Does anyone have any insight on these things? Put 'em on the cavitation plate and you get on plane quicker is my understanding. Some say your top speeed is a bit lower. I've got a 17ft Crestliner Fishawk w/ a 90hp Yamaha. Are they [PoorWordUsage] or useful? Thanks

I have one on my boat 05 fishhawk 17.5 90 4 stroke Johnson. As stated before you lose speed maybe 5mph. I can get to plane at about 1/3 of my speed, and hardly no cavitation when turning on a dime. They only help alot if you have a loaded boat or towing and maybe when planed out.

If you wanted my two cents it's not worth the money, I am sure I payed $100. bucks for it. Good Luck

Some boats just perform better with them even if they have the max HP hanging on the back. Skeeters are one that comes to mind and it's almost a given that one needs to be installed.

I've been thinking of putting one on my tiller (which has the max allowable HP) just because of the weight balance of the boat and the speed required to keep on plane. Lowering the on-plane speed would come in handy when running rougher waters among other things.

If you're having issues getting or staying on plane it might be an option for you compared to re-powering.

Agree 100%. One of my buddies has a Skeeter 1880 rated for a 200hp and he has a 200 HPDI on there. Great motor and the boat ran really well and he did some prop testing to get the best prop --- then he put the hydrofoil on and it made a noticable improvement for him.

I've got another buddy who bought a Triton that had been used for a year on the PWT -- the PWT pro had put a hydrofoil on that boat too.

My main problem is that my boat pulls hard to the right. If I let go of the wheel at full throttle it would be dangerous. My skeg is bent to the right from a sunken Canadian island. I also realized my trim tab/ anode was missing as well. I replaced it the other day, and if I straighten the skeg I would think I would have a better ride. The hydrofoil addresses diffferent issues it looks like. Thanks for the info.

They work fantastic and have helped ton's of Boaters with a much better hole-shot and contrary to popular opinion they have also helped a few with top end speed gains as advertised.. smile

I hated drilling holes in my 115 Merc. But it was worth it back in my Skiing days behind the 16 Baja for the insane hole-shot the Hydra-foil provided for our water sports.

I'm not maxed out on HP so it helps get on plane faster but with proper trimming that isn't a problem.

Here is where I like the foil. I can reduce my speed and still keep on plane where as without the foil the boat would fall off plane.

That comes in handy when I'm going though traffic areas where I want to reduce speed, I can do that a ridiculously low speed but still be on plane. Less wake and I don't have to punch it to get back on plane when I've passed those boats.

Its also nice when searching for structure to stay on plane but at a slower speed.

That's why I bought one too. Staying on plane at a low speed is very helpful when you are alone driving a tiller through a log infested river at night. smile

It did drop my top speed by a couple mphs though.

      Problems with Yetti

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      By Wanderer · Posted

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      Problems with Yetti

      By rundrave · Posted

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
