Boat description:
Year:1989
Thundercraft 17feets
Motor: Evinrude 60hp 3 cylinders
VRO: bypassed (mixed manually on the tank)
Problem:
Acceleration.
I push the accelerator to the bottom and the boat does not get up and plane. It moves like a half speed.
Sometimes by itself without touch anything it starts to accelerated full speed, get up and planes very nicely.
What I have done so far:
I already have changed the gas, using a small portable gas tank with brand new fuel line and new gas mixed.
I have opened the front of the carburetors and drained all gas.
I have tuned and adjusted carburetors needles and the accelerator cable.
Please any idea what could be the problem? Why the boat/motor is not going full speed and some times by itself starts to accelerate go full speed and is planning beautifully?
