Propulsion System
Mo’Chuisle is powered by a six cylinder Isuzu 6BG1 diesel engine. This is a 114 continuous hp engine @ 2500 rpm. The
normal cruising rpm is around 1650 rpm which utilizes 80 continuous hp for 7.3 knts.
The main engine is coupled with a Borg Warner Velvet Drive Transmission, Model 10-18 with a 2.1 to 1 ratio .
Mo’Chuisle has a 1 3/4” SS shaft approximately 10ft long, with a 24 x 17 left hand bronze propeller.
A PYI drip-less shaft seal is coupled to the Fiberglass shaft tube, which has two sleeve style water cooled cutless bearings
inside. There is a shaft brush connected to a zinc on the hull exterior to aid in reducing electrical interference and provide
added electrolysis protection to the shaft and propeller.
There is a hydraulic disc-brake mounted between the couplings, that is released when the engine starts, and engages
when the engine is stopped.
