design of transmissions
Thanks, Denr, and tsenator, for responding. I didn''t ask any specifics because I wanted to glean the answers for myself, but just couldn''t seem to find any worthwhile info after looking at over 50 web sites.
The question was prompted because none of the group I mentioned above (including myself) had ever seen the insides of a marine tranny. One of the guys was claiming that putting your tranny in gear while sailing with the engine off would NOT lock the shaft because the coupling between the engine and prop shaft was all hydraulic.
I started thinking about all the possible methods for getting power to the prop (hydraulics, planetary gears/bands, multi-disc wet cluthes, spur gears, cone clutches, etc.) and realized that I had no idea what design(s) is/are actually used.
As to buying a book, I have been so happy with the info from Calder''s Cruising Handbook, that I will just go buy the mechanical repair book, too.
