93 Gamefisher 9.9

[rbutter]

I have a 9.9 Gamefisher that seems to slow down after about 10 sec at full throttle. If you let off and resume to full throttle it is fine for another 10 sec or so. Any ideas???

Weak fuel pump, some sort of blockage in fuel lines, closed vent on tank, bad valve in bulb, clogged filter on tank pickup, float set too low.

Could be any of those. Start with the fuel lines and tank vent.
