27 Power question

[NoBones]

OK gurus,
Here is the quiz for the day..

Would a new single 350HP outboard be enough muscle to push
the recent addition of the 27 CC?

Yes it will not be a speed demon, but that is not the intent
of this boat.

It will be used as a tender for a 70 Hatteras M/Y that will live
it's life in the outer islands of the Bahama's..

Bring it pro and con..

Thanks..

I assure you I have no direct answer. But a 300HP Bravo 3 I/O does well with the 25 seafari- ~27-28kt cruise. So I think you are in the ballpark if the center of mass isn't terrible.

Max allowable HP 600, wweight 7000 lb, rated for dual 2.6 OMC sea drives (2 x 175hp-200hp) or a pair of real outboards.

Expected dry weight?

Hey Ken, I know of one guy who has a 350 Yami, he says it has one problem.....that V-8 eats gas like crazy. However if you can afford a 70'er you can afford gas for this one.

For sure the 557 outboard by 7 Marine, 557 HP electronically controlled aluminum small block V8!

Did I miss something?? When did you buy that?

The 7 Marine 557 is a BEAST! Makes the Yami 350 seem like a boy.

Heck Big Money, why dont you just get 2!

Being that it will be out island, I would go for twins. The new engines are quite reliable, but with little support close by...I'm just saying.

Horse power might be adequate, but torque is likely to be an issue. Planing at low speed is where it will show up.
