i think we have narrowed it down to the oil pump where the pump housing is attached to the block. Bearly visible when started and run in driveway but way worse when the boat (13 whaler) is in water and put under a load.
O rings in oil pump maybe? Anyway to change them without removing powerhead?
any suggestions would be appreciated, thanks
