Guard/ABYC regulations.
Instrumentation
CAUTION
If a fused accessory panel is to be used, it is recommended that a separate circuit
(properly fused) be used from the battery to the fuse panel with sufficient wire size
to handle the intended current load.
NOTE: Check the charging capability of the engine. The electrical load of the boat should
not exceed this capacity.
We recommend the use of Mercury Precision or Quicksilver Instrumentation and Wiring
Harnesses. Refer to Mercury Precision Parts Accessories Guide for selection.
If other than Mercury Precision or Quicksilver electrical accessories are to be used, it is good
practice to use waterproof ignition components (ignition switch, lanyard stop switch, etc.).
A typical jet boat of this nature will see water splashed on these components. Therefore,
precautions must be taken to avoid ignition failure due to shorting out of ignition
components.
WARNING
Sudden stopping of engine (shorting ignition components) while boat is underway
will cause loss of steering control due to loss of thrust. This loss of steering control
may cause property damage, personal injury or death.
A warning horn must be incorporated in the wiring harness (see wiring diagram) to alert the
user of an overheat, low oil condition or oil pump failure.
IMPORTANT: If a warning horn system is not installed by the boat manufacturer,
Mercury Marine will not honor any warranty claims for engine damage as a result of
overheating or lack of engine oil.
Route instrumentation wiring harness back to engine, making sure that harness does not
rub or get pinched. If an extension harness is required, be sure to secure connection
properly. Fasten harnesses to boat at least every 460 mm (18 in.), using appropriate
fasteners.
