Don't discount the set up from the manufacturer - some are having outstanding results with the NXT. Might be worth looking a little deeper.

Working great for Cigarette. I know the X deminsion has something to do with it. There may be other differences as well.

Works great on the Donzi 38ZR Handles great and runs even better.

the 32 DCB at the power boat trials was running 17X40 merc CNC 5 blades, too much diameter= transon lift,they normaly run 16.5X38's with no issues the 40's were just for big numbers,,,140mph on the limiters :D

Working great on the Sunsation F4 too, boat runs on rails. They found out on set up that X dimension had a lot to do with it.

How would you know.You don't keep a boat long enough to even sea trial it before you sell it.Must be related to ThunderDan.:evilb: :evilb: :D

LMAO - can we ask Jeff how well the arnesons do?:evilb:

Oh yeah Jeff - when you called last Friday while working, this was us stopping for lunch. You are welcome to join us anytime.

Fountain reps told me 90, and my velocity prediction program gives the same answer.

I am very intrigued by this combination. Its a bit faster than triple 525s, and obviously a LOT simpler, lots more room in that engine room, and its a whole engine lighter (that's why its faster with a bit less power).

The twin diesel sounds really practical too -- get 2 mpg at cruise, and diesels cruise close to flat out. About 1.6 mpg flat out. About 70 mph, I think they said. And the rebuild time is forever. Of course, other stuff goes to hell, but not the drives or engine. The intercoolers clog, turbos fail, wiring goes wonky (just like on all EFI gas engines), etc. So maintenance is still needed. But its amazing when you look at a 2000 hour yanmar -- it looks and usually runs like brand new.

Here we go again - Jassby is going to build another Yanmar boat!:drink:

So are you saying the boat would be faster with Merc?
