leftcoastangler Posted April 10, 2019 Report Share Posted April 10, 2019 Looking to purchase a Mercury Spitfire X7 in 13x17p SS. I have a 12.7x19p Spitfire x7 (perfect condition) and I can't get the rpm I need. If anyone knows someone who might be looking to sell a Spitfire 17 or trade one or similar for my current 19p Spitfire, please let me know.

THE OUTLAW Posted April 11, 2019 Report Share Posted April 11, 2019 I ran both of those on my boat . The 13x17 is the ticket , ported 1/4” . Right on the revlimiter . Could only spin 6100@50 on the 12.7x19. 🇺🇸☠️ Quote Link to comment Share on other sites More sharing options...

I'm hoping the 17p can get me at or closer to 6000 rpm and maybe pick up some speed in the process. Quote Link to comment Share on other sites More sharing options...
