    lund 1775 pro guide prop?

    I have a 2018 1775 pro guide with 90merc . I'm running a spitfire x7 13pitch. I'm turning 6k rpm getting right at 35mph. I run 3 trolling batteries ,medium gear load. the hole shot great and gets on plane super fast. just wondering what kind of numbers I would get with a 15pitch. we tried a 17pitch and wasn't getting the rpm"s.

    Try an X-7 Stainless Spitfire.. It will help a little because you can trim higher . It stays hooked up well. I'm amazed you are only getting 6000 out a 13 p. Are you sure it is a 13 pitch.? (I ask because the prop diameter of a spitfire aluminum for a 90hp is 13.) A 13p @6000 doesn't compute to your 35mph speed. At any rate, Lund recommends 15 or 17p X-7 Spitfire for the Stainless upgrade on a 1775 Pro-Guide w/ 90 Merc. (depending on load)
