90 hp shift issue?

RidgeRunner · #1 07-28-2012, 06:51 PM

What am I looking at on a 90 Johnson that won't shift?
Cable is working and smooth, moves the linkage and the shift rod.
I can't remember how it attaches in the lower. Starts in gear irregardless of position of the shift rod (thankfully). I'll drop the lower after I finish the lobster dinner and post back. Thanks in advance.

before you drop the foot, i'd disconnect the cable at the engine and see if you can shift it by hand

enjoy the dinner

Do this first, and if it still won't shift then there is a chance you have broken the pin that holds the shift fork in place.

Disconnected the shift cable to try moving the lever by hand, no good. Lever moves the shift rod just as it should and same as it does with the controls hooked up. I could get a dirty neutral by moving the lever forward all the way. Dropped the lower, looking for my manual.

Found the book. Done for the day.. The entire lower has to come apart. The screw up is in the nosecone forwardmost. Now we get to see what all the bearings and gears look like.

AGAIN!

I've got one apart out in the garage. There not to bad to tear down except for getting the driveshaft nut off the pinion gear.

10-4 Ferm, as I recall it takes a 12 pt thin wall socket and a pipe wrench on the shaft. I had it apart to change the dog gear a while back. Discovered some large pieces of the pinion gear missing so I changed the gears too. I am hoping it looks better this go-round. Just recooperating from vacation so it ain't gonna happen today. Funny thing, it acted up a day or two before it quit. Wouldn't go in reverse for a second, like it was in a bind. Went to forward OK, then went right into reverse so I didn't think anything about it until it went south. Whatever it is was hurt and finally gave up. Manuvering in for the kill while chasing lobster requires a lot of gear changing on the skiff. I worked it to death.
BTW- Your economy tune allowed me 17.5 MPG down and back with the skiff in tow. The wife's 5.3 Tahoe got about the same just hauling itself down and back and she was drafting. Thank you..

Good to hear about the milage, I just put that same basic tune in an 07 LMM with DPF delete and he is getting a shade over 21 mixed driving. There is a roll pin I belive in the shifter portion that can shear off, sounds like that may be your issue.
