Boat Pulls Hard Left Under Acceleration
 
I am looking to buy a 94 Formula 252 SS 7.4L Bravo III 370hrs , Under straightline acceleration it pulls pretty hard to the left, Is this normal ??? I have not seen this this before with other Boats

Perhaps a worn out gimball ring pin? It usually does it when cutting off throttle slowing down but i guess it may have a similar smaller effect accelerating! Or a loose in steering system somewhere?

I didn't notice it when slowing, But I had so many things I was trying to absorb that I probably didn't pay attention to that, It steered fine until maybe 25-30 m.p.h. when I started to accelerate, Is it possible that it spun a prop hub ?? Boat has been sitting for a few years with no activity ?

Could it just be normal prop torque?

does it have both counter rotating props? matched set?

Something's not right . First off , there's no prop torque with a DP unit and there's no prop bushings on a B3 either .
If you let go of the wheel at any given speed it dramatically pulls to one side on its own ?

No issues up to 20-25 M.P.H. Then when I wanted to go up to maybe 40 or so , It was pulling hard to the left

steering actuator

power steering pump

Were both engines at the same RPM's as you were trying to accelerate? If not it will pull to the lower RPM side.
