I want thank all of you for responding to my post!

1st. The 27 CC is not mine, it belongs to a friend of little Kenny!
He is working on it here at Area 442, why? because it's here.
2nd I do not own a Hatteras M/Y. I have a close friend that does and
he is also looking at another 27 that will be going to the Bahama's.
3rd. Having two 27's side by side is kind of unique!! Not something you
see in the wild every day..:cool:
There is no doubt they came out of the same mold! :D
If and when the 3rd one shows up, it will be history in the making..

Hope this clears the air... :)

Thanks again guys!!

PS: Don, Kenny's buddy tried to do the eBay thing with your brother!
It was a dead give away by his eBay name! :eek:

How stupid am I?
Cheers,
Us.

Kershaw is sick.

Nobones that 350 yammy will be stolen quickly in the Bahamas. Food for thought.

Ken,

Too bad it didn't work out, they are in Stuart coming off his boat on their way to AZ.

Seeya

Hey Ken,

My buddy is in the same boat (Literally). Please let me know what you decide. He picked up a 1986 27' Center Console version that is listed at 5000.00 lbs dry. It currently has Twin 1999 Yami OX66 Fuel Injected Engines on a bracket that run fine with less than 400 hrs each. He is going to keep the Engines for the upcoming season, but was thinking of re-powering if he likes the boat. My thought was a single 300 Etec at about 540 lbs. My thinking was my 27 has 350 Diesel HP (At the flywheel, Lots of torque and Huge Props). I have plenty of power for what I do. I can cruise at 30 Knots if I push the Engine to 3100 RPM. I usually cruise at 2700-2900 at about 24-27 Knots and I top out about 35 knots loaded, was about 37 knots empty at 3500 RPM (My boat weighs around 8000lbs). There are few days up in the NE when we can cruise above 30 knots, yesterday was one of them. Anyway, I figure my Engines weighs about 1800 lbs, Engine, Jackshaft and DPH drive. He would have 300 HP (At the Prop) and less 1300.00 lbs of added weight. He is pushing 500 HP, the boat flies, close to 50 knots. Take away another 530 lbs (one 250 OX66) and the drag associated with it, and shave the HP from 500-300, it should have similar performance as my boat, maybe better. I was thinking close to 40 Knots with a cruise around 25-30 with decent fuel economy. I figure the 4-stroke would work too, but just a little heavier. I realize the Engine will work a little harder and will use some fuel, but it should be fine. Not a rocket ship, but decent. He will be taking up to Six Passengers, but just off Chatham and the rips below Monomoy, from Ryders cove and Maybe an occasional Tuna trip in close.

Bottom line, I think it will work. I hope you do yours first (LOL) Good Luck

27 with a single

I can shed some light and perspective.
My Flybridge had a bravo 454 310 hp.
I did some reading on a similar boat weight with a single etec 300.
On my 27 i believe the single etec would be an advantage- set back on a bracket;
Running in cleaner water 10-15% advantage(what ive heard over the years)
Weight difference- 800#s lighter tha 454 with I/O
Advantage of two stroke vs 4 stroke two stroke delivers power on every piston stroke.

My concern is load on the lower unit gears.

No problema pal, I'll respond to anybody... Jimminy Kenji-san,freakin ladder slip mellowed yer a$$. Seems just a couple of years ago you'd a been standin' in front of that fish killing thing with a BAR, tellin yer kids former friend to get off yer propaty:eek:. Missed you guys at Anclote. Catch you at cayo costa or whatever. Be a little more insistent on opening pubs on Hump Night... Cheers.

Ken-After seeing that 27 hull of Kenny's friends in person here in Bradenton, It is very efficient looking and with Fr Frank's comments about the Bahamian Defense 27, it sounds like the 350 would work, twins sound better though. Very cool boat.
