Mercury optimax 250 jet boat problem
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? |

| 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. --Mike <mczake208@comcast.net> wrote in message |

| Mike ...the problems happen everytime I've had it out. The impeller
is "clean" runs fine and wide open for 1/2 hr then just falls
flat...all most like a vapor lock...which it is not because running
fine for the 1/2 hr. |

| Check the vent system for the fuel tank.

| I gotta agree with JR, it sounds like fuel then. Proper tank venting is a
good place to start. Is this engine EFI or carb? --Mike |
