"Is there a place where I can look up the specs and ratings on older Mercruisers? I am in the market for a used boat and I'd like to be able to look up information on each motor. For example, the latest boat I found has a Mercruiser 260/V8. I believe its a 350 ci with a HP rating of 260 (so I guess some motors show displacement and others show HP rating?). It has an aluminum 19 pitch prop and drives a 21' Eliminator no more than 50 MPH. Seems slow. Is it the motor or the prop? Its mounted to an Alpha One. The seller claims I can get more speed with a different prop. ??? Thanks for any help!!"
