Wow. With a Drag 5 30p I was only able to get 88 mph

I am not technical when it comes to setup and propping. This was the recommendation i received for achieving good top end. There is anothe Lib 21 here running 102 with the same setup. The key is one person and low fuel. With decent fuel load and a couple others on board that speed is not possible.

Yes, I understand. Are you near the red line at that speed? 6400?

I think 5 blades is maybe too much for a 300xs.

No, I'm below 6000.

Updated props tested:

With all gear and just myself here's what I have-

Merc Trophy Plus 28p 6100 rpm @ 85 mph
Merc Lightning ET 30p 5800 rpm @ 93 mph
Drag 5 30p 5700 rpm @ 88 mph
Ron Hill Signature Eagle 28p 6300 @ 90
Promax 29p 5800 @ 92

The results are all over the board. The Promax has the best "feel" I think but the Signature Eagle was very smooth too.

How bout the eagle with few tweaks, mite get u to 95 range but keep gud rpm?

3 blade lightning et?

Suprised you couldnt pull more rpm out of the 29p promax.

Yes I know. It's been worked and it hooks up good. The Lightning IS a 3 blade. The Promax is a 4 blade.

Wildman told me every 200 pounds will cost almost 5 mph. So I guess if I got rid of the second battery, the beach umbrella, ran the oil down to 2 or 3 quarts, ran the gas down to 5 gallons, didn't eat or drink and evacuated before trying again I might get to 98...

Hell I'm 205... if you ever met Wildman he's maybe 165 soaking wet.

I like the way the boat runs at 90. I'm glad he talked me in to getting one
