Built in 1981 and the cabin superstructure refurbished a couple of years ago.
The original motors are 2 decaperms that are getting very hot now.
Brushes changed in one of them which now seems to be lazy.
It is now time to change these for a more modern type of motor.
Because of the distanse from the hull to the middle of the shaft a 850 straight shaft to propeller shaft will not fit.
I've decided to fit 2 bearing blocks to the underside of the mount and fix a pulley gearbox to the prop shaft.
The decaperms where 2.75:1.
What would be the best ratio for my new setup?
