Yamaha AR240 HO, SX240 HO, 242 Limited S, 242 Limited 2016 Owner's Manual

The Yamaha AR240 HO should undergo regular maintenance as outlined in the owner's manual. This includes changing the engine oil every 50 hours or annually, checking and replacing the air filter, inspecting the spark plugs, and ensuring all safety equipment is functioning properly.
If the engine won't start, first check the battery connections and ensure they are tight and corrosion-free. Verify that the fuel tank is not empty and that the fuel valve is open. Inspect the spark plugs for wear or damage and replace if necessary.
If your 242 Limited S is overheating, stop the engine immediately. Check for any obstructions in the cooling water intake. Ensure the cooling system is not clogged and inspect the impeller for damage. Refill the coolant if necessary and consult a professional if the issue persists.
To winterize your Yamaha 242 Limited 2016, flush the cooling system with fresh water, drain the fuel system or add a fuel stabilizer, change the engine oil and filter, and remove the battery for storage. Cover the boat to protect it from the elements.
Regularly inspect the jet drive for debris and clean it using fresh water. Check for any signs of wear or damage to the impeller and clean the intake grate. Lubricate moving parts as recommended in the service manual.
To improve fuel efficiency, ensure your boat is not overloaded and distribute weight evenly. Regularly clean the hull to reduce drag, maintain the engine as per the manufacturer's guidelines, and adjust your cruising speed to find the most efficient range.
First, check the fuse for the stereo system and replace it if necessary. Ensure the connections are secure and the battery is charged. If the problem persists, consult the stereo system manual or a professional technician.
Inspect the steering cables for any signs of wear or damage. Check the steering wheel for proper alignment and ensure there is no obstruction in the steering mechanism. Lubricate the steering components as recommended in the service manual.
First, disconnect the battery to ensure safety. Remove the engine cover and locate the spark plugs. Use a spark plug socket to remove the old plugs, then install the new ones by hand to prevent cross-threading. Torque them to the specifications in the owner's manual.
To protect the hull, regularly apply a marine-grade wax to the surface. Use fenders when docking to avoid scratches and inspect the hull for any signs of damage frequently. Clean the hull regularly to prevent algae and barnacle build-up.
