MISCHIEF 15 Yamaha F70
Posted: Sun Jul 11, 2021 10:30 pm
The Yamaha F70 on my MISCHIEF 15 accelerates to 4,500-RPM turning an aluminum propeller [of unspecified brand, model, and number of blades] marked as 14.5 x 17-pitch.
[The recommended full throttle engine speed] should be more than 5,000-RPM, and I infer the propeller pitch should be adjusted.
[I plan to replace the current aluminum propeller with a] stainless steel propeller optimized for performance.
Will the weight [of the MISCHIEF 15 affect] the optimal propellor choice?
Suggest a stainless steel propellor pitch that would work best.
