Default More electric power for the Johnson Sea Horse 85....

I'm doing some thinking. I'm not a slave to fashion, but I am to
function. There's enough shaft space on the top of my v4's flywheel to
mount another pulley, and I'm considering mounting about a 50-75 amp
12volt alternator on an external bracket and running a belt though the
cowling. The reason why is because the meager 10 amp stator on the
engine itself jsut isn't going to cut it. I can modify the brackets so
the external alternator is independant of being under the hood with
the gas fumes. I know the 85 will suck gas anyhow, so what's a bit
extra drag?

And I know the contraption will look like a tumr hanging off the side
or rear of the engine, but I can do some specific cowling work to
modify it so it isnt' so 'tacky' . Even Rube Goldberg had good
ideas... sometimes.


But also like what Gfretwell pointed out, once can make a charging
system off a small gasoline lawnmower engine contraption. I've done
this too. But there are some really neat, small and highly efficient
alternators ont he market noow that have less drag of horspower to
produce the same amount of wattage as apposed to even the automotive
units made 20 years ago.

In other words, I can make a simple 30 amp, self regulated unit run
off a 40cc chain-saw engine.and the exhaust can be quieted down so you
don't hear all the buzzing racket, and this can be an advantage
because both engines would share the same fuel mixture.

OR, I might ust go by an 1800w gasoline inverter power pack.


Even though they may not go very far, the wheels are turning
