How much weight is being removed with the change of 3 motors verses 2 turbines?

No doubt that should be fast. Fast and tough - a great combination!

03-29-2013 08:58 PMIt will certainly be an interesting combination of old school hull and new school power......
There has not been a lot of Vee hull turbine boats. The Fountain up here didn't do so well with turbines. Neither did the Turbinator Black Thunder.Getting bad advice is unfortunate, taking bad advice is a Serious matter!!

Up here in Portland a guy had a 42' Fountain that he'd put turbines in; sold to someone back east

03-31-2013 09:49 AMWell, looking at these specs, a no drive Merc big block is 1060 lbs. With a 6 it's 1835 lbs. If the turbine is 540 lbs, and the Arneson drive is 285 lbs, that would be a whole lot of weight savings on three vs two. I have to believe there may be a transmission weight also added to the Arneson combination though, and it's included in the Merc weight.
