I have twin Honda BF250 IST motors on my 27 Tournament. First pair I was turning 6350 rpm’s with Solas Lexor 17 pitch props at 51mph. This pair I decided to mount engines one hole lower and I am turning 6100 rpm’s with Powertech 4 blade 18 pitch props at 51mph (I gained one mph after about 40 hours). Totally different ride with the four blades as I now have a mid range.
