THAT's THE solution to my problem. With a rubber band powered paddle wheel instead of the Atomic 4.
Well, not really. Like marriage, can't give up.(. this old boat and its gasoline bomb of an engine)
Here's the latest from foggy and fire ravaged Northern Calif. Humboldt Bay.
1. Boat's been tied up for over a year. Finally got a good rebuilt A4. She runs like a champ. Quiet, smooth , nice!
2. But..........new problem: Transmission/Prop shaft.
works well in reverse and neutral.....pulls hard against the mooring lines.
But in FOWARD.........there's a loud knocking noise. Its coming from the aft end of the prop shaft....at the "dripless thing" that keeps the Pacific Ocean from sinking my boat. (boat still pulls hard on lines, even in foward gear)
3. And just to deepen the mystery, if I squeeze the rubber dripless thing, THE NOISE STOPS !!!! (how about that! ain't it interesting?}
4. Me and the real mechanic installed the new engine, then re-installed it with shims. He tested the propshaft with a dial indicator...it was 40/1000ths
out of round or warped or some such thing.
He also dial gauged the two Flanges on the engine that run the shaft. The flanges were normal.
5. He's coming back to try adjusting engine mounts (shims)again, to see if that makes the loud knocking noise disappear from where it lurks inside the dripless contraption.
6. If that doesn't stop the knock, he recommends hauling the boat out (again) and having a machinest true up the shaft. (lots of work and $$$$$ and time. )
7. If anybody out there has any Ideas..about this...I'll listen to them all.
8. If not, I'm going to Staples or Office Max. They sell rubber bands in bulk.
(Toys R Us sells the boats)
Thanks for listening PS: If anybody in N. Calif needs an excellent A4 engine mechanic/rebuilder let me know. I call you with his name and # . He's in Sausalito.
see ya
