Frequently Asked Questions - FL115 (2022) YAMAHA
What type of oil should I use for the Yamaha FL115 outboard?
Use Yamaha 4-stroke outboard oil or an equivalent API SG, SH, SJ, or SL grade oil with SAE 10W-30 or 10W-40 viscosity. Change oil every 100 hours or annually.
How do I flush the engine after use in saltwater?
Attach a garden hose to the flush port, turn on the water, run the engine at idle for 5-10 minutes, then shut off. This removes salt deposits from the cooling system.
What is the recommended fuel octane for the FL115?
Use unleaded gasoline with a minimum octane rating of 87 (R+M/2). Avoid ethanol blends above E10.
How often should I replace the spark plugs?
Inspect spark plugs every 100 hours; replace every 200 hours or if fouled. Use NGK LFR6A or equivalent.
What is the break-in procedure for a new Yamaha FL115?
For the first 10 hours: vary RPM, avoid full throttle for more than 5 minutes, and do not run at idle for extended periods. After 10 hours, change oil and filter.
Why is my outboard overheating?
Check the water intake for debris, ensure the impeller is not damaged, and verify the thermostat is functioning. Also check the tell-tale for water flow.
Can I use the FL115 in shallow water?
Yes, but avoid running the engine in weeds or mud. Use the power trim to tilt the engine up in shallow areas. Always monitor water depth.
What is the gear ratio on the FL115?
The gear ratio is 2.00:1. This provides good torque for acceleration and planing.
How do I winterize my Yamaha FL115?
Stabilize fuel, fog the engine with oil, change gear oil, drain water passages, and store vertically in a dry location. Consult the manual for exact steps.
What propeller size should I use for my boat?
Selection depends on boat weight and intended use. Typical ranges: 13.25x17 to 15x21. Consult a Yamaha dealer for optimal pitch and diameter.
