When working with us you don't have to worry about getting stuck with a propeller that's the wrong size. We wil manufature propellers we feel is right for your application. If it's not right we then manufacture a new set with the proper adjustments made to them. We won't grind and bang on a new set of props to try to make them work.

The cast Mercury SSM props are about 2" taller in pitch than marked. Thats why the Hering 37's and Mercury 35's run the same rpm.

Give us a call and we can go over all your numbers and go from there. Our goal is not to just sell you another set of props but to make sure we get your boat running where it runs it's best.

Thanks for the quick response, sure makes the mercury props seem to have a better slip %. I will call next week.
Thanks Keith

HP, Just a FYI

There are other reasons besides initial pitch numbers as to why the Merc props record lower rpm's than the Herings (K series propellers). Only consider down sizing by "1" inch when going from Mercs to the Herings. Vintage, vintage, curves and progression, trailing edges. Are the props new? These things affect your readings and require a initial change of only 1 inch of pitch.

Diameter increase? this isn't my thresd but...............

NO

Thanks for calling today HotPursuit. I am really looking forward to working with you. Let me know what you come up with and then you can make some informed decisions.

:d

TU what does a blank one look like,sq block?

It is standard a propeller casting. However the blades are a bit thicker for machining purposes though. After machining they look like this.....

Nice looking,I am assuming it starts out as a cast product,not a block of stainless ? Do you have a pick of the casting before machining.Curious:drink:

The block of stainless would be billet and that would be very expensive. I cannot post a pic of the castings, but envision a propeller with thick blades and the color is a greyish color.

Ever wonder why forged props cost so much more than cast? :eek:
