12/Seasonal Maintenance
12.1 Engine
Refer to your engine manual for any specific information pertaining to your engine. For the fuel
system, add a fuel stabilizer to a full fuel tank as per the stabilizer’s instructions. Run the engine
for a minimum of 10 minutes to allow the fuel stabilizer to reach the engine.

Remove the engine cowl and spray the engine’s powerhead with a non-conductive lubricant
spray. Do not spray directly on joints that are lubricated with grease as some lubricant sprays may
dissolve grease.

Grease all external zert fittings on the engine and steering system. Use grease that is consistent
with engine manufacturer’s recommendations.

Change the engine lower unit lubricant. This will remove contaminants that may have built up
throughout the boating season. This is also a good time to check for lower unit seal problems. If
there is a leak, have it repaired by your dealer.

Remove the propeller and grease the propeller shaft. Inspect the shaft and propeller for unusual
wear or signs of deterioration.
12.2 Hull
Wax the entire boat. The hull will maintain its factory delivered luster much longer if waxed at
least once a season. The inside of the boat, which is subject to the sun’s direct rays, will also
respond well to a good coat of marine wax.
DO NOT wax the non-skid surfaces.

Remove the hull plug so the sump area can breathe.
12.3 Storage
It is best to store the boat inside, however if inside storage is not available, use the following
guidelines in order of preference
Under awning with no boat cover
Outside under cover: Boat cover should allow ample ventilation and be removed periodically to
allow moisture to dissipate avoiding mildew growth and staining.
12.4 Trailer
Check the wheel bearings for water. Clean and re-pack or replace as necessary.
Check the tires for proper inflation.
Try to store the boat and trailer with the bow slightly elevated so it will drain.
If possible, cover the boat so that the sun will not deteriorate and tree sap and other
environmental hazards will not damage the deck or upholstery. If covered, make sure to let air
circulate so mildew will not build up. If in a high snow or rain area, make sure to properly support
the cover to sustain and shed the load.
