The old 454 Magnum is getting tired so I decided to go down a pitch.
SNIP
With a full tank and max capacity and gear, I am very surprise how the Mercalloy prop handles the load, actually better hole shot than an SS. |
If you go down in pitch, the hole shot should be better.
4 blade aluminum props are a nice compromise, IMO. That said, a few years ago, I had a boat with a 4 blade aluminum and upgraded to the same diameter and pitch 4 blade SS prop (with more rake though). My boat gained a couple of MPH on top with the same WOT RPM, and mid-range acceleration was noticeably better. Hole shot felt the same. Mid-range punch is what actually sold that boat. The first guy to test drive it was cruising at 3000ish RPM and I said "punch it", the resulting acceleration from 30ish to 50+ produced a huge smile and I knew right then and there that I would be getting my asking price. Helped that it was a really nice boat and a reasonable price, I'm sure.
