Hope this is the right spot to ask…
I am running a 2019 Lund 1775 Adventure, with a 115 Pro XS. I bought it with an aluminum 4 blade 12.5 X 19p. I was running about 43GPS @ 5400rpm, and an amazing hole shot, while fully loaded. I bought a 3 blade 13 X 17p and put it on my boat. The 3-blade brought my RPMs up to 6200, but my hole shot turned to garbage and I didn’t gain anything on the top end. I am thinking about switching to a Stainless 4-blade 12.5 X 19p (same as my original prop, but stainless). Will I gain any top end or RPM over the original 5400 that I was getting on the aluminum 4-blade? I was happy with the performance of the 4-blade, but would like a little more top end.
