The proper prop size will vary. It will depend on boat size and weight, engine horsepower and lower unit gear ratio.
When you select the prop you need to make sure that your engine runs in the power band without over rev ving

Think of the props pitch as being like gears, the higher the number the faster potential top speed, the lower the # the faster you accelerate but at the cost of top end. 4 blade props give better acceleration but 3 blade have a higher top end potential.

yes, and more important is the pitch of the prop. Ask a dealer for the best fit for your intended use... I have three props for my 19' Stingray I/O (240 GM)

the prop is a gear, in a nutshell, you need to know the wieght of the boat, the style, and the size of the engine

Ditto with the Turboprops. The Russians got here upon this out interior the Fifties. collectively as the U. S. grow to be busy with heavy bombers such because of fact the B-fifty two and B-40 seven, the Russians desperate to apply rapid-prop plane with contra-rotating propellers. The plane grow to be referred to as Tu-ninety 5. This plane grow to be slower than the B-fifty two, yet grow to be waiting to succeed in the U. S. mainland. So the rapid prop is alot greater gas effecient. this is a few stats
