G'day, a mate has fitted a 55lb Haswing Cayman trolling motor to his Quintrex 400 widebody with a bow mount. Fitted with the shaft dead centre of the bow, but boat refuses to track straight. The motor is not veering or doing anything untoward, but boat veers to one side or the other, then it takes a large adjustment before there is any effect, but this then becomes an overcorrection. The result of this is constant zig zagging and an inability to both fish and steer at the same time, it's one or the other as while you flick out a cast, the boat will start heading for the bank. Everything else on the boat is spot on, but this has us tearing our hair out. It appears to me that the quite sharp centre keel at the bow is being acted on by the thrust from the prop - Point the motor left to go left and the prop thrust pushes the bow to the right, and vice versa. Has anybody encountered this before? Prop depth looks fine, but thinking may need to drop it way down so the prop wash passes below the keel? Any ideas or experience out there with bow mount trolling motors on widebody punts?
