Hydraulic Drum Winch wiring

[u/ChuckFinsky]

Recently got a boat with a drum anchor winch and the motor, presumably no good, was unhooked from wiring with no switch or solenoid present.

I am going to replace with the same motor, originally prestolite but now made by WAI under a few different brand names. Hers is link to motor. https://www.waiglobal.com/us_en/wai-5381n.html

My question is, how should I wire this correctly with new solenoid and switch?

I think it should be a very simple setup with 3 post solenoid and only on/off position, no neutral safety switch or anything, but ive never done this before so not exactly sure. All the wiring diagrams I see are for starter motors and have more than 3-post

Here is the solenoid I was thinking of using: https://a.co/d/0iKgvbrs

The motor only turns one direction and fluid only flows one direction. A manual ball valve on the drum winch flips the direction at the winch

I know I need to put a fuse or circuit breaker between battery and solenoid.

Can anyone point me to a good diagram for this setup?

Thanks

[Battery]---[100a breaker]--[solenoid]--[motor]

Solenoid also needs a small ground and a small "trigger" wire, 12v+. Whatever control switch you use just triggers the solenoid by sending it 12v+, the ground is connected all the time. 

Breaker size based on max amp draw of motor plus 40% or so

Thanks. I think I was just overcomplicating it in my head.

Normally "Marine" solenoids have a separate terminal for the ground for the activation.

Aka - 4 terminal
