RE: M_Boats: Short shaft vs. Long shaft for M15?
long-vs-short shaft outboard motor for the M15
No experience in long vs standard, but a datapoint: I've used three ss motors on my M-15 (old Johnson 4HP, Honda 5HP and Honda 2HP). They all pop the exhaust out of the water when I go forward, but otherwise work just fine. The Honda 2HP has an air-cooled engine -- only the exhaust is water cooled, so this lifting from the water isn't a problem. A standard shaft is better if you plan on ever using it as a dinghy motor (the other use for my Honda 2HP). Giles Morris Arlington VA Vancouver 25 "Dolphin" Montgomery 15 "Umiaq" Sundry small craft
Stan, Free opinion - worth every cent. I prefer the long shank for the additional prop depth when there are waves or I am crossing wakes and for keeping the exhaust underwater a bit more often when I go forward with the motor idling. The keel is still deeper so there isn't a greater risk for striking something with the prop. Stan Winarski M-15, #177 Carol II
