Thanks for the video! Im going to try that on my black max tomorrow 😂

[@thehandyhomeowner9781]

2 things. Make sure you wipe the grease from the top of the shaft before putting it back in place and make sure you get the shifter piece in the hole when getting the lower unit raised up that last inch and into place. It can be tricky.

[@user-bl2is9ic5w]

Thanks for the video . I drained the oil and it came out milky . What do you recommend I should do next?

[@ProWrenching]

Sounds like you have a leak. You should have the lower unit pressure tested for leaks.

How's your black max running? I have a 1986 and replaced the water pump and thermostats and now it pisses well but gets hot when WOT. At idle it's dead center on the temp gauge but quickly climbs at full speed. Do I need to replace the poppet valve?

[@ProWrenching]

My black max is running great. Yes- It sounds like your next step would be to replace the poppet valve, if you’re overheating at WOT.

Is any gasket sealer used where you drop the lower unit or in-between any of it?

[@ProWrenching]

No, I didn’t use any gasket sealer.

@@ProWrenching do you know if mariner and mercury parts are interchangeable. I have a 1995 150hp mariner and seems like only thing I can find is for mercury. I know mariner is made by mercury

[@ProWrenching]

@@AlexLopez-tk1ft yes- As far as I know they are the same.

Watched other videos and it said to put the boat in gear when removing and reattaching and now the motor is stuck in gear and won’t go back to neutral. Did you do that on your install?

[@ProWrenching]

That’s the way to do it. Make sure your lower unit is still shifted into forward gear when you reinstall so it’s aligned with the shifter.

[@VernonCrumpSr]

Thx pro wrench. Sounds like a key step 🤦‍♂️

[@charlietucker9403]

What’s the lil black tube for

[@BadarseBreakout]

What torque for pump housing bolts

[@ProWrenching]

35 inch lb torque screw, 50 in lb torque nut on the water pump body

[@patrickseibert7735]

Do you have to drain the oil? And if so what’s the reasoning?

[@ProWrenching]

Yes- The water pump gaskets also seal the lower unit where the oil is, so it’s good to change it when you’re installing new seals.

You don’t have to drain the lower unit to do a water pump.

[@ProWrenching]

Yes- With the price of the lower unit oil, if you have already done your yearly maintenance, & the water pump seal hasnt gone bad and leaked water into the lower unit, you don’t have to drain it. Good point.
