That's odd (illegal?) for a boat manufactured in 2007.

Are you suggesting the absence of a CE plate means you can fit any hp motor that you choose?

I know of a SR4.7 (rated to 70hp max), which was fitted with a 90hp. Doesn't make it right, though.

Have you been onboard a 6.2 with a 150hp longshaft motor, to give you something on relatively even terms to compare it with?

Andy mines got a CE plate too!

As I went for the maximum rated hp I had the transom knee fitted as the cost is minimal

Stephen if you do go for a Vipermax, spec it with two under floor cable ducts one to each transom box

What's the reason for that? I guess one side takes the engine wiring and plumbing, what would you use the other side for if fitted?

Transom knees sound like a good idea with nigh on quarter of a ton of motor on the back.

Anything else I should think about at build time??

Power steering pipes, nav light power, bilge pump power, transducer cable, It's not an expensive option at the time of build

+ I'd go for a 220 L fuel tank again a low cost option

Two under deck trunks - very worthwhile. Transom knee already mentioned. Bolt down removeable jockeys if going for a second row of seating. I've also got a couple of bolt down points in the forward desk for tying down anything that I might wish. If your boat will take it I like the look of the new Osprey Searider console
Oh, and I heard somewhere that Osprey are now making narrower jocket seat bases, which I would go for as the ones that I have got are too wide at the base to my mind.
