Alex,

You still running the old reliables?

I can get you plenty of them if still needed.

Let me explain while I'm searching for the "old" reliables.

I tried the 1717-19-38 / 1719-19-38/1817-19-38 and the 1819-19-38 on my 21.JAE rigger.

All props didn't worked! I also talked to Niklas Edlund and he had the same results with his 21 KEPS rigger ( he is using the old reliable 50x69)

My "mentor" Don Maher told me last year .......... " if you want to understand props ..... by them raw and cheap and bend the **** out of them to understand what a prop is doing ........ !!!!!! So I'm in the learning progress to understand props.I even did some Lynx cuts on a CNC milling machine ( I know its a little overkill).

By the way ...... I'm open for ideas , suggestions and advises !

Alex,

I understand your problem, did you sharpen and balance them only?

I think you picked the ones with too much pitch ratio and too much

cup in the trailing edge for your set ups. I like the 1715, 1815 on my

21-Hydros personally. I like to run the 17 degree rake ones in the Spring

and Fall and the 19 degree rake ones in the mid summer season. The

17/45% have 7% more blade area and throw more water and load the

engine more. They are also the ones that were designed for electric boats.

I am not a big fan of running a lot of trailing edge cup on our boats because

it kills RPM. If you run the older series propellers and are happy with their

performance then I would use what works well on your set ups. Sometimes

you need to lower the strut depth a little more with the new series propellers

because of less transom lift. With my GT-21 the 1815 works very well in heat

race trim. I believe the set up with some of the 21-Hydros may need more

adjustments to let these higher rake propellers do their job they were designed

to do. Nothing wrong with learning about propellers and how they work. Just have

a good pitch gauge so you can measure them accurately.

Have Fun Testing,
