Re: Trick to putting lower unit back on?
You may find it easier to pull the spark plugs and rotate the flywheel a little at a time to line up the splines.
Put it in gear and slowly turn the prop when lifting to align the spline of the drive shaft. [links]
Tried to save some money doing it myself. It certainly wasn't complicated once I looked at the parts carefully. Probably going to have to get a pressure test done but unfortunately that will just confirm that the seal of the LU is being compromised, and probably won't show where the leak is. more
The only spot that I could suspect would be where the shift rod goes up through the LU into the main motor. There's a seal there and there was a slight play in the rod. I called my mechanic and he said a small amount of play was fine, that there's a rubber o-ring there as well that seals that rod. here
I hear you that it only takes a drop or two of water to make it look milky. I used the motor with the leak the last half of last summer and drained the LU after every other outing and replaced the fluid. Each time after letting it sit the water would work it's way to the bottom, separating from the lube, and drain out first so I got a good feel for how much water it was getting into it. I agree the oil always looks somewhat milky end of season, just from use, etc. Especially given that it's a 30 year old motor. My concern is I'm pretty sure it's getting too much water in it to run a whole season with it and then change fluid. Drain and fill ports, they are screws with plastic waashers under the screw heads, I didn't buy new ones but the old ones looked just fine and I double checked those screws before leaving the driveway. I also put caulking sealer in all the screw holes before reassembling it.
If I wreck a LU running the river, so be it, but don't want to wreck it by letting a leak go unfixed. [links]
Something to note, 9 times out of 10, the clutch dog and gear lug damage is caused by the Owner. [links]
Dogs also work on an angle to “lock” and make better the engagement. The problem described above is certainly begun by grinding the dogs and rounding the teeth, such that the angle is no good anymore. If you “snap” it into gear, they will last MUCH longer, if slowly “ground into gear” it’ll never get any better.
not owner error just poor design that the engineers blame on owner.

First step: Place tape along the edges of the area to be shot with another color. Don't worry about overlap in the area to be painted. We'll trim in a minute. However. make sure there are absolutely no gaps where the paint can get through the masking tape. more
The hood is now prepped and ready for DP epoxy primer. The it will get a coat of Sea-Mist Green with the other sub-assemblies. After the Green has dried, we will have to mask off and paint the dull aluminum trim on each half. here

Fortunately the prop shaft was not ruined by being groove from the fishing line. The seal will be replaced anyway, but it is amazing the force that has been put on the seal!
