Johnson Outboard Questions??
 

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

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.

ES= Electric Start
L = 20" Shaft

Your outboard has the "PowerShift II" lower unit - a replacement with a
similar 85-90-115-135-140 unit up to about 1977-1978 should be possible
- keep in mind that the 135/140 has a different gear ratio than the others.

On a slightly different note. What kind of expertise does take to
rebuild? I recently found a service manual and found out that my shaft
is an extra long shaft and is 26 13/32 in. Also, it has the lower unit
disassembly and assembly. I'm not sure if mine has a hydro-mechanical
or mechanical shift assembly. Is there any way to tell?

On a scale from 1-10 how difficult is doing all of this myself?

Thanks for the advise. I got the measurement from the service manual
for a 1973-77 135hp. Extra Long Shaft. I have yet to take anything
apart.
I'm low on money so I thought I could fix it up myself. How much does
it usually cost to have a lower unit gearcase rebuilt?

Your probably right that it's a 20'' shaft model, but that never
occured to me since I knew that the shaft length was greater than 20''
when I measured from the top of the shaft to where it enters the lower
unit. That's definetly one piece of information that comes from
experience (that I don't have). I think the service manual was talking
about the full shaft length, top to bottom.

I looked in the manual and it does give Extra Long Shaft measurements
for 1973-77 year models.
