Rotary in a boat
the boat would be a donzi classic 18
Im thinking twin turbo 20b air/water intercoolers, larger turbos I would probably go with a racing style or duoprop setup running a sustained 6k full boost cruising speed. My questio are. can a rotary handle this. Piston engines do it I cant imaging why a rotary couldnt how would I go about mounting the engine to the stearndrive. Ill probably have to have a bellhousing made. |
whew..... I dunno about full boost at cruising, but they can definatly take a beating when cooled properly. As far as mounting goes.... couldn't tell ya, I know jack shit about boats.

If you are using a stern drive make sure it can handle the HP of a 20B and the rpms you will see. A boat engine needs a lot of TQ not so much HP. Remember that.. A 6k crusin speed is prob 3.5k above what that boat stock crusises at.

My donzi right now does about 63mph at 5000 rpms.
I have seen people push as high as 6500 with built motors. Im thinking a mercruiser BRAVO2 duo prop setup.(two propellers inline, counter-rotating) |
