It gives me options of three propellers, 2, 3,and 4 blade all will fit.

I wondering which you as Seal 28 owners have fitted to your boat and if you get much prop wash.

Any one know which will give the less

Would a four blade give you a quicker burst of speed from stop.

Im waiting to find out if I need to replace the engine in one. If I do will probably do the shaft and propeller at the same time
