  • high altitude G2 prop?

    I have a 250HO G2, model E250 XH G2, with a Rebel Stainless Steel Prop 15.5x17 on a 2015 2601 Striper. WOT 5700RPM = 42kt., Cruising ~4K RPM 27kts = 3MPG

    This prop works great at sea level where my boat lives, I'm planning on taking the boat to Lake Tahoe and I'm inquiring about the correct size of a G2 altitude prop for my motor.

    Anyone running a 250 G2 at Lake Tahoe?

    I did find a general rule to adjust the sea level prop down 4" in pitch for 6000' of altitude, and 2" for 4000' of altitude, or -1' of pitch for every 1500"

    Because the G2 uses the TBX spline it looks like my only option is the Evinrude SSP TBX 155/8x13", no cheap aluminum options
