WARNING
Recharging a weak battery in the boat, or using jumper cables
and a booster battery to start the engine, can cause serious
injury or product damage from fire or explosion. Remove the
battery from the boat and recharge in a ventilated area away
from sparks or flames.
Bottom of Boat
To maintain maximum speed, ensure that the boat bottom is:
• Clean, free of barnacles and marine growth.
• Free of distortion, nearly flat where it contacts water.
• Straight and smooth, fore and aft.
Marine vegetation may accumulate when the boat is docked.
This growth must be removed before operation; it may clog water
inlets and cause the engine to overheat.
Inspection and Maintenance
Inspect the power package often and at regular intervals to help
maintain its top operating performance, and correct potential
problems before they occur. The entire power package should
be checked carefully, including all accessible engine parts.
1. Check for loose, damaged or missing parts, hoses and
clamps; tighten or replace as required.
2. Check plug leads and electrical leads for damage.
3. Remove and inspect the propeller. If nicked, bent or
cracked, see your authorized Mercury Marine dealer.
4. Repair nicks and corrosion damage on the power package's
exterior finish.
Attention Required After Submersion
• Before recovery, contact an authorized Mercury Marine
dealer.
• After recovery, immediate service by an authorized Mercury
Marine dealer is required to prevent serious damage to
power package.
