"Wrench,Guy and John
I run an international commercial grade antifoul on my hull which is rated at 5 year recoat and it works wonders but it has enough copper in it to just about power all my electronics and so i keep it well away from the outdrives.
What I do, is try a different antifoul on the transom and outdrives everytime, with my own bit of chemistry thrown in as well.
After I use one application of straight antifoul as a control, the next time I coat it I will use Chillie powder and the time after that I will use glysophate as well.
I then compare notes, so far the best result I have from trying 3 different antifouls with varying aditives is the International interspeed 2000 by itself, (I thought it was micron 2000)when I next recoat the legs and transom I will add the Chillie powder and after that, the Glysophate to the interspeed but so far I am up to 5 months of minor growth in water temps ranging from 16 to 21 degree C.
I have to agree with your reserch Wrench the Chillie powder works wonders and the hotter the better, I so far have up to about a 30% increase in the life of my antifoulings effectivness when I add the Chillies.
If I can get my antifoul life expectancy on the legs up to around 8 months that will make life easy and save me quite a bit of money.
