Quick Prop Question

wrote: Hey! I have a 17' Bowrider (fibreglass) and it has a 140HP I/O Engine. It's a 1977. I have a 14x19 prop on there right now... I had it up to about 40MPH and it seems decent at initial acceleration. I'm looking at purchasing a second prop for it as a spare but would like to get one to compliment the existing one... I'm looking for suggestions on what to purchase... Does it have to be a 14" diamater? Are there various hub sizes on the props for Mercruisers? Any advice would be great! Thanks, Sorry, but there aren't usually "quick prop answers". ) You *can* use different props for different purposes (I have one prop for water skiing/tubing, and another for "high speed"). What is important is to NOT use a prop that allows the engine to exceed the Wide Open Throttle (WOT) recommendations of the manufacturer, OR drops the rpms so low that you lug the engine. Follow the WOT range stated for your engine. Go to your local dealer, or go online to a reputable prop dealer, and find the recommended prop for the specific use you have in mind. Specific to your question: No, it doesn't have to be 14". Match the prop to the specific outdrive you have: Alpha, Beta, etc. The pitch of the prop will affect performance more than the diameter.
