Water-Cooled Engine
Because the Dynamite ® .15 engine is water-cooled
and not air-cooled, make sure that you do not run
the engine for an extended amount of time outside
of the water. Continuously monitor the water
outlet when the boat is running to make sure that
water is flowing through the engine head. If the
water does not reach the head to cool it, the engine
will overheat and fail. This will cause permanent
damage to the engine.

open for the high-speed and 2 1 ⁄

turns open for the
low-speed needle. This should give you a slightly
“rich” mixture of fuel to the engine. This setting is
the safest way to break in your engine. For further
details regarding the carburetor, see the Dynamite
.15 instruction manual.
