thanks for the response, i also did some research on the web and found a test someone did on 3 new bayliner walkarounds weighing 4400 lbs the 3.0 and the 4cl diesel were at 34.7 mph and the 3.0 outboard was at 44 mph. i figure a v with a 650 lb 3.0 unit it should weigh in at apx 3000 lbs , being optimistic ,38 to 40 mph ?
