I have search all over the forums and can't get a clear answer.
1988 Evinrude
15HP
Longshaft w/extension plate
I had to pull my lower unit and powerhead to fix a water flow issue - it was the classic "detonated" grommet blockage up at the powerhead. The motor was overheating and there was no tell-tale.
Anyway, I'm having an awful time getting the lower unit on correctly so that it will shift FNR correctly. No matter what I do it seems to only give me a F and N or N and R but I can't get all three!
I will rotate the flywheel just a bit and the LU will snug right up. I've tried every combo of shift lever/gear position there is before attaching the coupler and will only get 2 of 3 when LU bolted tight.
When the mid-section is gapped 1/2" to tighten the coupler it will shift easily into all 3 gears with a nice clear, crisp click. Once pulled in tight, nope! It's like shift link rod is suddenly too long. There is only a tiny gap at the butt joint inside the coupler and it holds tight.
When I first got it home I fired the motor up a few times on the back of my boat just to see how it acted and shifting was no sweat at that point - fully functional.
The water pump and impeller were just replaced by P/O who sold this motor to me cheap because of the water flow issue and he had other projects so I didn't replace them at this point.
In order to get moving on forward on this I started it in a barrel today and got a solid tell tale so at least that is working now.
