The new prop hasn't been fabricated yet but we'd just gotten the bids on it so that's something to figure out now rather than later!
There is one thing certain and that is if the transmission has stood for a long time , say > 3years

then the seals on input and output shafts would have hardened up - and when eventually running again would probably leak! Therefore, absolutely nothing lost in your present replacement exercise.

If the transmission is not yet coupled to the engine - then by turning the input shaft 360 and measuring degrees turned on the output - the ratios can be confirmed as matching what is stamped on the S/N plate.

good plan but I still will check the gears just to see if they're as per the drawings and parts lists for this transmission.

You 2 are probably the one of the most capable couples I know of. I have faith you will sort it out................
Thanks for the kind words . We're just a couple of control freaks in our own very special way...

Dear all:

I thought I'd follow up with "what happened" on this topic. Turns out MER couldn't actually get the part either. They tried and tried but kept getting something that was not right. I ended up returning two different ($35 each) seals to them that were not right.

I tried the NAPA folks and other places that cater to trucking--but no go.

After a couple months and needing to get this transmission back onto the engine and in the boat--I went to a local industrial place (called Motion Control Inc) and looked through their SKF seal catalog to order a replacement seal. I ended up making the "minimum" order of 3 seals at $2.98/seal--including shipping/tax the total was around $18--so $6.00/seal

When I made the order at Motion Control, I also checked with the folks at Hurth yet again. They had something they "thought" would work--at about $55 plus shipping for 1 seal. I figured that was my back up if the Motion Control procured SKF seals didn't work. But all is well that ends well-- the seal was perfect and I have not one but TWO spares! at a very good cost savings.
