fishingfourfun Posted July 14, 2007 Posted July 14, 2007 I was wondering if anyone has used a hydrofoil for a 9.9 hp motor. My 14 ft boat has a terrible time getting on plane and then it begins to porpoise very badly. Any help would be greatly appreciated! Name of hydrofoil would be helpful. Quote
Josh VanderMeer Posted July 14, 2007 Posted July 14, 2007 my 14 V w/ 9.9 used to poirpose with just me on it when i was at slower speeds ... but i just put the trim ALL the way down on my motor and it doesn't do it n e more... and it gets on a plane easier hope that helps so how :-/ Quote
kybassangler Posted July 15, 2007 Posted July 15, 2007 It will help getting one. They sell 'em at the basspro for the smaller motors. You'll hafta drill four holes and bolt it on. Sting Ray XP Junior cost you 50 bucks plus shipping. Quote
HPBB Posted July 15, 2007 Posted July 15, 2007 my 14 foot starcraft with a 15 merc will not plane without them. I bought the dolefinns, best thing I bought. well worth the $30 or so $$$ Quote
paleo Posted July 17, 2007 Posted July 17, 2007 i dont know on a small motor but iknow that it made a huge difference on my 125 on my 22ft pontoon that was the best 65 dollars i spent on that boat it completly fixed bow lift know it rides nice and level also 2mile an hour faster Quote
fishingfourfun Posted July 18, 2007 Author Posted July 18, 2007 Does putting on a hydrofoil void the motor warranty? Quote
paleo Posted July 18, 2007 Posted July 18, 2007 warranty is something not be taken lightly i would defently check with manufacturer about that mine is old so it did not matter Quote
fish-fighting-illini Posted July 18, 2007 Posted July 18, 2007 Don't most motors have some sort of pin mechanism for adjusting a trim type effect buit into them? Mine is an old 9.9 and has it. Changing the pin position helps with cavitation a bunch. I imagine it could help with planing as well. Quote
HPBB Posted July 18, 2007 Posted July 18, 2007 Don't most motors have some sort of pin mechanism for adjusting a trim type effect buit into them? yes, most if not all I know of do, but sometimes that is not enough and the motor just need some lift and the hydro's do that. Like I said on my 14 footer with a 15merc it just wouldn't plane. set the motor all the way down and it would plow through the water set it a spot higher and it would stick the bow straight up. there was no good spot. However, after putting the hydros on it it would plane out very easy at different pin hights. Since the boat will plane out now I could set the motor at a higher trim spot so I could get some more speed out of it. Sometimes the trim angle of the motor is all it need sometimes its not. my 17'6" the hydros did nothing to it. It planed just the same Quote
