Prop pitch vs. elevation

[lakepowellnut]

So I bought a motor out of a lower elevation area and have been having issues getting it on plane, I thought I would need to re-jet the carbs, but is it just a matter or changing the prop that I should be looking at?  I'll have to look into this, it sounds a lot easier to accomplish... How do you size the props?  I'm sure it has a lot to do with boat weight, motor size and etc... but do you have a good resource to check so you don't have to do an expensive game  of parts changing?  Thanks J

This can help you finds the right prop for your boat.  The more information you can fill in the better.

I use Mercury’s prop selector app to get a baseline, but that’s about it. The downside is it doesn’t know which boat hull you have. For example, on my Ranger that I’m trading in, the prop that Mercury recommends is a Tempest Plus. It runs good, doesn’t slip, and can I can get about 53MPH fully loaded. My Fury prop is a different story. Not only does it do all that the Tempest Plus does, I gain about 5MPH and that’s why it’s prop I would always run with. The Tempest Plus was my backup. All in all, find a prop dealer that has a loaner program and play with props. Once you have decided on one, buy two. It sucks ruining a prop and can’t get back to the dock.
