2004 Tohatsu 30

[Tanner38Clark]

I have a 2004 30 Tohatsu that has a problem I can’t seem to identify. The motor runs good for about 10-15 minutes then it starts bogging down and will only run at an idle. If I give it anymore throttle it will bog down and cut off. The carbs have been cleaned, water pump replaced, and new spark plugs. What could be the problem?

The fuel line and fuel tank are fine. What could be the fuel delivery problem?

Pump issue possibly, or carb float valve/seat.

When it starts bogging is the primer bulb maintaining some pressure?

Also verify your fuel tank vent is open/working.

Is it and MFS30A or B? Year is irrelevant.
