SE Sport 300 Hydrofoil, fits 35 hp - 300 hp engines

Installed on a Mercruiser 5.0 with alpha 1 gen 2 outdrive to solve slow planing. The boat is a 20' Monterey Montura. Plenty of power, but the boat loaded just has a stern heavy situation. I don't allow the kids up front when the boat is on plane and the water is choppy so to the big couch in the back they go, hence the always stern heavy. Boat would plane out nice at 18-20 mph but that's a tad fast for kids learning to knee board etc. With the SE300 it made all the difference in the world. Now it has very little now lift and full plane is achieved at 14-15 MPH. Much more comfortable for everyone in the boat, and I can safely see over the bow while seated.Install is straight forward, follow instructions and center the foil and mark your holes carefully before you drill. I also chamfered the holes once drilled to relieve any chips or micro cracks from drilling. Then treat the holes with self etching primer and small paint brush. I used large area stainless steel washers (not supplied) on the bottom where the hardware contacted the cav plate. This spreads the load of the screw over a larger area and will prevent cracks or damage to the cav plate.

Great hydroplane and easy to install. Install tip - put some grease on the rubber spacers to hold them in place while installing.

2021 Lund angler 50hp motor. Been using for about a year. Had no complaints about the boat in the first place, just had positive experiences with this style hydrofoil in the past. I do 50/50 shallow rivers to big lakes. Thing works great. Got 2mph top end stock prop @ 6k rpm (28mph to30mph). Once you get the feel for the trim, the nose really doesn’t rise at all at take off. Very nice for shallow rivers. Planes faster and once you get on plane you can slow back down a little and remain there. I can turn sharper without cavitation (still cavitates, not as quickly). This product is boat specific. Different experience on my old 16’ bass tracker, and a 20’ pontoon. Still good results but no top end gain with tracker or pontoon. I want to add I didn’t want to drill through the node so I shaved the hydrofoils opening wider so it slipped further back. Mounting holes now miss the node. Also, if the hydrofoil is level with the cavitation plate it doesn’t work as well. Putting some nylon washers in the front of the foil to angle the rear of it down had better results. Obviously, too much angle slows the boat down. You’d think they’d mention something about angling the foil to fit your needs.

Its been on my 18 ft bay boat work great gets on plain quick

This is a well built, heavy duty item. Really easy to install and works well.

I had one these on my outboard for 20 yrs, held up to years of abuse, bumping into rocks, used as a step, Arizona hot summers. I originally bought it for extra lift and stability in turning. My motor is only 50hp so speed is not a factor. I don't know what plastic resin they used to make it but it held up. I hope to get same performance out of this new one.1998 Yamaha f50tlrx. Boat 2000 G3 MV175. Max speed 30mph. Prop Solas 4 blade alum 12pitch.

Installed this on my 20’ bowrider (Sea Ray 205 Sport) and I’m now planed out effortlessly at low RPMs. I don’t even have to stand when maneuvering inside a cove or marina anymore. It’s so good I might change out my prop for higher top end seeing as my hole shot is so fast now. I was only able to mount using 3 bolts due to lower unit damage but I had this on all year (2024) and it’s solid as a rock.
