Yamaha F90 Service Assumptions and Notes

  • The Yamaha F90D manual calls for a minor inspection service at 50 hours / 3 months, then service at 100 hour / 6 month intervals thereafter.

  • The service at 100 hours / 6 months is different than the 200 hour / 1 year service. Based on recommendations from local Yamaha dealers, the 6 month and 1 year services have been combined into a single annual service. The following significant items would typically be included in this annual service:

    • General inspection: engine anodes, fuel system, power trim and tilt, PCV, thermostat, timing belt
    • Minor adjustments: idle speed, shift and throttle linkage
    • Fuel filter replacement
    • Gear lube change
    • Engine oil change with oil filter replacement
    • Friction point greasing
    • Cooling passage cleaning
    • Water pump replacement
    • Spark plug replacement
  • We are estimating the cost of parts for this services as follows:
    • Fuel filter: $4.99
    • Gear lube: 32 oz. Yamalube Gear Oil = $7.45
    • Engine oil change with oil filter replacement: 1 gallon + 1 quart Yamalube oil ($20.95), plus Yamaha oil filter ($12.95) = $33.90
    • Water pump replacement: water pump service kit = $29.79
    • Spark plug replacement: 3 x NGK spark plugs = $6.27
