Hi Gang,
We have a 24ft. aluminum Jet boat that was powered by a 8.1L gas engine and would like to use a Diesel instead of the gas.
The RPM of the diesel is a lot lower than the gas engine and the Hamilton Jet likes higher RPM. I think we could trade the diesel's torque for more RPM. The boat might not be as fast as a high RPM gas powered but might be a cheaper to run and less likely to catch on fire.

So we were thinking about using a 4X4 transfer case and sending the power from the engine into the "output" shaft and getting a 2 to 1 increase in "input" shaft speed when in the old low range.
Hooking the transfer case's old input shaft which would now be the new output to the Jet's input.

Anybody know how the transfer case is lubed? Is the chain drive to the front axle needed?
any thoughts
thanks
Hank
