A 1.85 ratio with 12" pitch prop at 4400 can only calculate to 25mph at 10% assumed slip. The 1.85 ratio sounds off to me, just seems like a 2.0-2.3 range is more appropriate for a 50hp, but that is just me.

I'm currently restoring a bass boat that includes adding hull spine and a full blueprinting of the hull.

A rough guide to choosing the right propeller for your boat, including diameter, pitch, hole shot, prop slip, number of blades etc

Since it's nearly impossible to have a 100% efficient propeller, the amount of "slip" is usually expressed as a percentage. For example, if that 24" pitch propeller only moves a boat forward 20 inches with each revolution it is 83.3% efficient, or has a 'slip' factor of 16.7%.

Calculate the propeller slip: Subtract the ship speed from the propeller pitch, divide it by the propeller pitch, and then multiply by 100 to obtain the slip percentage. For example, let's say the propeller pitch is 30 inches, and the ship speed is measured at 20 knots (1 knot = 1.15 mph).SpitFire X7, a new stainless steel propeller designed to increase speed and acceleration on all boat types with mid-range outboards.

Proper setback and balance also helps. If you have to trim way out the prop is not applying it force all in a forward direction. At the very least you lose the vector, plus driving the stern down. forrestercb.Divide by 5280 = Miles per minute, multiply x 60 = miles per hour. This can be shortened to (Pitch x RPM) / (Reduction x 1056) = MPH. Slip is figured by comparing this theoretical speed to the actual measured speed.

Share ...In reality since the propeller is attached to a shaft it will not actually move forward, but instead propel the ship forward. The distance the ship is propelled forward in one propeller rotation is actually less than the pitch. The difference between the nominal pitch and the actual distance traveled by the vessel in one rotation is called slip.Betting Calculator.
