Airboat Maintenance

Airboats live in grass, sand and salt. Maintenance here is less about hours and more about what the boat ran through last weekend.

After every run

• Clear vegetation from the engine bay, the cage and the rudders.
• Rinse thoroughly if you have been in salt or brackish water.
• Look at the propeller leading edges in daylight.
• Check for fresh gouges in the hull polymer.

Regularly

Fuel lines, clamps and filters. Belt condition and tension. Gearbox oil level and condition. Cage and mount welds — walk around and look, deliberately, rather than glancing. Steering linkage free play. Battery terminals, which corrode fast in this climate.

Salt water

If you run the coastal marsh, everything accelerates. Rinse the same day, including up inside the engine bay and around the rigging. Aluminium and dissimilar metals in salt is a slow, expensive problem that starts invisibly.

Storage

Fuel left standing over a Florida summer causes trouble. Cover the boat so rain does not pool, keep rodents out of the engine bay, and put it away clean — vegetation left to rot against aluminium does damage.

What to leave to a shop

Propeller balancing and track, gearbox internals, engine work beyond routine service, and any welding on the cage. The cage is a life-safety structure.
