel like it is starved out ..Checked fuel serpator, tank, and lines, Should it max out at 55000rpm or higher??? Whats next.........
thanks

Did it ever reach 5500rpm's? If it didn't then the prop needs to changed to a smaller pitch.
