But.... unless you can afford to wipe your bottom with $100 bills.... ;) What is the optimum cruising RPM of the HP500? Whatever that RPM is, approx what speed would a triple engine 419 travel? |

So if you could post the speeds at your rpms, would appreciate it.. Have any numbers at higher rpms? 50 divided by 48 = 1.042 Mile Per Gallon 5000 RPM = 70 MPH GPS 44 x 2 = 88 Gallons 70 divided by 88 = .795 Miles Per Gallon By boat is a true deep vee. I would guess that the stepped hull guys who are running faster at the same RPM's would be more efficient? Hope this helps. Dock |
