Boat stalling when going from idle to WOT

[CameronMoomba]

Hi everyone,

I have a 2006 Moomba Outback V Drive, when i go from idle to WOT the boat stalls or idle to drive then WOT it stalls.

also it stutters a lot as when i engage drive, after it get through the stutter it runs perfect, if i roll on the throttle I have no issue.

I'm thinking maybe accelerator pump?

Has anyone else experienced this?

Thanks

Cameron

I have replaced throttle position sensor.
$35 chevy suburban 5.7L 1999 or so year if you have throttle body.
My symptom was black (rich) exhaust and high idle at neutral as well as hesitation and dtall.
2004 supra indmar 325.

Is it a Carbed boat? If so thats a classic accelerator pump issue. You can see if it's working by removing the air filter, then pump the throttle, should see a big squirt of fuel.

It is a Carbed boat, I replaced the accelerator pump and still have the issue.

Is your Supra 22 Carbed? Mine is not sure if that makes a difference
