Because of the mechanical throttle linkage,
the remote control levers may not be exactly

TIP:
This boat is equipped with a “start-in-gear”
protection. The engines will not start unless
the levers are in the neutral position.

This boat uses a direct-drive propulsion sys-
tem. Therefore, jet thrust is always being pro-
duced while the engines are running. The
