Re: Towables
i put a hydro foil on my last boat it was a 90 hp v4 and i noticed a differnce, turning seemed like the boat didnt rock back and furth so much and it made the prop run at a lower rpm. as for what the companies tell you that they increase fuel, no they dont, or increase hp and or/speed, again false felt like i was going faster but accually since my rpms droped i lost about .5-1 mph. to the trim part, keep outdrive all the way down more power if your cruising fine trim it up, but for sports or heavy loads best to just keep it all the way down.
looking back the $70 i spent on that hydro foil was a big waste, kind of like putting a spoiler on a handa, wont be usefull untill you hit the 100+ mph which is illegal in the USA.
