I know nothing about your particular motor but when I needed a new lower
unit last year, everyone was talking about a shot shaft/long shaft, 15 or
20" and I found there's no such measurement on the motor. Measure your
transom height which should be close to one ot those numbers.

I'm very new to boat motors. I've got a 1973 Johnson 135 Outboard on a
old Caravelle. I recently rebuilt the transom and floor, but when I put
the motor back on and ran the boat the lower unit leaked and stripped
the lower unit gears.

I'm looking to buy a used one. Does an ESL model have a longer shaft
than normal?

Any help would be appreciated.
Thanks, Jason
