Re: [Electric Boats] Prop issue?

 

Mike, Increasing pitch will increase the amp draw and speed at full throttle.

Subject: [Electric Boats] Prop issue?

 

I originally spec'd out my 30 foot 8 ton sailboat with it's current 3 bladed prop. Which I thought from the documentation was a 16 inch diameter, right handed prop with a 14" pitch. When I was polishing the prop last spring I came across some of the stampings on the prop which lead me to believe I have something different than I thought. You can see the markings I uncovered in the second photo located here:
It appears to me that the original 14" pitch was stamped over and 13 is stamped in it's place. I've been happy with the performance of the prop (except no regen) with my electric system but, I am wondering if I would get better performance with a 14" pitch as I thought I had. Can anyone shed some light on this issue and what I things I might want to change. As I said I have been happy with the performance as is but, I am wondering if I can make it better.
 
Capt. Mike
