I have a 2012 260 Sundeck with the base engine. Over the 60 hours of operation I've had it, looks to me that I get my best fuel economy at around 3300 RPM which in relatively calm seas, moderate wind, gives me a speed of 21MPH (GPS readout) and the dash readout shows a fuel burn of 7 GPH which works out to 3 MPG. What I haven't yet done, but will soon is experiment with, is the trim. I cruise at that speed with the trim full down. (not referring to the hydraulic trim tabs) but the i/o unit trim.
My question is if I trim up a bit, that should lift the bow out of the water which ought to mean less friction and higher speed with the same fuel burn, right? Any suggestions on how I might find the optimal speed? Or will I find that I've pretty much found the sweet spot and any trim adjustment isn't going to be very noticeable.
Thanks in advance for any shortcut to determining this you can provide.
