I have a combo alluminum hydrofoil trolling plate . I cant say for sure wether the hydrofoil makes a big difference. But the trolling plate when in use is awsome. I have a 17 ft lund prosport with a 115 yamaha that i can slow down to less than 1 mph with the plate. 3 mph without the plate. Top speed is 41 mph. Hope that is a help Sent from my SM-G930W8 using Lake Ontario United mobile app
