More BS about going fast....

Current Prop is a Quicksilver 14.8 x 21p. 5900 RPM limiter 58.1 mph
With the setback I have the motor as high as it will go and maintain water pressure. My spare prop is a Tempest 14.5 x 23p and is the fastest prop I have, light load turning 5900 rpm 60.1 mph. The motor is a stock 250 XS Merc. I think 250 is about where it is at for hp. The old 250 EFI had a better power to weight ratio so it was faster, retired because it used twice as much fuel. The best I ever saw was 63.1 upwind, down current with the 23p Tempest on the limiter. It dawned on me later that I could have had a 2 to 3 MPH current that day..

None of these top end numbers are very efficient, lots of prop slip. My MPH could be much better if I shed the T-top and baitwell/leaning post combo. That has got to be costing me some efficiency.

Might even go faster if you jumped overboard to reduce some weight after getting it fully trimmed out ?
 
Definitely faster without me.
300 has been considered.
Wonder what a 280 would do with the right prop? That would be interesting especially with 2 hung back there.. Hang em right on the transom. I am fairly sure twins would negate the effect of the round keel and reduce the propensity for chine-walk.

Spare, 2.4 what? Twin Bridgeports would be ERA correct.. Cool would be the Twin Towers of Power 1500xs.
 
I keep wondering what twin 1150's would do (knowing I could later swap in bigger powerheads) but honestly I think I'd rather just have a much more modern engine even if I didn't get as much top speed
 
Ridge, you said the boat ran 48 with teh 2.4 200, what prop were you running on it at the time?

BTW, if stumble across a twin of my brown stripe 200, i might have to get a bracket and run the pair, it would be fun. Marc posted some video of his Seavee running across the harbor running round 70, those choppers he's running make a nice rooster tail
 
17P Quicksilver to about 6100 RPM 48MPH IIRC. (Don't tell Ozzie) I posted it way back when.. 5800 with the 19p Quicksilver at about 46mph. The motor was sound when he got it. LOL!
 
my V showed up with a small ear 21 on teh 2.4 200, I've never put the boat in teh water, I'm curious to what it will run, if it doesn't run fast enough, I'll throw another motor on it
 
I just ordered a NOS 150 shot for the E-TEC---

Figure the way the hp vs speed is working---should be able to switch from my 19p to a 23p chopper and hit in the neighborhood of 70+


:laugh:
 
I think a Superboat would run 70+ with my current engine. Looking for a cheap interesting go-fast hull for the 250 I have in the barn. I been down the Nitrous road Genie. Word association = Pistons. The first time you mash the button and nothing happens because your tank is empty, Waa Waa Waaaaaaaa. Exhilarating blast for sure, let us know how that works out. Pics too if you please. Hell you will probably be too busy cleaning fish to do the install, we understand.

Spare, just go ahead and build the twin powered 20 you know you want to.

BTW- Nearly a complete derail but-- Anybody got their eye on the Louis Vitton/America's Cup boats. The new style hydrofoil cats with the semi-solid wing. Holy crap I bet that is a rush to have a 14,000 lb boat rise up on the surfboard size foils and utterly take off. They are doing 40knts in a 23knt wind ?? Talk about using leverage to harness the wind.
 
Marc was talking about selling his super boat the other day. He took it out for a spin, hit 86 with the home brewed 300 3.0l. Said he's gonna keep it now
 
I would not do nos--I learned many moon ago about that--lol=$$


I am way to happy the way it is--if I want to go that fast I will go out on my buddy 38 fountain--103+--crazy
 
Last time out, yesterday actually. 7 people, 50.6 MPH No way to get the nose up with 4 people sitting in the bow. With all these people she was a pig. Don't everybody go to the same side at once now. LOL. On the bright side, with all this weight the V does its thing above average, crossing wakes and such. Cruising was 37 MPH at 4200. Fished four over the weekend, or salt water catfest as I like to call it. Rainy weather has the Suwanee flooded. Scalloping wasn't gonna happen, water was stained and murky. Swimming was a success and we ate a lot.. good stuff.. Limearita what?
 
Spare do you have that vid of your buddy's SeaVee?

Ridge, what kind of go fast hull are you thinking? I cruise craigslist all the time even waaaaay outside my local area, and love finding cheap and interesting deals. I could be on the lookout for you. I have a knack for finding stuff.
 
Bradford, I don't have a preset disposition to any one length brand or even hull type. I am looking right now, trying to get the house paid and a youngster raised. I like fast but have seen how easy fast can turn sour, accidents happen in a split second. Maybe a Trawler. You got a Mckee or Whaler I can pick-up cheap for a tender?

I love trawlers...especially the ones with a sail in the middle. Give me enough money, one of those boats and I'm off around the world. It's not on my bucket list, since I can't even think of affording it... but it's certainly on my "if I had a dream" list. Maybe if I hit the lottery... <sigh>
 
i worked on a 58 Offshore the other day, I can say, it was pretty nice. The fast trawlers (Offshore, Fleming, Defever) are my kind of ride
