Anyone Mounted a Verado 400R yet?
 

Selling the 300 ZUKE off my Boat and i am wondering if anyone is has Re-powered with the Verado 400R yet?

The weight is the same as the 300 and 350 Verado and 20 lbs more than the suzuki.... So i don't see weight being an issue....

The question is at what speed will this Hull start Chine walking bad? I know the magic number on the Formula 233 is 58mph to 60mph.

I am seriously considering the 400R right now since i have to tear my boat apart and fix a ton of stuff that i thought was already done....

Thoughts or Feedback besides I am Nutz?

Robert

I used to run a 23SF with twin 225's on an Armstrong bracket....it started to chine walking at 60!

I know of a 23 with twin Mercury 300xs' on a bracket doing 80mph

A member?

300 diesel would be real nice

Do I see that correctly? 300kg which equals around 660 pounds....yowza. However they are talking about 1200 hour service intervals......and over 3 times the engine life. And if ya wanna go crazy, you can siamese two engine modules and push 700 hp. Might be a rather tall cowling.

Thought.
You are nutz.

Feedback.
Congratulations and welcome.

Why do you want to go 58 - 80 mph?
Are you going back into the ocean racing circuit with your SeaCraft?
Can you handle your hull safely at that speed if it chine
walks?
Do you have unlimited funds to afford the fuel & maintenence costs of such a setup?
I'm just trying to understand your individual mind think....

I like 3700.

My sled had 500 ponies glued to the back of it and it was as pointless as a battery powered paper weight. It has to nearly flat to run these hulls over 30 knots, especially from the helm of a Tsunami. Potter 23s are not race boats and don't fly well but if makes you feel good to drop the hammer in the channel with 400 ponies at wot, go for it. If it was me I go buy a Paramount 21 superfish or a Fountain if I wanted to look cool and go fast. To me putting that much HP on a Tsunami is like dropping a blown hemi in a Vista Cruiser.

I would agree with Ken! I was running in 3-4 foot seas in the gulf to dig up some grouper last weekend and at 20 knots the ride was so comfortable I could have taken a nap in the helm chair. We got passed up by a go fast boat with guys bouncing out of bean bags all over the back of the boat....not my idea of a good time......

24 knots with a little tab is pretty magical in the 23. Great fuel economy, ride and stability. Certainly the sweet spot speed in real world seas.

Spot on Moose!
I ran to Walkers Cay 105 MI out of West Palm. Loaded with fuel,equip & ice. 2'-3' seas all the way on auto pilot in that sweet spot........I miss the ride that no other hull can match :o

Right on
 

The only guy that get's more right, more often then Kmoose, is Santa! In fact it looks like they came out of the same mold.....!
Wait a minute. Now ya' got me think'in - Maybe he don't spend his whole time at the North Pole. Maybe he's slipin' and dogin' around up near Ocala and takin a spin out in the Gulf every once in a while in his Seacraft. And now that I think of it Kmoose always refers to his Sceptre as his "Sled". An if there was ever anyone who would qualify as Ms. Clause, I'd be Mel.
So anyway Ken, jus in case you were wonderin', I been real good this year and behavin' an' everythang. An I ain't put no frogs down Ms. Marsha's blouse, er teased her wit snakes er nuttin'. Jus in case you were wonderin' bout dat.

Robert never thought I'd say this a bout Verados but that's Superlight 400 ponies. that's lighter than a pair of old 2.4Ls . just do it. don't make the salmon wait. get 65 to 70 mph & get up and down the Snake and Columbia in a jiffy. Just beware of the big venturi around the Dalles. Like kmoose suggested, these boats are not designed to fly. Dem little strakes on the pointy end ain't really aleron. If you have any spare change I could use about $10k to update my little boat.

Merry lake x mas:D...

What's wrong with a blown hemi in an Olds Vista Cruiser? Sounds like fun to me.

Without making a radical change in the shape of last 6' or so of the keel line, there is no way to stabilize the hull at 60+ with only a single engine, and with twins you'd still have to be da&^ good on that helm. Chine-walking a single outboard without a flat pad on the keel running from the transom forward always leads to one of two things: getting scared and slowing down a bit, or losing control.

Remember, the VDH hull HAS NO HORIZONTAL PLANING SURFACES! When you get the hull up on to the center V section alone with a single engine, and with the rest of the hull out of the water, it becomes hydro-dynamically unstable. That's just physics and is unavoidable.

If you want stability in a SeaCraft hull at 65+ MPH, you need to modify the hull keel line, run twins with K-planes, or add hydrofoils and become foil-borne with the hull out of the water.

I've rigged a single 20' SF to go over 60 with a Merc Bridgeport, and it was extremely squirrely; no, dangerously squirrely.

Like so many, I LOVE the ride of my 20' Seafari offshore in 2' seas at about 17-18 mph. SSSMOOOOTH! No jarring my back, and I can ride sitting down.

Just because someone has done it doesn't make it a good idea..... ;)

me 400 poundar 2 nd cousin julie was mounted by herd o
mantezein florada

Spidey, where in the hell did you find that article, my God how pathetic can a manatee be to have such low standards!!! :) It's pretty rough when she outweighs the manatees by 100 lbs!!

I'm now going to clean up my shirt from the scotch I just spewed all over the place! :)

mr don i just as shock as u wen 2nd cuz julie tells me bout seacow
mountin her 400 pound big butt
i spilt my bud lt on my britchers
god only nose if she wuz impregnated

What a way to go....."Manatee Gang Bang"
Now the Libs will demand free Chasity Belts for women over 300lbs

Wonder what the flag at the lifeguard station looked like?

The visual is making me head straight to the safe room..:p

I heard she was banned from the TECO Manatee Viewing Center here in Apollo Beach. It was not so much for the endangerment of the manatees, it was more protection of a bad visual for the young kids on field trips having to see her in the water. :)

Moving back to topic...

Is there any reason a 23 Seavette with a 502 I/O (about 450HP) wouldn't chine walk at 65+ but a Sceptre/Tsunami would?

Following that logic - why would a 400 OB on a bracketed Tsunami chine walk?

Weight of the BB low vs. single OB higher and farther back?

I'm thinking if the 400R doesn't chine walk then why not? The western rivers are great to go fast in (unless you hit a log at 60) but with the 400R he could let the engine loaf at 40-50.

Sorry, the idea of mounting a 400 verado got mixed up with manatees mounting a 400#er!! Our mistake. :) I'm blaming Spidey.

Anyway......Not sure if you saw the video of a 39' Seahunter running wide open with four of those bad boy 400hp Mercs in calm water, a smooth 70 mph.

That is part of it I believe.

I also believe boats start to fly.
There is a reason they allowed race boats to cut down their hull sides and bring the pointy
end down in the 60`s.

When you have wind affecting the topsides and water affecting her bottom,
well things may look like a manatee gang bang.

i sorry me jus sea "mountin 400" cude onle think of 2nd cuz julie
wit seacows nockin da bottom outa her
promis to stay fokus
merry chrismas

Nothing wrong with a little extra power....

Not that you're looking to run WOT, fully trimmed out so often, so the motor should run real easy and provide great speed cruising.
