Re: Replacing Lower Unit Johnson 10hp
Yeah I have pretty long arms, but don't think I could turn the flywheel while lining up the water tube and sliding the gearcase up!
Put the shifter into forward on the motor, to get the upper shift rod up and out of the way for now. Grease the water line and grommet on the impeller housing to aid in sliding together. Push the lower shift rod down, to put it into reverse. Grease the splines, but NOT the top of the driveshaft or it will not go up. Now, slide the gearcase up slow, ensuring the water line slides into the impeller housing grommet. Once you are sure that it is in, push up until it stops. While keeping pressure up, turn the prop CCW slow and it should pop up the final inch or so as the splines align. Easy Peasy.
Install a bolt to hold it, then connect the shift rod. Test all the gears, and when you are happy that all is well, install the remaining bolts.
