Sounds like a major problem on a boat that has only 30 hrs on the engine.
Does this happen every time you go out, or just the last time? I know you
said it always had this problem, but for all I know you only took the boat
out once. Anyway, check for crap wound around the impeller.

I have a Polaris jetboat with a optimax 250hp engine, after running
fine for 1/2 hrs. The boat fells as if its running out of fuel, the
engine surges and will not go past 10 knots. I've checked all fuel
lines and filters...ok. I just bought the boat it has 30 hrs and has
always had this problem. Does anyone have any ideals?
