Rodman, check it out- I made "Active User" status. Woohoo! This cold winter has stepped up my posting a lot. I will be much more scarce this spring and summer.

I found the info that I was looking for on blade tip to hull clearance. It should be approximatly 15% of the prop diameter. This means that on a 14" prop you should have 2.1" of clearance. You would have to be turning a 13" prop on an F-26 (mine any way) to achieve this. I have closer to 1 3/4" clearance on my 14" diameter prop and noise from vibration isn't really a problem.

Right - 15% - as I said earlier ... less space causes turbulence (not a terrible issue until cavitation sets in at the extreme), but it will cause more noise.

Not sure how much room the 25 & 26 have ... can't imagine a 16" will fit well ...

Foofer's 454 is testing the limit with the space that Trojans seem to have ... have to add pitch to make it up.

I run 17x20's for the same reason.

Well I tried the 14x12 LH prop Roy had it would not plain out at all. So I am not sure what to try now. I did win a 14x10 1/2 on ebay. I am going to try that one soon as it comes in.

Clean and smooth bottom? Very important.

Rodman,

Did you get your new prop on yet? Wowzer is concerned that your bottom isn't as clean as it should be

Maybe Wowzer wants to help him clean his bottom.

Did you spend any time on the bottom? It will make all the difference in the world.
