surface drive propeller ?
 

This is a prop supposedly custom made for a 357 with Kaama drives. The only marking on it is; CT 524 0006 B. It measures 16 3/8 from tip to tip. I have a pair of them. How can I compare it to other props without knowing anything about it? How do I determine if its suitable for my application?

They look like the same one's that are on my Kaama. As I recall, they measured 16 inches too. I think they were 26 pitch, not sure. I'd run out and check for you, but it's pouring rain right now.

If they don't work out for you, I might be interested in buying them from you.

How can I figure out what the pitch is on these. If they are truely custom (they don't appear to be mass produced) I guess there would be something done to these that was not available "off the shelf". How do I tell if these are anything special?

Do they have 19 splines I think they also fit Merc small shaft speedmaster I have several sets of them all have the pitch post your gear ratio and horsepower and some one will get you in the ballpark on pitch good luck.:cool:

Fstboater, what is the diameter of the speedy props?

I have from 15 5/8 to 17.5 and have seen 18 In. I have a set of 16.5 X 26 labed choppers that worked very well before I went to bigger power.I have herd that the shaft is the same but I havent tried to swap them my self.

Need some 19 spline props.
 

If anyone has a pair L&R 16.5X26 4bbl 19 spline props I'd be willing to purchase or trade.

I have a mint pair of 16.5X31 3bbl 19 spline props.

My phone is 608-220-0983. Or you can PM me.

Thanks:)

I also have a set of 16.5X29 3bbl available too...

Thanks again.:rolleyes:

How do I figure out what the pitch is on the ones I have? The guy that I got them from said they were custom made and worth alot. How do I know if that's true?

pitch and rake indicator
 

you can send them in and we can put them on the pitch and rake indicator .we can then tell you what they are ,are far as being custom made we would know more when the props are in our hands and them we could give you our opinion.

I just checked my props, the markings on it just say 7291.

BCK there's a propeller pitch guage #950-900 available from www.land-and-sea.com for about $35.

Kaama surface drives have the same prop shaft spec's as the old Merc small shaft 6" hub speed masters, some speedy ll's, lll's and IV's. Kaama also made props with this some hub. You may have a Kaama prop, it had been a while since I had my Kaama's and I can't remember the markings on the prop.

I think CT would stand for Compu-Tech. That was the company that made the props for Kaama.
