Anyone know who has the fastest whaler?
What is the speed record?

My father had an early 70's 21' Outrage in 1981, and with a new 200 Mariner, it topped out at 50 mph.

My '92 Outrage (225 Evinrude) turned 52-53 mph (GPS) before I installed the arch. I can't match JFM but my same 22 has done 97-98 mph behind my Yukon. (I'm picking up a new Denali tomorrow night and I don't know if it goes faster than my Yukon or not, but the speedometer goes higher!)

We have yet to hear from the Master of Twin Merc Power! Lhg, where are you? That 18 must top out at 60+.

I have a friend who purchased a used 1988 18 Outrage with a 150 Yamaha. Upon cleaning it all up I read the serial # to be a 200 with a 150 cover. He has never opened it up, but that must rival twin 115's.

Before I installed the jackplate
a month ago, my Sport 15 topped out at 52mph.
My brother is bringing his GPS to the cottage
in a couple of weeks, so I'll finally get
the new numbers (if they changed at all).
Larry could probably enjoy a hot slice of pizza while attaining these"cruising speeds" in a two-foot chop!

62 mph. 1974 Montauk with a 1978 Evinrude 140hp. Not my boat, but my college roommate's. Spent a lot of time on Lake Pontchartrain fishing and skiing. He could take her from a standing position, and goose the throttle and back off several times making her stern dig in more and more every time he throttled. After 4 or 5 times of doing this, he would slam the throttle full, and she would leave the water. At the time, it was a blast. Now in retrospect, it was probably way up the list of stupid male tricks we all did at the time.

I still do that with my Montauk. It is a blast. The 15's did it better. Could literally get the prop out.

LarryS - I'm in hiding, for fear of being put at the top of JB Cornwall's bad guy list.

I think he's over that issue at this point. You could always create a new account, perhaps "Optimious Maximus Whalerus Horespowerus."

My 1986 Outrage Cuddy with a 200 HP Yamaha does around 40 knots (45 MPH)in calm seas and near empty tank. Wind chop in the Santa Barbara Channel, my radar arch, bimini top and 120 gal. tank slows me down the rest of the time.

My 1993 21' walkaround runs 57mph (as indicated by a Raytheon fish finder) with a 225 Evinrude. Haven't checked GPS speed yet.

Talked to a guy in Mich. that has a 1998 23' Conquest for sale with twin 150hp merc's DFI's claims 58MPH. Regards, Jay

Personally I would not want to do much more than 50+ in any whaler. They were not designed for top end. Even though you can push enough power to make anything fly, 65mph in my Baja is downright scary. Hull speed is also designed into a boats shape.

For instance a 17 with 50 will do mid 30's, a 100 will do mid 40's(takes 100% more HP to get a 29% higher speed. With a 140 it might do mid 50's. This is a 57% speed increase but took almost triple the power of the 50hp. In reality I doubt even a 200 would get a 17 up to 60mph, I think it just would not go that fast. This is also why it it not that dangerous to overpower a 17 to a 115 but also not very necessary.

I had a friend install a 420 hp bigblock in a 20' 4 Winns because they thought it will make them do 75 because they now do 58mph. They hit 60-62. why? many factors. On a 12 meter Fountain with twin 600hpSC's will do....say 90mph. It will take a double in hp(twin 1200's) to get to 100. Aerodynamics, aquadynamics(if such a word) weight, etc all play a major role in top speed. Same goes for cars, motorcycles, planes, etc.

Many discussions about this in Powerboat and HotBoat mags. Visit "screamandfly.com" or "scaryfast.com" and look for this subject, very interesting and mindboggling.

I bet your right that a 17 will not do 60 mph with anything mounted to it. But the reason I think so is that it would flip before it got there. I know when I get close to 50 there's not very much boat in the water. Any faster an I think the hull would start acting like a wing. I know I can't got WOT into any wind as the starts to feel like it wants to fly out of the water.

Yup!

I knew there would be skepticism, but I was there. We took a running start, on a measured mile course and measured the speed with a stopwatch tachymeter. Lake Pontchartrain was like glass with absolutely no wind. Since, the hull is a planning hull, theoretically, there is no hull-speed. Obviously, that comment exists in a vacuum, because I agree there is a point of diminishing return do to increased weight commensurate with increase in horsepower. A probable factor is that the '78 140 Evinrude probably weighed the same as the smaller engines in the 100-125hp range.

All of that aside, it was idiotic to try because the boat was about as unstable as you would imagine. When our heart rate got back to normal, we realized then, that the smallest ripple would have caused a chine-walking wipeout that would have made the "Wide World of Sports". As I said earlier, "stupid male tricks".

Too many variables with measured mile, etc, current, wind, accuracy of measurement. GPS or I don't believe. That is my main skepticizm plus the prop Hp on a 78 140 is probably equiv to todays 115. My friend Eric had a 140 Rude on a 17 in NJ and it was sick and highly unstable, especially on turns.

57 mph is stable and very pleasurable in my Hunt-designed Walkaround. In fact, I think I can coax 2-3 more mph out of it with a jackplate...

Jeff - I'm surprised your 21 Walkaround with the OMC 225 is so much faster than Backlash's with the 200 Yamaha. I think Steve's will only do about 42-45.

For others who may be interested, my 25 Outrage runs completely stable at 60mph, or better. The 18 Outrage will handle that speed also, but is a little squirrely with the twin non-CR props.

Larry, I didn't think you could hold out forever (you did hold out for a while though; I was starting to wonder).

And Jeff, I also am surprised about the speed you're getting with your 21 WA; must be the perfect combination. (And it is a really nice looking boat!)

I don't know if he's still around, but Marc Ouray (forgive me if I mis-spelled it) who posted a question a couple of weeks ago about some hull damage he'd suffered on his Outrage 22 from a Louisianna oil rig leg, was telling me about having twin 200's on that 22 a couple of years ago and how it would just about kick itself right out of the water when he mashed the throttle...I'll bet Marc had a top end with that set up that was respectable! (Or irresponsible, depending upon your perspective ;-) )
