Common Questions

For Both SE Sport Models





1.  "What is the warranty on the SE Sport?"

SE Sport carries a lifetime limited warranty. Specifics regarding the warranty can be found on the packaging.


2.  "What size outdrive will it fit?"

All sizes that have a cavitation plate larger than 5 inches wide, usually 40 horse power and up. Because the mounting holes on the SE Sport 300 are 4 inches apart, right to left (center to center), a 5 inch or smaller cavitation plate leaves less than inch of metal from hole to the edge of the plate. The SE Sport 200 is recommended for cavitation plates 5 inches or less.


3.  "Will the SE 300 fit Volvo outdrives?"

The older Volvo SX with the single non-exhaust cavitation plate requires 1-1/2" bolts (not included)for the rear holes. Volvos 280, 290, DPS, DPH, and the newer SX models with the exhaust through the cavitation plate require four 2-1/2" bolts and 1" to 1-1/4" fender washers with the bolts and fender washers on the bottom plate and the steel washers and lock nuts on top. Not recommended for Volvo Ocean Series XDP sterndrives.

4.  "Will the SE Sport 300 fit my Honda Outboard?"


Many Honda outboards are made with a center cavitation plate ridge. Some Hondas will require a slight cut or bigger notch in the "yoke" area of the foil. This is necessary to give 1/2" spacing between the rear holes to be drilled and the end of the cavitation plate. Cutting a notch can easily be handled with a small saw or grinder and will not affect the durability or warranty of the SE Sport.


5.  "Is there enough clearance to mount the SE Sport 300s on dual outboards?"

Yes. Because of its narrow profile, you can easily fit two side by side.


6.  "What are the dimensions of the SE Sport 300?"

17 inches wide, 14 inches nose to tail. You may want to refer to our installation page for further details.


7.  "My cavitation plate has a large nut which interferes with the SE Sport sitting down flat." 

With the added thickness of polypropylene plastic in the main body of the hydrofoil, you may cut or chisel out an area to accommodate the nut. This will not affect the durability or warranty of the SE Sport


8.  "Will the SE Sport cut down on my top-end speed?"

Independent tests have shown the SE Sport to be the fastest foil on the market. Trailer Boats Magazine rates the SE Sport fastest in 0 to 30 and top end speed, and Bass and Walleye Boats Magazine rates SE Sport fastest in top end speed. Because of increased stability, speeds higher than the boat's regular top speed are sometimes experienced (as was recorded in the Bass and Walleye Boats test). A very slight drop or no loss in top speed is more likely.



9.  "How does the SE Sport save me money on fuel?"


Quick planing and lower on-plane RPMs will substantially reduce your fuel use. Because the SE Sport cuts planing time dramatically, your time with the "hammer down" will be shorter. Your lower on-plane speeds for tubes and boards will further reduce your fuel use.



10. "Will the SE Sport help with the porpoising action of my boat?"


Whether your porpoising is attributed to poor hull design, a defect such as a hooker or rocker towards the stern of the hull, or improper elevation mount of your motor the SE Sport has been proven to eliminate or reduce a porpoising action.


11.  "Will it help with prop cavitation?"


Yes. Prop cavitation/ventilation where the propeller takes in air on turns is damaging to your motor and lower unit. The crescent-shaped of the SE Sport helps to hold water more firmly around the prop than any other foil on the market.



12. "Of what material is the SE Sport made?"

Polypropylene Polymer, approximately three pounds. Years of experience have shown this high-strength material to be more durable unlike rigid brittle plastic. Tests have shown this to be the material of choice for watercrafts.


13. "Will the SE Sport match the drilled hole pattern from other hydrofoils?"

If your hole pattern is from a previously installed Stingray (trademark of Marine Dynamics, Inc.) or Hydro-tail (trademark of TH Marine Supplies, Inc.) the Sport will match this pattern..You may want to compare your hole pattern to ours on our installation page.


      "What should I use to fill holes for different patterns?"


Marine-Tex White (Recommended) or J-B Weld should be used for filling non-compatible holes. Both products are available through most marine dealers.


14. "Can I reuse the enclosed nylon insert nut if I have to remove the foil from the motor?"

 No. They are designed for locking the first application only.

1. "What size motor or outdrive will it fit?"

Our smaller 200 model is recommended for outboards from 8-40 HP. It will fit all outboards and sterndrives larger than 40 HP except Mercury 40, 50, and 60 four strokes. There are some smaller outboards (down to 4 HP) that it will fit as well. 

2. "What are the dimensions of the SE Sport 200?"

14.3 inches wide, 13.5 inches nose to tail. You may want to refer to our installation page for further details.
