To Repower or Not to Repower
fairly new to boat owning so I'm putting this question out there to those in the know.
Just bought a 2000 4.8 ribcraft; very canny. It's fitted with what I can only say is a very clean looking 75hp 2001 mercury 2 stroke. On taking it out over the past few weekends, it goes really well: 35mph no less; or as the speedometer reads anyway. Though having considered the amount I'm putting in the fuel tank I seem to be getting around 0.85litres to the mile, when running it around the 30000-35000rpm mark; doing in the order of 20mph. Because I'm liking the boat so much I'm keen to go out more and more, and in turn wondering if I might not get better fuel economy/performance from a newer engine. If then I was to re-power, I say then because plenty have told me to hang on to the current engine, what would others recommend: e-tec 60, 75hp, suzuki 60, 75hp FS, or mercury OPTI 60, 75hp. Are these newer engines any faster or more fuel efficient that what I have already. After all I'm using it for 3 weeks of holiday and as many summer weekends as I can.
Anybody got some advise on what to do??
