Drill-Free
TM
Installation:
The SE Sport 400
TM
comes with all the hardware you need. (Four Disk-Grips
TM
,
rubber washers, bolts, washers, adhesive strips, and lock nuts.) *Most installations
will only require a 7/16” open end or socket wrench, and a Phillips driver.
Remove the top Trim Cover
by gently sliding the cover forward to release.
Clean the cavitation plate
of all oily residue,
top and bottom!
You may need
to use rubbing alcohol to thoroughly clean the surface.
Place adhesive strips
on the top surface
of the cavitation plate near the outer edge, and close to
estimated assembled disk location.
(Remove adhesive strip liners.)
Drill-Free
TM
Disk assembly:
Set the SE Sport 400
TM
on the cavitation plate and
select the hole pattern
closest
to the size of your cavitation plate. Place the
D-shaped washers in the foil top channels over the selected holes, and insert
carriage bolts in these four positions. (Long bolts rear and short forward.)
(Hole patterns for 5, 6, 6.5 and 7 inch wide plates with a 1/4” additional
tolerance are marked on the foil.)
Place the 2” rubber washer
on the Disk-Grips
TM
,
under
the cavitation plate,
and place the 1” steel washers on the Disk-Grip
TM
bottom, followed with the
5/8” washer and lock nut. Make sure the step in the Disk-Grip
TM
aligns with the
outside edge of your cavitation plate. (The rubber washers will conform to the
step when tightened.)
Tighten the lock nuts
with a small socket wrench
slowly
to prevent thread
galling. Use an alternating torque pattern until the rubber washer on the Disk-
Grips
TM
is substantially compressed. You will feel the nut get harder to turn, and
add another half to full turn and the grip will be accomplished.
You can break
the bolt with continued tightening.
(Once tightened, avoid loosening the
lock nuts.
Do not use a power socket.
)
I
nstall the Trim Cover:
Place the Trim Cover on top, 1/2 inch forward of the
foil, and slide rearward while pressing firmly down on the center to engage
the mid interlocks. Once lined up with the center screw hole, use a Phillips
driver to hand tighten the screw until snug.
(Do not over-tighten the screw.)
Final check for tightness:
Tug the Sport 400
TM
firmly from side to side. It
should feel very solid with no movement. In all cases, the bolts must fully
engage the nylon insert area of the lock nut to be secure.
Safety check:
We recommend a check of the hydrofoil tightness before and
after your first day on the water. The engineered composite Disk-Grips
TM
are
designed to withstand aggressive tightening. The lock nuts can usually be
re-tensioned an additional quarter to half turn or more at this time, without
removing the Trim Cover.
Maintenance:
Check regularly for weathering of the rubber washers and
Disk-Grip
TM
tightness. Re-tension only if needed. See your dealer or email Sport
Marine for replacement parts if needed.
(
Note
) Installation adjustments: Cavitation plates of 8“
width require SE
Sport 400
TM
modification for Drill-Free
TM
installation. Contact Sport Marine
Tech or www.sesport.com for written instructions and photos.
*The Mercury 40
HP
, 50
HP
, and 60
HP
FourStrokes
have a 6.5” plate width at
the rear disk mount position. Pilot holes are provided to guide drilling the Sport
400
TM
with a 1/4” drill bit to fit these motors. Use the standard 6” hole position
for the forward Disk-Grip
TM
mounts.
*The Honda 200
HP
and Yamaha 350
HP
have larger 7.25” wide plates. To mount to these cavitation plates, you may
need to slightly expand the outside holdes outward with a small round rasp or
1/4” drill.
*Various Evinrude 200
HP
- 300
HP
range models may require drilling
the 6.5” pilot hole, and expanding the forward outside holes for the best fit.
Measure for the closest hole pattern before installation.
The SE Sport 400
TM
is not recommended for Volvos
with exhaust through
the cavitation plate. The SE Sport 300
TM
is recommended.
Conventional Drill Assembly:
If you prefer to drill your cavitation plate, set
the Sport 400
TM
in the desired position and mark the four inside holes with a
center punch. Drill the four inside hole placements using a 1/4” drill bit. Install
using the same hardware without the Disk-Grips
TM
and rubber washers. (Or,
optionally, choose to drill two holes and use two Disk-Grips
TM
.)
