I just bought a 2005 Cobalt 220. I've owned Seadoos in the past, but I am new to boating. My 220 has a MerCruiser MX 6.2 MPI engine with a bravo III drive. I'm trying to figure out the optimal cruise speed for this boat. Since conditions vary, I thought it might be better to go by RPM's?? Nobody seems to know the answer, so I thought I would pose a question as to how I would determine this myself?? Thanks. Jack

Someone (Boattest) does know...

We tested three engine combinations for the 220, so be sure and check out the other two so you can determine the one you like best. She is 22’0” long with a trailerable 8’6” beam. The MerCruiser 496 Mag HO with Bravo III outdrive was a sweet ride, and she cruised at 2500 rpm, which turned us out at 27.5 mph. At this speed she burns 7.6gph from her 50-gallon tank, which equates to a fine day of boating up to 163 miles. As I said earlier, she was quiet with only 82 dBa at this speed. Opening her up to top end was tricky on a tightly controlled lake, but we did manage to see 59.8 mph at 4850 rpms. She is ready and able to run with the big dogs on the ski circuit. Her hole shot was only 3 seconds and time to 30 mph was just 7.2 seconds.
