[Rhodes22-list] Motor lift “bearings”?

Mon Jun 29 10:05:04 EDT 2020

WE have an extra long XL Honda, when up and tilted (factory electric lift) doesn't drag but dam close when healed. Goes way down deep in water on some larger roller waves it doesn't break surface. I think the long shaft would be good also,  we have tiller steer, motor has to be low enough to attach. have spare Long shaft will try it one day I think it might be better  fit    MARK

Does anyone use a 20” long shaft, considered a “Long Shaft” 
Most, including both my motors are 25” shaft. (extra long) 
If there are any Rhodes with 20” motor shafts, I would like to see the motor mount for such. 
Brt to all

In spite of that, I did most of the raising and lowering. it did take moving close to the mount and raising it hand over hand. I guess it would have been more problematic if we were not always sailing with two people but it almost always went quickly. It did sometime take a nudge on the top of the motor to get it going down.
