If in doubt, contact your dealer or the boat manufac-
turer.
WARNING
Using an outboard that exceeds the maximum
horsepower limit of a boat can: 1. cause loss of
boat control 2. place too much weight at the tran-
som, altering the designed flotation characteris-
ticsofthe boat or3.cause theboattobreak apart,
particularly around the transom area. Overpow-
ering a boat can result in serious injury, death, or
boat damage.
Start in Gear Protection
The remote control connected to the outboard must
be equipped with a start-in-gear protection device.
This prevents the engine from starting in gear.
WARNING
Avoid serious injury or death from a sudden un-
expectedaccelerationwhenstartingyourengine.
The design of this outboard requires that the re-
mote control used with it must have a built in
start-in-gear protection device.

2. Place outboard on center line of transom.
3. Tighten transom clamp handles.
4. To prevent loss of outboard overboard, fasten
outboard by drilling two 5/16 in. (7.9 mm) holes
through the transom using transom clamp holes
as a template. Fasten with two bolts, flat washers
and locknuts. Use a marine waterproofing sealer
in holes and around bolts to make the installation
water tight.
