High Thrust Prop for '73 6 HP Fisherman

[triton318]

Yesterday I purchased a 1973 Evinrude 6 HP Fisherman outboard, model 6502/6503. It's in great condition and I'm looking forward to using it as an auxiliary on my 28' sailboat.

Does anyone know if someone makes a high thrust prop that would work on this motor? I know that some outboards people buy for use on sailboats have high thrust props because the boat is heavier and non-planing.

Thanks in advance for help/advice on this.

Evinrude doean't offer one, not sure about other prop companys.
