CAUTION! – Lowering the propeller into the water or shifting into forward at a high engine
rpm may cause a standing operator or passenger to lose balance or be ejected from the
boat. ALWAYS ALLOW THE ENGINE TO COME TO IDLE OR SHIFT INTO NEUTRAL
BEFORE LOWERING THE PROPELLER INTO THE WATER!
NOTE: AFTER YOUR FIRST TEST RUN ON THE WATER IT IS NECESSARY TO
REMOVE THE DRAIN PLUG (SHOWN ON PAGE 10) AT THE REAR OF THE DRIVE
HOUSING TO CHECK FOR WATER LEAKING IN. THIS BOX MUST RUN
COMPLETELY DRY. IF WATER COMES OUT OF THE DRAIN PLUG THE COVER
PLATES MUST BE REMOVED AND RE-SEALED WITH A GOOD GRADE SILICONE.
PERFORM THIS CHECK ANY TIME THE COVERS ARE REMOVED AND REPLACED.
Low Speed Operation
As described before, let the engine warm up for a few minutes. Holding the handle
carefully, remove the handle rope and get a feel for the balance of the engine.
For the first time operating your new Surface Drive engine, turn the trim adjustment knob
counterclockwise until the prop and cavitation plate can be fully submerged while the boat
is floating at rest. Under normal conditions the trim can be adjusted for high speed
performance and does not need to be changed while idling or getting back up on plane.
Steer the engine slowly to avoid getting water into or overturning the boat. The
Go-Devil Surface Drive engine is better suited for wider bottomed boats (48” or wider).
Use extreme caution- even while idling -when making sharp turns on narrow boats.
To turn the boat around in a tight situation, allow the boat to nearly come to a complete
stop. While the engine is idling and in neutral, turn the engine all the way to one side and
shift into forward. Most boats will turn in their own length when this is done.
TIP! - Turning left at low speed requires less reach due to the handle being on the left
side of the engine. When reversing direction from rest or idle speed, set up to turn left
whenever possible. This will become instinctive with time.
High Speed Operation
As its name implies, the Go-Devil “Surface Drive”, uses a surface piercing propeller. The
surface propeller is designed to be run primarily with a fraction of each blade breaking the
surface of the water with each revolution. To get maximum performance from the engine,
propeller depth can be fine tuned using the manual trim.
The manual trim mechanism is a standard feature on all SD models. The trim is simply
a bottom stop on the tilt axis of the engine which allows the engine to tilt upward freely
when an underwater obstacle is struck.
