Thanks hiram1914 for the copy’s from the parts manual.
They look to be similar if not the same as what Buccaneer
posted. I did try pulling up on the rod Tom but no luck.
Before I took it apart I could turn the prop backwards
with out the flywheel turning but not forward so the
drive shaft must be split in there somewhere. It may just
be stuck. The recoil was stuck and wouldn’t engage and
both butterflies in the carburetor were stuck. I think
I’ll take off the drive shaft gear and try slipping everything
out hoping it all stays together I don’t understand how it
works from the diagram. Maybe it will make more sense
when I get it all out. Thanks again.A "Boat House Repair" is one that done without having tools or the skills to do it properly.
March 8, 2018 at 10:52 pm #72234I’ve had one Gale product neutral clutch spring that had the
tang broke off, therefore when the neutral lever was
activated, no neutral. With the aid of my torch I re-bent
the tang, and it worked again. Perhaps your Martin
has a similar problem.Prepare to be boarded!
March 9, 2018 at 3:54 am #72244March 9, 2018 at 12:17 pm #72248That is exactly how a TN-xx Johnson clutch operates. Not unfamiliar at all, they made umpteen thousands of them. Just a different shape. Other companies also used the basic design theory (i.e. Evinrude, Gale, Mercury, Champion to name a few).
March 9, 2018 at 1:35 pm #72249Looks pretty good inside Tubs. Must just be a matter of adjustment
to get the neutral shift working. Wonder where the your water pump
plate went?
My Martin TS 75 is a great runner, and has the "fun" little red button
in the tiller handle to play with!Prepare to be boarded!
March 9, 2018 at 7:57 pm #72264Somebody has been in this motor before me. All the
fasteners are loose. Even the spark plugs. The old
impeller was tied to the tiller. Apparently when the
motor got put back together the impeller pin and
plate were left out. Missing parts will be a big
problem because I wont know what they are. So far
the motor seems to be in good condition inside but it
needs coils, condensers, seals, impeller, that plate,
a prop shaft bearing, plugs and wires so far. Add
paint, decals, and a new grip so it looks as it did
and what ever else I may find and I’ll have more in
it than its worth. I seem to be and expert at doing
that but when you get a motor on the boat for the
first time and fire it up and it runs well none of
that stuff seem to matter. If it doesn’t run well
or won’t even start? Well I guess I just didn’t spend
enough. 😥A "Boat House Repair" is one that done without having tools or the skills to do it properly.
March 10, 2018 at 9:14 am #72296I just measured the pin that goes to the water pump impeller. It is made of brass and is 0.100" X 0.625". If you need to make that plate I could send you a template of the one I have.
March 10, 2018 at 4:39 pm #72306I feel your pain, Tubs. I’m currently fighting with a 1950 Martin 60. What’s worse is it isn’t mine and I’m not getting paid to fix it.

Thanks for the pin dimensions.
twostroke has PM’ed me that he will be seeing someone
in a couple weeks that should have the plate. If that
doesn’t work out I’ll be getting in contact with you.
Thanks for thinking of me.A "Boat House Repair" is one that done without having tools or the skills to do it properly.
