I like the yanmar but they all are jumping on this electronic bandwagon. The range and smoke improvements are dramatic.
They had a table at the end of the show...The WOT on that boat was 47 with twin 200's and 41 with a single 300 hp diesel. The cruise speed was the same. I bet a few more HP could get you the same WOT and still have an amazing range. Still, 41 is a pretty good clip.
They showed two speeds in detail, the 6 knot troll and the cruise ( I think it was 31knots), in any case at troll it was a blow out. The diesel would run for like 350 hours on a tank of fuel and the ob's were done in like 40 hours. But at cruise, the cummins had 2.5X times the range still. The net cost was about the same. But to me the big kicker is longivity and reliability. They didn't even mention that but you will get 10X the hours on the cummins before replacement. Also, the fuel costs, 1.80 vs 2.59 for gas. The down side is the twin vs single issue (which is significant) but this is offset again by the added costs of twins.
I see more and more boats moving in this direction.
My next boat will have this no question. I can't see me buying into this giant ob trend. (again) (eek I have a 04 225 4stroke...but I was desparate)
With regard to the verado, I think they did some great things in that engine...really, I like the steering, electronic throttle technology (not crazy about supercharging ) but it is an amazing package. What does the 275 weigh? ...is it has to be close to 900# Imagine 3 of those on a 33' hydrosports CC
nice ride but the gas bill has got to hurt.
I have a relative who just bought a 27' CC whaler and it has twin verados (I think 200's) I will be on it this summer for sure. Should be fun.
