And now for a confession...
While installing the prop shaft;
The prop shaft needed to be slid in from the rear, because space was too tight between the engine and the shaft log. I therefore needed to install the bellows and graphite seal before installing the prop shaft. No problem there.
Then I needed to install the stainless seal over the shaft. No problem with this either - I sanded the edges of the shaft and keyway with 600 grit paper, coated the shaft with Dawn, slipped the seal and rubber rings over the end and up against the bellows. (I still haven't used any of the set screws yet).
Then I needed to install the coupling. I coated the inside of the coupling and the keyway with Tef-gel, and slid the end over the shaft. Here things go awry.. While I could get the coupling on the shaft, I could not fully seat it. I can't fit a hammer between the coupling and the shaft to tap it. So, I put a block of wood (1½"pine) between the coupling and the transmission, to act as a shock absorber. Then, I tapped on a block of wood on the aft end of the propeller shaft to push the shaft into the coupling. I was basically hammering the shaft forward into the coupling, and against the block of wood, which was held in place by the transmission flange.
Well, lightly tapping didn't get the shaft into the coupling, so I tapped harder with a bigger hammer - for about 15 minutes
. The coupling is still
about 1/8 inch from where it needs to be, and I am frustrated.
My plan, when I get back to the boat, is to use a series of wooden blocks to brace the coupling against the transmission, and NOT the flange. Then to heat the coupling with a propane torch, for about 10 min to heat, and hopefully expand the coupling. Finally, what any red-blooded-american-boy would do, I plan to use a bigger hammer!
