Hi everyone... So I am looking at a new outboard powered cruiser (twin 350 Verado's) and the fuel figures aren't too appealing. The review for the boat says it won't stay on plane under 4500 RPM (33 mph) so I am wondering if anyone has any experience on ways to either keep the boat on plane at lower speeds or increase fuel economy some other way.
33 miles per hour is a fast cruise speed so I'm not sure how I feel about that, something around 25-28 mph seems better to me, if I can keep my boat on plane at that speed I'm sure I will see increased fuel economy. The only way I can think to keep it on plane is to bury the trim tabs, but I'm not sure if that will lower the fuel economy with the extra drag. Below is the fuel chart, appreciate any feedback.
