We settled on a 19 Tempest as a good all around prop with no jackplate. It was a good stable ride anyone could drive at 57MPH and right at 6000 RPM’s. We ran the 21 Tempest and it was too much pitch. If I remember correct the 19 Enertia ran about the same speed as the 19 tempest, but with a few more RPM’s and felt like a little less lift. On the same boat I ran a 21 and a 22 Bravo LT with a 250 Pro Verado. It was running real good(low 60’s just touching the limiter or real close to it), but it was getting bit light on the pad! The Bravos like running high engine heights as well so even better with your application. If you’re used to running a boat that you actually have to drive I would take a close look at those Bravo’s. Hopefully the dealer has some to play around with. I would start with a 21 or 22 and wouldn’t be surprised if you can spin a 23. If you’re limited to Enertias and Tempests(more common to have in stock) you will be looking at a 21. I’d love to hear what you end up with in the end. Running some setback and getting that engine up this boat should be pretty quick. I always thought with a jackplate, and a bit of time dialing it in, this boat should run in the low to mid 60’s depending on the seating layout( bench models run a bit faster). Those would be pretty impressive numbers for an aluminum boat of this size.
As far as vinyl floors go you can get a vinyl cockpit, but not the entire boat. I will never have carpet in a boat again if I can avoid it.
