Default Amps draw per horsepower

Hi,
All this talk about circuit breakers has reminded me of something I
have been meaning to do.

I have a 1.5 horsepower 12 volt electric motor that powers my anchor
winch by a worm wheel.

Can anyone advise what the current draw is likely to be under load or
is this not enough information?


1 HP = 746 Watts,
1.5 HP = 1119 Watts,
1119 Watts / 12 V = 93.25 Amps

If it has a fuse on it, I wouldn't be surprised if it were quite a bit
more (150A?) to allow for the starting load.

This is all theoretical, of course. Is there a fuse on it?
