Hydrofoil Stabilizer for 35-300 HP Engines by SE Sport 300

Amazon Customer: This hydrofoil made great improvements to my boat in getting up on plane and lessening steering wander back and forth. Installed on a 4.3 Mercruiser and I didn't lose any speed. I changed the screws from Phillips head to hex socket head to better ensure tightness.

WarmInWinter: I wondered if this would actually help my boat plane. It does.
My 19' Campion inboard has a 5.7L and a big rear gas tank so it definitely is heavy in back and annoyingly, it wouldn't plane when we were trying to pull kneeboarders or tubers at the most appropriate speed. The bow was in the air and it was just dragging along. Very annoying.
But with the Hydrofoil it now planes at that same speed, I can pull back on the throttle, get the nose down and actually see where Im going, while using a lot less gas to pull.
An added benefit that I hadn't thought of before we bought is that the Hydrofoil covers the prop so when kids are loading or unloading from the boat they have more protection and tow ropes are also being kept above and away from the prop.
Overall a decent performance and safety improvement and well worth the money.

Kenny: I put this on a 20’ Sea Ray deck boat with a 5.0 liter, gets out of the hole way quicker and I’m up on plane about 4 to 5 mph slower. Great cruising speed.

Johnathon Welch: Bought this for my 1998 40hp Mercury it completely made a world of difference in how my boat rides, and improved my steering! Definitely a good investment and came with all hardware! Highly recommend

M. HavrelockM. Havrelock: Installed on a 2005 Glastron GX205 w/ 5.0 270HP engine. Taking it out tomorrow so I will see if I notice any changes in operation and holeshot and will update here. Hoping it eliminates or greatly improves the big “squat” when launching from a stop.

Pros:
1) Template to mark holes for drilling was perfect.
2) Has a nice look to it. I need to repaint my outboard now!

Cons: 1) had to go buy longer stainless steel hardware as the included screws I could barely get on thread rotation on the nuts without using the rubber washers. I purchased actual stainless bolts (not Phillips screws as you can’t get that “umph” to tighten). I also purchased stainless metal washers to go on the bottom of the rubber washers and stainless lock washers. I am NOW confident this is sturdy and not going anywhere. Just need to use my cutoff wheel to trim the excess on the bolts.

2) part is plastic, I didn’t even think about what it was made out of. Idk how long it will last out here in AZ as plastic gets brittle with excessive heat so I’m already questioning the longevity of it but for $75 or whatever it was we shall see!
