When I started searching to replace my two vacuum wiper motors on my Grumman several years ago with two electric motors, I ended up getting WEXCO motors from Grainger. As I recall, there were several models to select from based on size and shaft length, etc.

The ones I got work just great, but the motors are too big to go in your 37. I have a 41, so I know about the limited space up there. But, you may find a model that will work for you. If you do, let me know. I have two electric motors for my 41, but don't know if they work yet and I will be getting to that point in my build this season.....I hope.

Good luck!

Correction: Looks like I got the switch from Grainger, but I got the wiper motors, arms, and blades from Zoro Tools.
