350 MAG w/Bravo III
Spring is here and everyone is getting excited again about boating (at least here in the North). What is the fastest speed you have recorded in your boat? How did you measure it (GPS or speedo.)?

In my 180 sport I have hit 43/44 MPH (as recorded on the spedo.). I will be installing my smart tabs soon and they claim to increase the top speed by 2-4 MPH (we'll see).
 
185 Sport 3.0L - 40 Mph (GPS SOG) (Boat speedo says about 44)

That was before I installed Smart Tab SX's and I have not checked top end since the installation.
 
IN my 240SD 350 mag B3 I've hit 49 (GPS) but the wind was at my back (a good wind too) and it was a cool day...just me on board and about a 1/4 tank of gas...
 
41 MPH full fuel and water, 1-2 foot chop. Scanned props.
 
46mph (GPS)/4500 rpm with clean bottom and smooth water. (repeatable in May/ June)

35mph / 3600 rpm with fouled outdrives and barnacles on the props prior to haulout. (repeatable each November)

Last weekend, I saw 32 mph / 3000rpm with light rain, 3-4' wind induced chop (short period) and a 30mph headwind. Boy was it a cruddy day - - > I was getting bounced around too much to push the throttles harder
 
Last year we got 51 (gps) with 2 adults, 4 small kids, half tank of gas.

We were on a smooth inland lake. We will be taking another gps reading this year with just my wife driving with 1/8th tank of gas. Just to see what it "could" do.

We were able to get my 250x up to 68.1 (my wife was on it at the time). It is stock right now, and I believe with the riva ride plate and a 2 degree wedge I could easily get another 2mph out of it.
 
I got to 45 MPH verified via the GPS last year. This was with my wife and 3 kids onboard plus we don’t travel light.

I took a class in the off season. The class had nothing to do with my tabs but I think I’m smarter so maybe I’ll see some performance gain. :smt043
 
55 mph on my 185 BR Sea Ray w/4.3L motor(via speedo) Only been to 4100 RPM's or so this yr on my new 210 Select last Sat. Didn't want to open it up with 40 degree water, and about 1' waves, and it's low hrs. (only 13.6 so far). I'll update this as it gets more hrs and the lake warms up and I get a smoother day.

With a newly painted bottom, freshly scanned wheels on smooth flat water with no head wind or current a little more than 30 MPH on teh GPS at 4200 RPM burning just under 50 gallons per hour which is like 8/10th a gallon per minute which equates to $3.20per minute at $4 per gallon or just about $0.05 per second. Needless to say I have done this for about 30 seconds each season. Normally lug around at 3200 RPM and 19 knots at a very economical 30 gallons per hour or "only" 1/2 gallon per minute for $2. Man I wish I had not done this math. Actually having the boat tied to the dock with the unlimited unmeasured shore power that is included with my slip is ideal.
 
the 300 DA hit 61 mph, no one in the boat, empty tanks, drives all the way up verified with a GPS! It's a lot slower in the water.
 
Sundancer is correct. Corona del Mar made the trip from the West Coast of FL to my prior home in NC behind a Freightshaker doing an easy 70 mph up I95 and then again behind another Freightshaker on its way from NC to NJ when I moved back home. At the time I paid I think about $2.50 a mile for the move and that included all the over wide permits, much cheaper than the cost to move it a mile on the water today under its own power. Of course back then diesel was about a buck fifty a gallon!
 
60.0 GPH verfied by multiple sources.

That was at just above 40 mph on GPS, slack tide.

I had a 1989 Classic 190 that did over 60 mph on a regular basis - 305 V8 w Alpha Drive.
 
2006 240 Sundeck 350Mag 5.7 w/ corsa exaust two people 1/2 tank of gas 49/50 GPS. Water was calm.
 
appx 54/55 according to the speedo.

Early morning, nice clean river, almost glass. Only for less than a minute as I am at 8.5 hours on the engine. Was a tad under 5k tach. 19 pitch prop, I am wondering how a 20 or 21p would be...
 
45 mpg based upon GPS readings... wife screaming something about fuel but it was too load to clearly understand her :)
 
44-Speedo.

175 Sport with 3.0merc

That was with the stock 21p prop.

Now, its like 38 with 17p 4 blade.
 
My '91 180BR had a 4.3L Alpha I on it. Funny how they don't offer that set up anymore as it may have been dangerous. By myself, 1/4 tank WOT speedo fluttered at 60.
It had a High Five prop, but I forget which pitch it was.
That one flew. My 230OV was quite a bit slower. It had a top speed of around 46.

This beast isn't as fast as DaveS's 100mph nitro burning monster....SUNDAY..SUNDAY..SUNDAY!
