So, you have a Lark Selectric Shift? Drain the gear oil and see what comes out. Rusty water??? Get ready for some more $$$ to fall out of your pocket.
October 18, 2021 at 7:55 pm #248303LOL! Good thing it’s not the electric shift. I drained the oil and it’s not the best looking. Seems like something has seized the gears-probably rust. Will be taking a look tomorrow to see what I have!
October 18, 2021 at 8:00 pm #248308Yeah, I was just about to correct myself. The ’62 Lark was produced in both Selectric and Manual Shift.
October 18, 2021 at 9:36 pm #248312Was going to pull the lower smaller cover to take a look at the gears but don’t want to mess up the shift mechanism.
If it’s frozen, you can’t really make it “more broken” by taking it apart, right?
Support the lower in a skeg up porition, and take the screws out (including the shift pivot screw in the side of the skeg). Tap the skeg and it should pop off, exposing the gears. First time I ever did this, I was really apprehensive, but the whole “what’s what” revealed itself pretty quickly. It’s an elegantly-simple, simply-elegant design that you’ll come to understand and appreciate very quickly!
Good luck!

October 18, 2021 at 11:06 pm #248326If you can turn the prop shaft, that indicates both the forward and reverse gears are free and turning on the shaft so the problem is probably the large roller bearing which the pinion gear fits in.
What you want to see when you open up the gearcase are clean and oily gears, not gooped up rusty ones.

October 19, 2021 at 6:42 am #248337Thanks! I appreciate the confidence boost! Looking forward to getting this motor operational again.
October 19, 2021 at 6:43 am #248338Thanks everyone for the pictures! Those are a great reference! I will post what I find…
October 19, 2021 at 3:26 pm #248348Well the pinion bearing is frozen but the prop gears are not too bad-I cleaned them up and it was old grease and a bit of lake gunk. Definitely all the bearings need replaced. Also, it was missing the cradle holder piece so somebody was playing around in here in the past.
What is the best way to get the driveshaft bearings out of the lower unit? Does it require a special tool? I have a slide hammer bearing removal tool but don’t want to damage anything if a low cost alternative is available. Thanks again everyone for your input!!!

October 20, 2021 at 11:23 am #248384I had one where a vane was broken off the water pump impeller that resulted in the water pump being jammed up so the driveshaft would not turn.
Looking at your last photo, I think you found your problem. If it were mine, I’d look for a used lower unit assembly, preferable with driveshaft, or look for a parts motor with a good lower.
