With adequate air circulation can anyone see any potential issues here? I would build the boat with this purpose in mind so adapting something to fit would not be a problem. Robin Two strokes want to run at one speed... It would be very inefficient in that situation. Not to mention, unless it was a race boat, the sound would probably draw gunfire on the local lakes  Err - like the Yamaha 250? The one that used to trounce 500 cc 4-strokes in the old days? Even with its tuned pipes it has usable over several thousand RPM. Actually it is the tuned exhaust that wants to run at one speed. The old 2-stroke motorcycles - Famous James, et al, were happy to run over a fairly broad range. (So is my 2-stroke outboard :-) Cheers, Bruce (bruceinbangkokatgmaildotcom) |
