Good morning Pat,

Velox worked very well for me when I was in the Bahamas, but in San Juan, PTortola and Sint Maarten it doesn’t work…
I think it depends how much barnacles there will be or may be the water temperature…

So if you were able to get 3000 then I would bet your issue is barnacle build up.
When I was in San Juan I did an engine run (at the dock) and was shocked not to be able to exceed 1350 rpm… I dove and saw lots of barnacles on the prop, I cleaned it, then was able to go back to 2200 rpm.

Joel then ave the trick to put a black plastic bag on the propeller.

Sincerely, Alexandre

Alexandre, That is not my issue, I failed to
say that I have always been able to top out at about 3000 or
3100 rpm and about 8.3 kts. I had put Velux prop anti foul
on my prop last year and three months later I could not
believe how many barnacles I had . The company never
responded to my questions . I surmised that if it works , it
is not meant for fresh or brackish water. I know some bottom
paint is not to be used in fresh water.

Good morning Pat,

It is a common problem that some of us have,

In my case, even with a rebuilt propeller, new turbo and
clean hull I was not able to exceed 2350 rpm.

Even thought my boat is heavier than recommended, I believe
it is because of the oversize propeller, Kent on Kristy re
pitched his and can now go 2800 rpm.

This summer I have not been able to

motor above 2200 rpm , but in neutral I can go right up

3000 . I have not been able to dive on the prop to see if

is fouled do to an injury. If I had a problem with fuel

turbo etc. would I be able to get up to 3000 in neutral

not in gear ? Or does this indicate just a fouled

prop. Thanks,PatSM#123
