[QUOTE="TheLastCall, post: 454915, member: 23099"] Is it getting up on plane? Once up on plane your motor will have less resistance and will climb in rpm. Hydrofoils are an option if you can get it to plane. My personal experience is with a Princecraft Yukon 15 and a mercury 4stroke 15hp. It would plane without hydrofoils if I had minimal weight in the boat it would take a while for the bow to come back down. Now with hydrofoils, same conditions ( minimal weigh ) I get close no bow rise and it jumps on plane in 1 boat length. Once on plane I can run at half throttle and keep it on plane with minimal decrease in speed. Sent from my iPad using Tapatalk [/QUOTE]
