I got a 2001 150 suzuki 2 stroke on my 1987 200 osprey. Problem is this engine is the 2.7 liter block(same as the 225hp), so the scuppers sit below the waterline. Does anyone have any experience with the ball scuppers? How well do the work? It may be worth my effort to fill in the drain well so the deck drains straight out and raise the scuppers an inch or two.
