I own a formosa center cab (walk around) 550.the boat has a 4mm plate hull with a 15deg dead rise, overall length is 5.65m, beam 2.40m, weight 620kg, floor to gunwale 700mmx3mm, has a 150ltr under floor tank and is registerd to carry 6 people + gear + motor to the weight of 775kg = combined weight of1395kg + fuel.I carry a 80ltr esky with ice for fish.It is powered by a m140hp tohatsu 2stroke which is mounted on a pod. this boat and motor is only 12months old bought brand new. Has only 30hrs on the clock. It is using up to 40%+ more fuel than a blue band 2stroke mercury. my prop is 13.25"x17"p same as the 100hp merc. on a 19ft fiberglass half cab carrying more weight. should i go bigger in the prop or could it possible be tuning. the motor will rev to 5800+ at WOT. coming up out of the hole it struggles when fully loaded and has trouble holding up on plane when you just want to cruise. seems like you have to travel flat out all the time. I am tending to think I should go less piitch or smaller prop, so as to help at lower revs.
