Sport Marine SE Sport SE400 Hydro Foil Gray for 40 HP and Up 74644

I had this exact Hydro Foil on a former boat and it greatly improved the boat getting on plane and how it handled while going at slower speeds like in a no wake zone. I recently purchased another boat and it doesn't have trim tabs like my primary boat has now. I considered putting trim tabs on the new boat but then I remembered how much this improved my old boat so I went with one. These are a great buy, the no drill application is pretty straight forward and easy to install and it fits great. I am happy with the quality and it looks great.

Purchased for a Worldcat 255DC with 150 Yamahas. These are easy to install at the sandbar using the supplied hardware, a 7/16" wrench and Phillips screwdriver. I was able to baseline the boats performance prior to installation, but I have not re-evaluated post installation data yet. These were installed when the boat was at full fuel, and an excess of gear and people aboard. One thing I can say for sure though is that it has gotten the boats tendency to porpoise under control, which was the main reason I wanted to install them. They work. Up on plane at lower RPMs and definitely a smoother ride and less fiddling with the trim control. I've been checking the torque on the nuts and have re-tightened a couple times. I will drill through mount these soon since they are of noticeable benefit.

I bought this device to improve deficiencies with the design of my Chaparral H2O 180. Mostly, it worked. This boat has an overly heavy stern that causes it to porpoise and it requires a fairly high speed to stay on plane. The hydro foil caused the boat to ride higher in the water at lower speeds. The boat stayed on plane at 18 mph rather than 24 mph. The porpoising problem was much improved. The boat cruised at higher speeds for a given RPM, which I suspect indicates improved fuel economy. The most surprising change was the improved ride in rough water. This was an unexpected bonus. Alas, there is no free lunch. My top end speed decreased from 51 mph to 48 mph with the device installed. I consider this sacrifice more than worth it. "Before and after" tests were done on the same day with the same conditions and load and speeds were measured by phone GPS rather than the grossly inaccurate boat speedometer. It was almost trivial to install the device at the boat ramp with only a single wrench and screwdriver. The whole process took maybe 5 minutes.

This product now makes my boat useable. It's not a miracle but it makes the boat do what it is supposed to do -- get on plane and full speed quickly. I used to have to stand toward the front of the boat and hold the steering wheel behind me to get it on plane. If the bilge was full of water I had to wait until it was all drained to get going. Last week I was able to get up to full speed right away even with the bilge full of water and could run while pumping. I had 3 adults and 1 child yesterday with no problems. And it is super easy to install. I installed it in less than an hour -- by myself while the boat was in the water! If I did it on land with an assistant it would take about 10 minutes but I had to be careful not to drop any of the nuts/bolts in the water. It might take a few MPH off the top but I don't care as long as I can go. And it porpoises right away if I trim it up a little. I have it on a Mercury 60 HP bigfoot motor on a 16 foot Bayliner Element deck boat. I highly recommend it.

Se400 sport arrived on time, since my boat is in storage still I dont know if I will have an issue with install or planning. The product is as described but won't know until installed and tested. It will be going on 115hp mercury out board. will update in may or June. (Update)July 7th, 19. So the install was easy, however I needed larger bolts so I had to go and buy 2 large bolts, although I couldnt find the same exact ones it still worked. Now i was on the lake yesterday and i must say that this product did not plane as fast as my previous whale fin (no where close)(it is shorter than my original one) how ever I think it did take some shaper turns and was slightly faster after it started plaining. I believe it's designed for smaller/lighter boats? Mine is a 16 1/2foot with merc115hp outboard long shaft. Over all I'm just happy it was able to replace my older broken tail fin.

Does what I expected. Boat planes much quicker. Easy to mount. I've been out several times and feels solid. Did lose about 3mph on top speed but well worth the benefits of having it. The shipping got a bit wierd as I was told it was delivered by one company but it wasn't. It showed up a day later from another shipper.

2/26/2020 Bought this because I was having issues with my boat leaning left and taking a while to plane out in very moderate chop. 1988 16ft V-hull Sea nymph Aluminum with an Evinrude 1984 70hp and an SST prop I know it's very uncommon for there to be such a major difference in the way a boat rides but not only does my boat plane faster, it doesn't seem like the bow rises at all. Motor is trimmed all the way down in moderate chop on the Florida intracoastal. I did sacrifice 1mph but the ride has improved dramatically. Steering is much more responsive and there is absolutely no lean on the boat when riding straight regardless of speed. I went with the bolt on method for the front end of the hydrofoil and the clamps in the back because there was no space for the bolts to run through the cav plate. Also used locktite to insure nothing will fall out. The difference is night and day. I would highly recommend this if you're in a similar situation that I was in. Update 9/9/2021 The rubber clamp parts have rotted away and had to be replaced about 6 months ago. Not too surprised about that but otherwise, its still doing a great job even after many trips.

Don’t buy this if you have a 115 mercury. I installed it with the no drill option just checking to see if it would help. It did not and after one trip it cracked my aeration plate on the lower unit. Save yourself some time and money. Don’t buy this piece of crap.

I put this on a 75 hp merc that is on a 1625 aluminum harbercraft boat. I gained 15 km pr hour when trimmed up. very pleased and impressed

I havnt owned it very long but I went with the drill mount method and it took about 30 min start to finish. I personally love the way it looks. It feels sturdy so I dont have concerns that it is going to fall off. It's on a 16' bayliner capri with a 90hp outboard 2 stroke motor with a 13" propeller with a 19deg pitch Loaded down with 3 adults and camping gear it still takes a bit to get up to speed but thats just because the motor is on the small side other then that it feels great and solid while up on the plane. If it's just me in the boat it pops out of the water, feels rock solid and I have certainly gained a high top speed. For the price I totally recomend and I plan on buying the se200 to try on my tin boat with a 9.9hp

Dopo una lunga riflessione su l'installazione dei flap ho optato per questa soluzione. Sono possessore di una Beneteau Flyer 5.5 Sundeck con Suzuki 100, la barca è molto pesante (1200kg a secco con motore) pertanto vista la non eccessiva potenza installata tende ad impopparsi e faticare ad entrare in planata. Ho acquistato questa pinna sperando di risolvere i miei problemi, di seguito elenco i pro ed i contro: PRO - la planata è leggermente migliorata, la barca entra in planata leggermente prima, o meglio più velocemente, anche se speravo si notasse molto di più la differenza, però direi comunque bene. - una cosa che mi ha sorpreso non poco è come la navigazione è cambiata in presenza di onde o mare mosso, mentre prima la barca tendeva ad alzare molto la prua al momento dell'uscita dell'onda con relativo tonfo quando ricadeva (come tutte le barche), adesso la barca affronta le onde in maniera mooooolto dolce, sembra quasi che la pinna sostenga la poppa al momento dell'onda evitando di alzare troppo la prua, risultato una navigazione in presenza di mare mosso mooooolto più dolce e di conseguenza la velocità può essere più sostenuta senza dare e togliere gas continuamente. - La pinna permette di regolare meglio il trim in quanto tende a proteggere l'elica e quindi evitare spiacevoli cavitazioni, o almeno limitarle in caso di motore alto, infatti sto pensando di alzare il motore di 1 foro. - Il prezzo - La facilità di installazione (mezz'ora con barca in acqua), se possibile consiglio di installarla con barca a terra. CONTRO - La velocità, a partire dalla planata fino alla massima, quindi dai 4000 ai 6000 giri ho perso circa 1,5/2km/h, diciamo 1 nodo. Sinceramente è più che accettabile visti i PRO. - Speravo che i giri minimi per la planata diminuissero invece non ho visto grosse differenza, sotto i 4000 giri la barca perde la planata come succedeva prima. Visti i pro ed i contro consiglio sicuramente l'acquisto! Vale tutti i soldi spesi, in oltre aggiungo che il sistema di installazione senza fori sembra reggere molto bene senza rovinare la pinna originale come fa qualche pinna concorrente.

Great performance but I had to cut a small piece to fit my 50hp honda

Good quality and easy to fit. Did help getting on the plane
