Re: [electricboats] Motor Mount and Thrust Plate design - hoping for feedback

Dan, that's an excellent drawing!  And I get your point strongly. I'm totally in luck that the center of the propeller shaft, at its angle hits nearly exactly at the top of the bed. Unfortunately, the beds are laid in at a 2 degree angle and the propeller shaft is at a 10 degree angle, so the thrust forces are pushing 8 degrees 'upward' on the ways. That's not too much pressure, but it makes me happy the thrust is directly balanced on the bed.

I'd love to do an additional bend (parallel) on the thrust plate. I decided against it for two reasons. First, it can only run a small distance, since I had to cut the part that goes below the ways into a half circle to fit, and second because that piece is relatively cheap so I can replace easily with a more substantial one if actual use demands it. I didn't put bends at the ends (perpendicular) because I felt the bolts would provide sufficient resistance to bending in that direction.  But I could certainly be wrong about that!  

The boat is fiberglass (balsa wood core), with a fiberglass deck and cockpit. It's stood up well these past 30 years, but it's due for another round of paint, especially some anti-fouling bottom paint... ;-)
