Mercury Blackmax power trim pump

[cam1399]

I have a blackmax 150. This trim pump is real weak when cold. Clicks a few times until it starts picking up but then it’s fine. I think it’s about burnt up. Fluid is full. What is the part number to replace? I’m having trouble finding one. Thanks

Ebay.. justa 'bout any mercuriser pump with tank will work if ya have room... doesn't hafta be same as what ya got.. ya might need ta get a hose shop ta match tha fittings but tha pumps are for tha most part all tha same....... below is just an example.. some will have solenoids and all.

if ya have a serial number can get ya a part number but if ya go that route its gonna be expensive.........

Okay thanks. I was kinda thinking I could go that route. Does that one have a built in solenoid? The 3 wires hook straight to the switch?

that one doesn't have 'em.. some will and some won't be included.. depends on tha seller.. they all will need to go thru solenoids..

Gotcha. No big deal. Thanks I appreciate it.

When mine is cold and been sitting awhile. It will click a few times at the solenoids then it takes off. It’s slow at first but does great after that. Does that sound like the pump is going bad? It was a tad low and I cleaned up a bunch of the wires just now where someone does a bad job wiring it in

hard ta say from a "keyboard"???.. usually they work or they don't!.. ya might clean it up (wiring and connections, 'specially grounds) and see what it does???................
