Jubilee has a 18hp Volvo
. The original owner ran Engine
off of the diesel
. This involved a twin-belt PTO pulley up front, belts going up to the top of the engine where they ran to two pulleys on a drive shaft that went to the rear of the engine. There one belt went to the watermaker
and one to the refrigeration
. Both systems are no longer installed.
We removed the shaft, but the PTO pulley, and the mount for the shaft above it, are still in place. The shaft contraption must have weighed 40 lbs!
I am wondering out loud about mounting a large alternator
onto the pad where the shaft was attached to the front of the engine. It seems it would be easy to line it up with the PTO pulley. There is a used 165a unit for sale
on our marina BB. I was thinking I could design the installation
with a rheostat to adjust the output. This way, if we needed the 18hp for propulsion
, we would have it, and could nicely load the engine for charging
when required, for little $$$.
So a few questions.
1. How much load would a 165A alternator
put on a 18hp engine. The stock alternator is a 50a unit, which I would leave on dedicated to the starter battery
2. I have a 12v book with the scematics for a dial down system. Will this allow me to dial things down to 0 output?
3. How much drag do you think the freewheeling double belt alternator will put on the engine, when not calling for amps?
Anything else you care to comment on, please do.
Thanks in advance,
