  1. Ordered with the high altitude option, your new boat should be just fine with the 320 motor. I have a 05 204ssi with a 270hp GXI drive. I have had trouble turning more than 4600 rpm at high altitude, no matter what prop I have tried. There is a Volvo service bulletin that gives recommendations for gear ratio for high altitude. My boat also was from california and did not have the correct gear ratio. That may have been the problem with your old boat. http://www.marinemec...ituderatios.pdf

I need to change the gear ratio in my outdrive. http://www.marinemechanic.com/volvo/volvo/2010/44-0-8_A%5B1%5Dhighaltituderatios.pdf
