More On Outerlimits SV-52 Quad Diesel V-bottom
 

Here's little more detail on the new Outerlimits I mentioned in last week's blog on the company's engine program, http://www.boats.com/boat-content/20...a-closer-look/.

Only one photo with this piece—of the engine installation. Wish more were available. I'm sure they will be.

:drink:YEAAAAA Matt, now we're talking!

That's awesome!

Boy that's a stuffed to the gills engine room for sure! :eek: Thanks Matt for these almost daily updates and articles. You are really working hard to bring us all the inside news. Keep on rovin' bro! :drink:

Fix It Again Tony powered American offshore boat ....oh the horror, the horror....:)

First thing that came to my mind when I read it.

Wow; nice package for sure...triple digits w/diesels.

Curious, why not run two engines in tandem (two drives vs 4) like Bob Morgans 4 engine Skater?

Two engines in tandem never works as well as independant engines, they fight each other ever so slightly. It not like these are 6-71's in a LCM, they had 2 and 4 engines into common shaft configurations.

Also, lesson from Buzzi if you have 4 engines and one breaks you still have 3 props to run the boat with all at full speed, the boat will still run like hell.

curious to see what just 3 of these 560hp mills would do in this exact boat.. probably rigHt AROUND 100MPH.

We made a triple 600hp 46' for the 1990 Venice to Monte Carlo, it ran within 5 mph of the 4 engine Gancia. It would do a 100 mph.

I can tell you the quad boat just handled better.

looks like this could be the next key west to cancun record holder. I would love to go to diesels and asds in my next boat.

Looks like those diesels and Arnesons are a nice package! I agree with the others and would love to see three of those in a 51 open cockpit, Marauder or a Nor-Tech 50.

How is getting these diesels serviced vs the Yanmars and Cummins..

That's a great question. However, since the boat will be based in England, like its owner, I imagine getting Fiat Powertrain service is easier there—if for no other reason than proximity to the source—than it would be here. For whatever that's worth.

And it is essentially a Cummings motor.

Thats what I thought also,when I saw this FPT 560 first time in Italy at Fabio Buzzi,s ,but although it looks identical to a Cummins 5,9/6,7 (the FPT is also 6,7L) the bore and stroke seems to be different ... Fiat/FPT has a jointventure with Cummins ,anybody has some more input on this?

There's no 'G' in Cummins...

The motors arent staggered, how do the front drive shafts end up in the back? any more pics

Drop boxes.

It is based on the Cummins. I work for Outerlimits and have talked with the FPT rep's and mechanics.

Ok,,so FPTuses the block and head from cummins,but different crank and piston specs /size ?

will a Cummins service center than do the repairs if neccessary. Also educate me on these if you dont mind..how are these motors in relationship to size and weight vs the 480/960 Cummins Diesels.. or even the 480/960 Yanmars.. thanks JEFF

NO.... They are based upon the same block as the QSB 5.9ltr was originally made by FPT for Cummins. Cummins recently started making it themselves. The 6.7l is a bored stroked 5.9l..

The FPT 560 is also the same motor as the Iveco but FPT does not at this time have to the same extent a dealer network like Cummins does. The FPT's are a bargain as far as price is concerned over the Yanmars though.

These FPT engines achieved a win for Fabio Buzzi in the UK race the Cowes Torquay Cowes a race of 182 nm non stop in open water and they averaged 91.01 mph to take the flag back in 08 he is entered again this year in the CTC taking place over this weekend the boat is in Class A ... http://cowes2010.co.uk/entrants.htm

Fabio Buzzi's boat the famous restored 46' mono with 4x600hp Fiat diesel engines did it yet again winning the Friday Cowes 100 race and again on Sunday winning the 50th anniversary Cowes-Torquay-Cowes race with it's Fiat engines never missing a beat, the race started at 10am in some pretty rough offshore conditions and gradually deteriorated even further as the race progressed. Diesel engines proved pretty reliable during this race of extreme harsh conditions taking 1st 2nd 5th 8th and 12th although 3rd place was achieved by a US Phantom 38' with petrols great going against the larger Italian boats especially considering the conditions that day.
In some ways this race was a showdown between some of the worlds most legendary offshore Mono hulls and in some of the roughest seas ever raced in to prove themselves ie ... the Buzzi boats 1st and 2nd a petrol 2x 725hp Ilmor CUV 4th and an American hull know for it's sea keeping abilities a 41' Apache with 2x700hp petrol engines 6th, to be fair the Apache although a race boat is mainly as far as I am aware used for pleasure purposes so 1st time the crew have pushed the boat in a race or so I assume

The 52' Outerlimits with it's 4xFiat diesel engines in this thread may have been the only boat able to stop the 2 Italian boats from their dominance this weekend but that we will never unfortunately now know
