Hydrofoil

[harmanoff]

I am in search of a hydrofoil, I have a 2002 Mercury 60hp Bigfoot ELPTO. I need a hydrofoil for it. Got my prop and WOT rpm figured out but now I go to fast and once I get it to 5200rpm my boat starts to porpoise. Any thoughts

Drop down your trim. The goofy tail is not the answer

How so? Had it on an older boat with a 50hp Yamaha and it stopped the porpoising. I can get another 200-300 rpm and get another 2 mph out of her!
