Additionally, check if the motor can handle the load and any potential increase in operational efficiency. Always consult with a professional or refer to the manufacturer's guidelines to ensure compatibility and optimal performance.
This is how to fix the impeller on a Chrysler 25 HP outboard motor. Disconnect the coupling that's on the outside of the leg, flip the housing and twist in impeller.

What year? It may require special tools.
change impeller or check for blocks in water lines
A lot! This all depends on the type and size of the supercharger. At boost levels of 7psi you can expect around a 40-45% increase in HP. At 15psi you can expect around 100% increase in HP. HP really depends on boost levels and existing engine HP.
