Re: Help! My transmission won't go into gear

Rumlater;
I have no idea what caused the seal to start leaking, but it is clearly shot. Oil just runs right out after filling. Sounds like too big a job for me (at 74 years) to remove the tranny with the very tight quarters on my boat.

Lesterbutch;
Still don't quite understand the "slide the shaft back in" concept? That would be an easy fix it that's the problem.

Thanks for the tip on the yanmar dealer in Ft Lauderdale.

Re: Help! My transmission won't go into gear

Coming into Lahaina harbor with following waves I went full reverse to keep behind the swell. The shaft parted from the coupler and the 3 blade prop pulled it aft pinning the rudder to port. As the boat broached the 8' wave in the channel entrance she drove hard to starboard and into the harbor by the grace of God.
Regular maintenance for the last 30 years dictates checking the tightness of the coupler screws every time I change oil...

Re: Help! My transmission won't go into gear

Lester, does your shaft coupler not have 2 squared headed boats that have a round nose on them to sit in a couple of holes in the shaft? And for added protection these are usually have a stainless wire through the head so they can not vibrate out

Re: Help! My transmission won't go into gear

BobL, talking to a guy at the SYC he said it could be possible to change a seal on the outboard end by pulling the coupler off and using packing puller hooks to pull the seal out then press a new one in, still would want it on the bench instead of the boat

Talked to the mechanic at Complete Yacht Service in Ft Lauderdale. He said the best (and probably only) way to pull the seal and replace it properly is to pull the transmission. YUK!
Looks like "outboard city" for me. Anybody wanna buy a sweet little 1gm10? You'll have to pull it out yourself

Really? Lahaina without steerage with that tight dog leg to starboard. You are one lucky dude! Well done!

I had the same thing happen backing out of a slip in Kaneohe at the Yacht Club. Luckily I was still in the harbor, could tie off to a mooring post and could borrow some tools and dive down to see what was happening. It was a friends boat that I was taking to Pearl Harbor for him (a Celestial 46). I made it by slipping the shaft back in place and tightening the keeper bolts but was very skeptical about it the whole way.

PROBLEM SOLVED:My transmission won't go into gear

Lesterbutch and others
Found the problem!!! Loosened the flanges at the transmission and found a big (1") nut had worked itself loose and thus allowing the trans/spline flange to slip back about an inch. This let all the fluid out of the trans and disengage the shaft.
Put the nut back on tight and whadda ya know...it works. Whew!!!

Thanks to all.

Glad you got it straightened out. That certainly wasn't too costly.
