Ok here's a sneak of the Yanmar part of this thread.
A little shop floor tuning before the final install.

nice...kinda getting to the point where these engines don't even look like engines anymore though.

I know Yanmar has a great reputation but 380hp from only 270 cubic inches sounds like it is not gonna have the usual diesel lifetime.

I am going to check this thisng out in about 3 weeks. See you then Terry

I think this is just a transom extension of the 50. Why would Nor-Tech build a new boat of only 52' LOA?? Why not 55' or even 60?

Not to beat a horse, but it boils down to what is "usual diesel life"?

In our gensets if don't get at least 10,000 hours between overhauls it's a junker. You use a pleasure boat 200 hrs a year is a lot so is 5 years good, than 1,000 hrs is acceptable between overhauls would be acceptable.

i agree their stretching it out a little...only so many ponies you can get and stay reliable. kinda reminds me of the duramax thread. habanajoe...whats your take on v-8 versus an in line 6????(if this hasn't been discussed before)

Gotta be these!

That has been beat to death here a couple times but my take is simple in-line has more main bearings per cylinder than a V-8. The rod bearings can usually be larger on an in-line as well because on a V you have to offset something to increase the width of the bearing either the rod in the piston or the rod on the journal, both are not as good as centered as in an in-line.

For applications like we're talking about here a CC for pleasure applications that will not be a high hours application the V gives more room, 2 extra cylinders for a shorter space, that adds Hp. Like I said and asked before what is acceptable diesel life - do you measure it in years or hours? I think performance diesels engines need to last for 10 years to be truely great engines, at 200 hrs a year which is allot for most that is 2,000 hrs.

I can't believe it but a sneak peak if the new 52 Roadster is on Facebook.
