Thanks jatr24 and racerone. After watching a couple vids, it seems like I might want to punt on this until the season's over. It doesn't look that difficult to rebuild, and except for occasionally having to manually release, the trim and tilt work well enough to finish the season. I'd rather not...
Actually - I just watched a YT video posted by Dangar Marine, and the procedure to replace the PTT unit on this outboard does not look difficult...even for a mechanically-challenged guy like me.
Thanks for the post raceone - I'm looking at new and used right now.
One other thing that seems odd about the PTT. I had an Evinrude 70 on my previous boat, and when I dropped the motor onto the trailering bracket, I would typically continue to press down until the two trim rods were fully covered. On the Johnson 175, those trim rods do not lower at all. I've...
I corrected the dreaded "down hop" by draining, filling, and bleeding the tilt/trim system and now it works smoothly in both directions. However, I've had a problem with the outboard getting stuck in the tilt up position for a few years now, and the refill/bleed did not fix this. I can hear the...
OK - final update for this thread. The '98 Johnson Fastrike 175 has a new lower unit (SEI #SE306), a new upper driveshaft, a new starter because the wrong replacement was installed some years ago (bottom mounting hole did not line up, a new starter solenoid, and a new VRO pump. I spent a few...
Tonight I'll be digging up the torque settings for the lower unit bolts and snugging them up. That should be it for the lower unit replacement. Then I'll redo the compression measurements.
I replaced the lower unit on Saturday (along with the water pump) and also replaced the starter and solenoid because they looked thermally stressed from my adventure up north. The motor starts and runs, sounds great, and the water pump is doing its thing. I have not remeasured the compression on...
Yes - and thanks flyingscott. We're dropping the lower unit this weekend, and I definitely will retake the compression measurements. Part of me wants to take the old LU apart at some point and view the destruction. First priority is to get back on the water though.
I was talking about removal and reuse of the shift rod. Isn't it as simple as unscrewing from the old LU and screwing into the new one to the proper length?
Thanks for the tips kevinj. I won't throw anything out until I'm back on the water. I think I remember that the shift rod just comes right out after enough turns. I will retake the compression measurements. Even though I'm 68, I'm a rookie when it comes to motors.
Thanks racerone. Do you have any comments on the compression numbers I posted in post #6? They seem a little low to me, but no obvious busted rings/pistons. Are these typical numbers for a 25-year-old outboard that needs a rebuild?
