Consider J-prop and max-prop. I have a 3 blade max-prop and it works as good in forward as it does in reverse. No complaints. The only real disadvantage is that it is a feathering prop... So underwater obstructions may not slide off like they can on a folder like a gori. Initial cost seems high and refurbish costs seem about the same as the cost for new j-prop. IIRC, Ken Heaton has a j-prop and as I recall I found myself envious of his setup.
The max-prop does have the ability to adjust the pitch which means fine tuning and matching to many different boats and engines is possible. The setup on the max prop is a bit more time consuming, messy, and (on the old versions) impossible to do by a diver underwater. I think one of the other manufacturers has a more automatic and less involved setup. I would suggest that you ensure any folding prop options be geared.

GORI, on the other hand, have recommended: " 15" x 12 x 2-blade RH – or 15" x 12 x 3-blade RH (at twice the cost) the cost of the FlexoFold and Gori 2 blade folding props are approximately the same after shipping etc (about $1200 USD) I don't know if I need a 3 blade prop and the cost is substantially higher. I would appreciate any opinions Wade Oh Boy 33 MK II _______________________________________________ Thanks everyone for supporting this list with your contributions.
