Hello People...
yesterday i bought a paid of hydrofoils to be fitted on my 40hp Tohatsu, did anyone ever try a similar setup before i start drilling the cavitation plate?
Manufacturer claims a much smoother ride, getting on the plane in half the time, staying on the plane at lower speed, 20% less fuel and a an increase in speed.
I would appreciate your feedback.....
I had them installed on my 15hp Evenrude and they worked very well :)
i have installed hydrofoils about a year ago on my motor and i feel it planes better , be sure they are appropriate size for your motor and also use DUROLAC anti corrosion liquid in the holes you drill
Hi big what were the benefits after installing them ?
boat keeps on the plane at lower speed, by boat was not a planing hull and managed to plane with them
Thankx big I have a set but I am a little afraid to drill the outboard becouse of the corrosion
Hmm... these Hydrofoils got my interest and I'm willing to give them a try.. anybody knows where I can get one for 2 stroke Yamaha 9.9? (mill bluni)... even if they are used no prob as long as in good condition.
They dont cost a lot about 25euro if I'm not mistaken . Caruana Marine center was the last shop I saw them .

Thanks ggantno1 ! :) ..Will let you all know how it goes before/after, as soon as I have them fitted ;)
ok thankx my only worry is drilling the outboard and risking that corrosion starts its way up
ggantno1 - There are hydrofoils on the market which you do not have to drill the outboard for. They fasten themselves with types of clamps etc. However they are more expensive.
Hope it helps!
How much more pls?
I do not know cause it varies from model to model but i dont know local prices because i searched on the internet for one. I would like to attach one but will not risk drilling holes in the motor especially if there are alternatives!
This is the site that offers hydrofoils where you do not need to drill the anti cavitation plate. Read a couple of reviews where the hydeofoil simply fell off, and installing them seems to be a bit tricky too.

I think i am going to go ahead and fit the Easterner hydrofoils i purchased from Mecca.... Then will see how it all goes. So far i have not heard anyone commenting negatively so i am assuming that they are good
These Stingray hydrofoils seem interesting although I am sceptical on how they hold on tight. Reviews are not very encouraging. I was viewing the Permatrim for some time now but am not too much inclined to having to drill through the cavitation plate.

These are the ones i bought, it seems that they reallly make a difference especially on small boats.
Not that I know much about these things but if it were my call I would definitely not drill through the plate of a 4000 or 5000 euro outboard to fit 16 sterling worth of hydrofoil!
Nice dilemma ehh guys??
come on just drill it! you are speaking like your going to drill in the palm of your hand lol. use some anti corrosion liquid and that's it
Whats the big deal about drilling the outboard ???????
Drill, use anti corrosion liquid (brunox is very good) and if needs be mask out the area where the hyds will be attatched, sand down and re spray with suitable paint...... and you will surely not have any corrosion problems. To be extra cautionate apply marine grease to the holes aswell before fastening the Bolds.
TEFGEL is the best, you can buy it from dagata marine , or else DUROLAC from gauci borda, they are liquids made to prevent corrosion between dissimilar metals . what happens is that stainless steel in contact with aluminum will create galvanic erosion and sea water will work as a conductor, the anti corrosion liquid will isolate the dissimilar metals , be sure to NOT USE COPPER PASTE on aluminum
These are made of plastic I assume!
I had used iron bolds on mine since iron does not create any reactions with aluminium
baghira the bolts to hold it in place are plastic too ? lol
bigboy good move to use steel, but galvanized bolts are not good for the job.
okies... I seee
If hydrofoils improve performance significantly, why don't outboard manufacturers simply design their outboards with a bigger cavitation plate in the first place ? Just wondering... :-\
I have fitted a pair on my Tohatsu 30hp 4 stroke and made a big difference. It planes sooner than before it stays on planes at lower speed, it stabilizes the boat on plane better. I fully recommend them. I have on my Albatross 390 with Tohatsu 30hp 4 st.
What brand are the foils u installed? U got them from Mecca? As i believe that the shape the foil has make a huge difference
Lalizas LZ-Hydrofoil Gullwing Stabilizing System , these are very good over 50hp
