Nick,

I guess I missed something. I know what a prawn is (a large, edible, freshwater crustacean in the order Decapoda). What I don't know is what is a Prawn?

Is this a model of Mercury engine? Is this hood slang?

He is talking about the Verado.

Nick,

You asked a pretty good question in that thread there.
"How can they be available for repowering at this point in time?"
That is a 250 on that SeaCraft isn't it? I wonder if the 275 will be even bigger.

While at work today I did a motor availability search on Merc's dealer site. There are no Verados listed in stock and available.
I would imagine that there is stock but only to dealers who have been through the training. I am guessing that his staff has been through training. Also Merc may be working with select dealers to get some on the water.
If I saw that rig on the water I sure would be heading to my merc dealer for some information.

I saw a pair of 275-HP Verado's on a 320-Outrage while on my boat last Sunday. The powerhead looks to be the same size as the 250-HP.

That picture of the Verado on a SeaCraft in very interesting.

I guess if you have enough influence, you can get one installed as a re-power.

I guess southern Florida is THE market for large horsepower, multiple engine installations. No Verado sightings up north yet.

Not as expensive as they suggested either. He said it "should" be about $700 more than the 250hp Suzuki 4 stroke...installed. Not bad considering it has it's own steering, etc. Problem is his Suzuki dealer might be a rippoff and they really are expensive after all, who knows....who cares, I am not running around with a giant black shrimp on my transom. I will wait till they redesign them in a few years(hopefully).

Nick,
Unfortunately, I haven't seen one yet. An interesting point though, I was talking with a friend who runs a 39' Midnight Special for the Homeland Security with QUAD 225 Opti's. They were looking to repower with 250 hp Verados(the US Gov apparently has the pull needed to get these motors in the aftermarket) but Mercury recommended they stay with the Opti's for the next repower. The reasoning, the Merc guy stated that they have some problems they still need to work out. I don't know what the problems are but they better fix 'em quickly as I've heard the Suzuki is fantastic.

The "problem", as the unattributed informant has described it, may be the steering. Inasmuch as the Verado engine has internal steering, getting four of them hooked up on a transom may take some research and development. The helm is electro-hydraulic, and there may not be a simplistic solution to expanding it to control four engines at once. With the dual 275-HP, a single steering unit is used. If you have four 275-HP motors, the single unit may not be enough to control that beast.

Also, there may be similar concerns with the fly-by-wire controls. The controls have built-in engine synchronization, and expanding this to four motors may take some engineering.

Also, with a four-engine installation, there are a pair of LH and a pair of RH engines. Typically these boats have these installed like this:

RH - LH - LH - RH

(We'll leave it as an exercise for the reader to deduce why this arrangement.)

WIth the electronic controls, it may take some engineering to accommodate this type of arrangement. It may be that there are some problems with the controls and how they are set up with respect to normal/counter rotating engines.

Who knows what the real story is. I doubt that it is a "problem" that most customers are going to experience.

The latest review of the new Yamaha 250-HP 4-stroke says its noise at WOT is a roar compared to the Verado's whisper. The Verado engineering is a whole generation ahead of the rest.

Hi Everyone,

The picture that Jim posted about the Verado on the Seacraft is kind of interesting to look at. If you look at the size of the motor and then look at the small looking bracket that holds its....It sure does not look like it is very strong in comparison to the older Evinrude / Johnson brackets. I wonder what the bracket is made of ???

Here is a link to a guy that has three 275 hp. Verados on a Yellowfin if you scroll down the link thread you will see the photos... Here is a copy of the fuel usage he quoted... Not for me !!! I think I will stick with a single engine for fuel usage.

"numbers we have gotten out of my new 36 with triple 275's

40 mph burning 21.9 gph@ 3500 rpms
50 mph burning 29.8 gph @ 4300 rpms
68.5 mph burning 84 gph @ 5800 rpms

this was 180 gals of gas 4 guys. 10-15 mph winds

ran over 70 with just me in the boat the fuel specs are the same as the 300 hpdi, and 2.5 percent greater at wot than the 250 oti on our boat."

Those are great numbers. I use almost as much fuel going 40 mph on my Mako with one 200 HP Merc (carb).
