Have a 40' Motoryacht with two 446 Cummins MerCruiser 480 CE diesels. Have received conflicting info re GPH and knots per hr. Can anyone tell me what it might be @ 1000, 1500 and 2000 rpms respectively? Coming up from Mexico and would like to make it without rowing! Thanks

Sydney:
Those are the 480CE motors. They (should) have smartcraft. Smartcraft has a quite reliable GPH reading in one of the screens. Ignore the MPG reading as it is not very accurate. Provided you have GPS, you should be able to do the math at varying RPMs and then make a nice chart of MPG and find your sweet spot.
BTW...I think you are the first 390/40MY owner on CSR.....
