    Replacing water pump impeller for first time

    It started easily after sitting all winter and pees like a race horse! It's ready for the lake!☺️

    Replacing water pump impeller for first time

    Yes, the plastic guide tube that came with the new pump kit is installed into the pump outlet and I put a little grease on the rubber seal that's inserted inside the pump outlet. The metal water tube slid into the guide tube at the pump outlet easily. The plastic guide for the shift shaft I was...

    Replacing water pump impeller for first time

    There was no plastic shift shaft guide in this motor when I pulled the lower unit off, that's something I looked for and was surprised I didn't see it. I was hoping it was just a guide and didn't do anything else, but I had very little trouble sliding the shift shaft together once I found the...

    Replacing water pump impeller for first time

    I'm putting the lower unit back on and for some reason it doesn't want to go on the final 1/4". The shift shaft slid in place nicely and I double checked shifting gears with the shifter with the appropriate prop action. I'm assuming I have the drive shaft splines lined up or I don't think I...

    Replacing water pump impeller for first time

    My prop is aluminum, it probably wouldn't make that much of a difference in weight. I don't have a stand, but I do have a couple of 6" thick blocks of wood and was just going to sandwich the skeg in between and clamp it with a bar clamp. They're wide enough to keep the whole thing from falling...

    Replacing water pump impeller for first time

    After I investigated a little further, I see a label on the power trim pump that says to enable reverse lock to turn it one way, and to disable turn it the other way. So, aha, that is how it works! I would assume there's some built-in safety mechanism to allow the motor to swing up if you hit an...

    Replacing water pump impeller for first time

    Do trim models have a mechanical reverse lock mechanism, or is it handled with the power trim? I looked and I just don't see anything that would engage the tilt angle pin. I can raise or lower the motor in neutral or forward (I didn't try in reverse). The service manual describes how to check...

    Replacing water pump impeller for first time

    That's the way that the Mercury service manual says to do it, but what I didn't understand was why they tell you to start off in forward gear before you tilt the motor all the way up and then shift to neutral after the latch is locked.

    Replacing water pump impeller for first time

    From what I've read, it seems pulling the LU off and replacing the impeller and all the gaskets is fairly easy, however sliding the lower unit back on can be a bit of a nightmare! I have the Mercury service manual for my motor (1978 1150 ELPT), and it states to First shift into forward gear...
