I’ve used the SE Sport 300 hydrofoil fin on my Mercury 115 (22’ pontoon) for 13 years. 100% satisfied. These are a must for any pontoon 75hp and up. Completely eliminated any prop blowout from cavitation. Without it I had to progressively accelerate, but with it I can bury the throttle from a stand still and get a nice whole shot. Steering is more precise, thrust is focused better, and you get no porpoising. WELL WORTH THE MONEY for Pontoon boats!
Can I ask why you address the correct propeller before adding a hydrofoil, wouldn't adding the hydrofoil first allow for a different choice in propeller, only asking because I need to change both and was going to put a hydrofoil on first.
Absolutely. It gets the back of your boat out of the water sooner and as he stated keeps your transom out of the water at slower speeds. The less water your boat is pushing the less wake it creates. Fuel efficiency is also improved and stress on your engine is actually relieved when using a foil.
I have an inflatable boat (Aquaparx 330) with a 4hp engine. Enough power to sail a little with the kids, but I’m not able to give it full throttle without it makes air “vacuum” around itself. Could a small hydrofoil help with that?
Any combo recommendations for a 21ft Maxum v8 bow rider? We usually have a close to full boat (9). Within reason we don’t much care about top speed. We are looking to get up on plane a little quicker with the extra weight. Thank you in advance.
great video thank you. could you please tell me if hydrofoil would be beneficial for my 6hp 4stroke outboard? its on a 10ft inflatable dinghy. some say hydrofoils are only good for 10+ hp outboads anything smaller is a waste of money and will slow down the boat.
Hello! I would say that it is beneficial to your application if you gets the correct size hydrofoil. They do make much smaller ones for 40HP motors and under. They are the Attwood JR-1 series. We normally have them in stock but we are sold out right now at the end of our season. Andreas has ordered more for the next booking order, so we will have them in stock next spring. Feel free to give us a call if you'd like to discuss or have any other questions. Or call us in the spring if you're interested in pricing/ordering. 1-866-535-1004 - Julie, Parts Department
Hi! Crosshair! Have you bought the hydrofoil for your 6hp boat ? I've the same power / size boat and I cant find anyone who can share that expirence! Thanks!
@@ruifrancisco8777 hi after extensive research, the conclusion is that the smaller outboards don't benefit from hydrofoils because they aren't powerful enough and even if you install one you won't notice improvement. Hydrofoils are good for 10hp or higher outboards only. I sold my 6hp and bought a 10hp engine. i didn't buy a hydrofoil for it, maybe ill experiment this summer. good luck
Yes, a hydrofoil will greatly help a pontoon/tritoon. We are finding that the center forward weight of the people on the pontoon boat is affecting the height of the propeller and its proximity to the surface. This effect of the over centered weight on the boat is causing the propeller to cavitate and cause poor running issues. So, the best fix is to run a stainless steel prop (cause it's 5x stronger than an aluminum prop) and a hydrofoil to help stop the stainless steel propeller from sucking surface air (cavitation). Also, the hydrofoil gives the motor much needed support to help the motor not be so manipulated by the pontoon boat's over centered weight of where the passengers are seated (basically, any persons in front of the driver's seat). Having the hydrofoil bolted to the cavitation plate of the motor helps the motor correct the effects that the hull is having on the propeller. Thanks so much for watching and for your question! Please feel free to call us if you're ever in need of parts or technical assistance! 1-866-535-1004 - Andreas
Thanks for the info. It's not so bad with just two of us but with 3-4 passengers in the bow loungers, it's almost impossible to trim up; I just get ventilation if I try. I'm not looking to really add performance; I would have purchased a larger engine if that were the case. But better handling and trim capability would be good. I did purchase a Spitfire four-blade over the winter and will be swapping out the OEM prop in May. I will see what differences I notice at that time and then I may take your advice. I had a Stingray and four-blade prop on my 2006 215 5.0 Bayliner and it made a huge difference in handling. I just didn't know if I could compare that to tritoon use. I have your website saved and will email you over the summer. Cheers.
@@megapix-x51 THE ULTIMATE TEST!! So, I understand that you were not looking for huge performance as you say or you would have purchased a larger engine...BUT.... You did purchase "BALD TIRES." (THAT ALUMINUM PROP YOU PURCHASED, I WOULD RETURN AND TAKE THE MONEY FROM THAT PURCHASE AND PUT IT INTO ANY 3 BLADE STAINLESS STEEL. Just saying.) The ultimate test is to take your boat at 25 mph and do 3 huge circles and then cut a tight turn and go thru the middle of your hurricane that you just made. You will notice that any three or four blade ALUMINUM prop on any boat combination will stop the boat and cavitate. Basically, spin out and stop the boat dead. (So it's like bald tires in the middle of winter on ice. Once you get going they're OK, much like an aluminum prop. But, once you turn SHARPLY and need any traction and grip, the aluminum flexes and spins out like bald tires. The stainless steel, which is 5x stronger, will not. So you get better thrust, better fuel economy, and more family fun (especially tubing cause now you can do a more controlled tight turn and get to those waves that you made in the middle of the circle). I've seen people zig zag, do S turns, anything to catch a wave for the people tubing to make it more fun and there is nothing like the example I keep repeating because so many boaters never knew it was possible to "catch the ultimate wave." One last thought. Is your 115hp Mercury engine equipped with the Pro XS gear case, or the standard one? This is also cause for concern because the smaller standard gearcase has less surface area for "push" contact with the water and is running a smaller diameter prop so it is less effective in trim of the bow as you first described. By all means, call me any time. I'd love to chat props with you. 1-866-535-1004 Best Regards, Andreas
When used with a SST prop the hydrofoil helps the propeller not cavitate by grabbing surface air. If your using an aluminum prop, nothing helps it corner, Our parts expert Andreas calls "aluminum props bald tires on a limo on a skating in the middle of winter" If you want a further explanation give our parts team a call!! 780-732-1004
It would probably be the Attwood two-piece hydrofoil or the Starfire Junior. We don't have either in stock at the moment, but they will be coming in in the spring:) - Julie Recreational Power Sports

Thank you for the information that was really helpful
It does slow the top end a little, but most ppl don't run the top end most of the time
how do these hydrofoils compare to Uncle Norm's Orca Fin?
Does it helps with reducing wake?
Absolutely. It gets the back of your boat out of the water sooner and as he stated keeps your transom out of the water at slower speeds. The less water your boat is pushing the less wake it creates. Fuel efficiency is also improved and stress on your engine is actually relieved when using a foil.

Have you ever heard of installation and use for a tritoon to help lift the bow up for better performance (115hp)?

How does the hydrofoil affect the boats cornering?
When used with a SST prop the hydrofoil helps the propeller not cavitate by grabbing surface air.
If your using an aluminum prop, nothing helps it corner, Our parts expert Andreas calls "aluminum props bald tires on a limo on a skating in the middle of winter"

It tracks better without cavitation. On rails.
It reduces the chance of cavitation while turning and grips better; “drifts” less.
Do you have a suggestion for a hydrofoil for my honda 10hp fourstroke?
It would probably be the Attwood two-piece hydrofoil or the Starfire Junior. We don't have either in stock at the moment, but they will be coming in in the spring:)
