hello there, i need to know what size propeller i need for my boat. Engine is a lister sr3 air cooled deisel marine 20hp , lister gearbox, boat is 21 ft clinker fishing boat, any ideas please ?
BTmarine props(Andy Tudge) and Lancing marine are pretty good. You will also need to give them the engine revs and reduction ratio (if any),also shaft size and taper and key size.
