Hi,
Could i draw on your experience and ask about the set up for the drive for my boat (Aeronaut Diva), please.
I decided to dispense with the supplied propshaft (not least because its so stiff it won't rotate in the tube) and am undecided as to the correct arrangement for the new setup (i'm also not sure that a 3 blade prop is the right choice so would like to keep my options open).
On both the shafts i'm considering, the propeller (when fully screwed on) leaves a portion of the shaft thread exposed when the nut is tightened against the propeller ie. the thrust washer does not sit against the tube bearing. I'm also assuming that the plain shaft should run in the bearing and not the threaded part.
So, the questions ....
1. Should I pack with washers/nut or shorten (cut) the excess thread or buy a different propeller and hope it is slightly longer (or something else).
2. Is there an optimum distance between the end of the propeller and the rudder as i can't decide whether to use the 6.5" or 6" shaft.
3. I think i may have made the prop tube hole a little too big, would you just epoxy it in or use P38? (or something else).
4. Is there any advantage to having a slimline prop tube (the 6.5" i have is slimline (but has a slight dent in it) whereas the 6" is not slimline).
5. I've noticed that many people use a U/J instead of a rigid connector - is this purely to guard against a misaligned drive?
Any suggestions/comments are more than welcome.
Many thanks,
Mark
