Sums up the entire project for me. Thanks for setting realistic expectations!

I noticed you’ve installed the impeller in the opposite direction compared to when it was removed. I do appreciate your video, as this helped me understand the sequence of the gaskets.

I use dish detergent to lube the impeller to install. Slick and dissolves in water once started. Marina told me to when I bought the impeller, worked slick.

Performing this repair in the grass is brilliant, especially by yourself. Thank you!

Well-done video. I suggest that at the very first part of the video, add a caption to tell folks to put the shifter in forward before removing the lower unit.

This is an excellent video EXCEPT you can NEVER use marine grease anywhere near the impeller itself, as it will break down the material. Inly use silicone based lube in water pump and associated areas. Mercruiser Service Bulletin.

Boy was that a wonderful video. I have a mess with my Chapparal right now. I’m hoping I can fix by watching your videos

Thanks for posting! Super helpful, saved me a boat load of $$$ having a repair shop replace the impeller!

Love the vid. Straight to the point. Fast worker, good quality video and editing. Keep it up I appreciate it

And for the rest: when he says put it "in gear", make sure it's forward gear! The little gear shifter is a PIA to align with the part on the upper drive unit. In the end I unhooked my shifter cable and just rotated it by hand from the sterndrive to make it fit..

Just some advice. Its easier if you put the impreller on the shaft first then slide the housing on and you can spin the shaft with one hand and push down on the housing with the other and it will just pop right in as long as you put grease or soap.

Thank you. Yes I see I have a problem. The weather has already changed, I will pull it apart in the spring. Please keep supplying me with the video’s. I’m not afraid to attempt it myself.

Your's is the best video I've seen on this. Great Job and thanks for Posting! I did our 1990 Baja 190 DSR Alpha 1 4.3L Mercruiser (looks just like your boat), prior to seeing your video, and watched this 2 days later to confirm. Your viewers will gain a lot from your explanation of dealing with the fasteners --how many, where they are, and in what order to remove. Great Job, great Vid!

Boy OMC for the win on changing the impeller so much easier.

[jandjmca]

It is so easy to move the little spline, and then have it not align with upper shifter channel, the only way to make sure, is to lay down under outdrive take a flashlight and see if they are lined up straight and propeller is locked in forward.(counter-clockwise)

"This is gonna suck". I loved this part.

[bwagenberg]

You didn't shift into forward before removing the lower unit.
Love how you remembered every tip at each step.
