A change in the prop pitch will increase or decrease the engine RPM's and can be used to bring them into the recommended range. A 2" pitch increase (for example, from 21" to 23") will result in approximately a 300-400 RPM decrease and vice versa. here
Re: How to get more out of a 15hp 2 stroke yamaha?
If a boat requires an 18 HP MINIMUM then the boat is already underpowered. Acceptable boat performance generally is with an engine that is 70 - 75% of the boats maximum rated HP. If that boat calls for 40 HP maximum, then a 28 - 30 HP would provide acceptable performance and with anything less performance becomes marginal, especially if heavily loaded. If you are on the water all day you want more power, not less. What boat size and type are you considering and what is it's MAXIMUM rated HP?
Like I said a big difference when you try to load and unload this to the back of a sedan between 36-41kg with one person. here
