So today I finished the first 3 hours operating below 4k RPM. I had 3/4 tank of fuel and when I'm using the boat in the summer I usually carry about 100 lbs of ice. Today no ice for the test. I'm turning a 14X18 Suzuki prop and when I went open it up to WOT I easily exceeded 6000 RPMs. I very briefly saw 6500 and feel there was more throttle to go. I'm thinking a 14X20 prop may be the ticket. Does that sound about right? It's a 2015 Suzuki 140. Thanks
