I've been helping a friend of mine recently with his boat. We had a
bad VRO pump and decided to mix the oil rather han letting the VRO do
it so we bypassed it. The engine seems fine out of the water and
perfect when in neutral, but when in gear in the water will not rev
above 2800 rpm's. I am wondering if we missed bypassing a sensor or
something else when we eliminated the VRO.
