Default Trim Pump

2006 1800MX 3.0

the other day my trim wouldn't go down.
Up worked no problem.
after trying it about 20 times it finally started working.

I thought I might just replace the pump and solenoids but
im having trouble identifying the pump so I can get parts.

it has SAE J1171 Marine on it

I looked at the mercury parts catalog but there are a lot of them

any ideas on how to know which one I have?

I attached pics

SAE J1171 is a specification for marine parts that meet that ignition protection standard. Not a Part number.

If the pump itself works fine, just replace the solenoid.
The most common solenoid is a 89-96158T.
Use a site with specific parts lookups based upon your drive type and serial to verify.

It's a reversible pump. If one direction is working, then the pump should be fine. This is most commonly a bad solenoid. If one is bad, then replace them both, because the other isn't far behind.

A temporary method to hopefully get you out of a jam is to hit the button in the direction that isn't working as many times as fast as you possibly can. The switch collapses a gate in the solenoid that closes the circuit. You should hear it 'click'. slam it closed in succession and you can usually knock enough corrosion off to get it to work (enough to get home).

Another work-around and test is to take a screwdriver (I prefer an insulated handle) and bridge the gap across the posts on the solenoid. This effectively 'jumps' the solenoid by bypassing the internal gate and closing the circuit externally. This will both get you out of a jam and verify it is actually the solenoid that is bad.

Remove one from the pump bracket and buy two. Then replace them both.

Yes. Same part is used as the slave solenoid in most applications.
