37' Express Cruiser w/twin O/B's

[r.j.dawg]

Seems Sea Ray is coming out with a new 37' express cruiser with twin Merc 300-hp supercharged Verado outboards. http://www.boattest.com/boats/boat_video.aspx?id=2752
Is this the wave of the future???

I saw this also on Boat Test. It's going to be a couple of years i read. There still testing. That will really open up some room. If one does it they all will.Volvo will have to get into the O/B market.

Re: 37' Express Cruiser w/twin O/B's

It's a good idea on the design because you aesthetically cannot tell the difference between the I/O-Inboard versions and the O/B on the Sea Ray. The Intrepid is less impressive because there is no swim platform or thru-transom access, so you are forced to fold down the gunwhale door. My only concern would be the longevity of the SC's Verado's when pushing something that weighs so much. I'm sure the triple-engine boats like that Intrepid have some sort of track-record with them, but when an 18Klbs boat is typically pushed by 400HP twin BBC's or Diesels, I am interested to see how the O/B's hold up.

Re: 37' Express Cruiser w/twin O/B's

Power to weight ratio is better than you might think. Test boat is 15,400 lbs being pushed by 600 HP (25.6 lbs per 1 HP). My 37 is 21,000 lbs being push by twin 7.4L Mercruisers @ 320 HP each, which comes in at 32.8 lbs per 1 HP. That 37, depending on propping, should run >35 MPH.

Re: 37' Express Cruiser w/twin O/B's

Well, my main concern was just the SC'd part of it, not necessarily the power-to-weight ratio. I just looked up whatever the gross weight for the current SeaRay 370 was, so that one is a few thousand pounds lighter. Either way, it's an excellent option if it proves reliable. No more space used/lost than having a traditional engine bay/bilge.

Re: 37' Express Cruiser w/twin O/B's

I would love my boat to be powered by twin outboards. Aside from the ease of maintenance, think of the enormous amount of storage space you would have by removing two big blocks, two transmissions, and all of the associated wiring and hardware. In a 37, you could, literally, turn that bilge area into another berth.

At least with all the room below the deck there will or should be more room to work on the jenny. You know how they squeeze them back in the corner somewhere like they don't ever need serviced

Re: 37' Express Cruiser w/twin O/B's

It looks to me like there is ALOT of weight behind the engines. This has to affect handling no?

Re: 37' Express Cruiser w/twin O/B's

Wow, assuming they have the same amount of tilt/trim range, that sure does open up possibilities for us "Continental Shelf" dwellers. Plus the Carribean would love to see this too. Man, I soooooo need to win the Powerball....

Re: 37' Express Cruiser w/twin O/B's

I would think with the engines that far back, in a moderate wind that boat will act like a wind sock. Bow thrusters would have to be a must for docking.

There not any farther back then any other O/B. Look at this http://www.intrepidboats.com/model-g...ort-yacht.aspx The only Diff. is the o/b's on the SeaRay are hidden from sight. The Intrepid is longer.

Re: 37' Express Cruiser w/twin O/B's

I think a bigger concern for maneuvering is the fact that an inboard boat in that size will have 20"+ props, way out under the boat. This boat has what I assume to be smaller props located far aft. This I think will affect the handling to some degree.

I saw the boat a few months back (online) and although the idea seems plausible, I expected more cabin room.

Re: 37' Express Cruiser w/twin O/B's

@$25K each I don't think 300HP outboards will be replacing inboards any time soon.

This is nothing new. Grady White has been pushing big boats with nothing but outboards for the past 15 years.

Not many 36', #19K diesel or BBC powered boats will cruise at 31 and top out at 50 MPH

If they put one of those new "Seven 557s" on there, NOW we're talkin'......or even better, duals!

Re: 37' Express Cruiser w/twin O/B's

Not that I know anything about express cruisers, but I looked at the boattest link at the start of the thread. It strikes me that calling this a 37' boat is a bit of a marketing exercise. Look at the picks of floor plan etc and it appears there is unused space at the aft end, but in actuality the transom (where engines are mounted) is something like 4' forward from where it would be of a inboard or I/O powered cruiser (??). So it seems that it's actually something like a 33' hull with a swim platform etc cantilevered off the back of the boat making an overall length of 37'. Or am I missing something? This is probably why mustang thought the cabin seemed smaller than expected (?). If you make the hull 3 or 4 feet shorter, that kind of defeats the "space gain" of moving the engines outside.

In my 37', the gennie is in the aft section, under the cockpit sole. The only thing there, with storage on each side. Plenty of room. Engines in the back and move the genset a bit forward,...still plenty of room.

I would think with the engines that far back, in a moderate wind that boat will act like a wind sock. Bow thrusters would have to be a must for docking.

Not at all. Those props aren't any further aft than the props on an inboard boat. Even though the inboards have the engines forward, the transmissions and shafts put the props aft, just under the transom. Engines mounted in the rear and genset moved forward and you've counterec out the weight issue (pretty much). And those O/B's couldn't weigh any more than a pair of BB V-8's and transmissions (including shafts and rudders).
