2003 38/40 Open performance #s

Nice fish! But more interested in the deck? What product is that? How long have you had it?

Are these posted numbers per side or total? By the way beautiful boat just purchased same package.

In thought so and just making sure. Very similar to what I experienced with mine. Will post a pic shortly

Since I am stuck in the house with a new child I have plenty of time to post numbers.
38/40 convertible 450c Cummins numbers are with a fresh bottom, full fuel and water 6ppl all gear and 300 lbs ice ( standard day trip). This boat is under propped due to our heavy overnight load out which usually includes the above plus 150 gal of extra fuel on deck and 300 more lbs of ice. Dirty bottoms or not she never gets over 175 degrees this way. After 550 hours the aftercoolers show no signs of overloading ( see seaboard marine for info on that). I have found the boat picks .5kts per 1000 of weight taken off.

1100 rpm 7-8kts 5gph
2000 rpm 14-15kts 20gph
2200 rpm 17-18kts 27gph
2300 rpm 19-20 kts 32gph ( usual cruise)
2400 rpm 21-22 kts 36gph
2650 rpm 26-27 kts ? Only do this once a trip for a min or two to check engines. .

Boat is 1kt quicker across the board with half fuel and 3ppl. 2” of pitch to the props would pick it up more but as earlier stated we load it too much tooofter to worry about it.

Thanks JW for that VERY comprehensive breakdown!

Working on a deal right now to pick up a 40 open...fingers crossed we can work out a deal and start changing things up to suit the family’s needs!
