I tooB always look for savings when it comes to boat gear, and although this
solenoid is about half the price ofB aB watertight, continuous dutyB marine
unit, I could not justify it for the following reasons:
The solenoid is installed belowdecks in a completely dry location.
ItB is an automotive solenoid - it is not watertight andB is only
ratedB 100A for 6 minutes with a 20% duty cycle -B windlass duty is always
100%.
True. However, my windlass is 24 volts and draws about 50 amps. Lifting my
entire 400 feet of chain only takes about 4 minutes. It's very unlikely this
will cause a problem.
Also, theB 6mmB terminal studs are too small for anything larger than 1/0
wire terminals.B
The specs state that it is forB permanent magnet motors, but many windlass
motors are shunt-wound with brushes, and need larger contacts due to inrush
current when starting.B
Also correct. The Ideal uses a reversing-field motor. Inrush current is
always a problem. It's possible this contactor might have problems, I'll see.
However, for me the big advantage is that this is a single unit, as opposed
to 4 individual solenoids, each with multiple exposed contacts.

Correct. I run #2.
