    I will just call ignorance.

    There was a time I would argue, I am long past those days. Probably shouldn't mention that a tuff 28 runs 95.5 with a 525, or the 21 in my garage runs 102.6 with a stock 300 xs.
    The bottom on sutphens are in the stone ages..... Kinda like donzi's

    call it what you want..... if you say that's a stock 150, I call BS

    go here and get back to us with the prop and rpm required > http://www.rbbi.com/folders/prop/propcalc.htm a STOCK 150 has a 2.0 ratio STOCK gearcase, I stopped at 40" prop and 6000 rpm which is the rev limit on that engine if it's a stock Opti-150 or an EFI 150 and it came up with .014 slippage, the calculator won't go past 40" pitch ....,

    however if you stop the video at the 5-6 sec mark, and blow up the pic, you can see that it is NOT a stock 150 midsection, or lower, in either an old cowl or a newer 2.0 Opti cowl, and if you crank up the volume you can hear that it's wayyyyyyyy north of the 6000 rpm rev limit window of either STOCK 150 EFI engine configuration....

    I don't think a stock 150 will turn a 40" wheel, do you?

    correct me if i'm wrong, but there's never been an Action, Hydrostream, Allison, Mirage, Checkmate etc., on record, thats run anywhere near 92 with a stock 150...

    there isn't a single Merc test report in their entire library of hulls that even comes remotely close to that either....

    the video is 12 sec long, are you telling us that that boat accellerated from a slow just on plane rollout to 92 mph in less than 12 sec when the first 3 sec is getting planed out correctly??? that video ain't 92 mph my friend

    not on this planet, with a stock 150

    now, if you have a worked 200 2.0/2.5 liter under a 150 deckled cowling, then I might start to believe this...

    Ugh.
    Why I am bothering is beyond me.

    The power head is a STOCK 150 xr6, it is mounted to a merc 15" midsection with an 1.87 ratio sportmaster. There is ZERO hp to be gained, bottom end power is lost due to the larger exhaust path in the adaptor plate. The power head is carborated, there is no rev limiter, power drops of dramatically after 6100 rpm. In this case the motor was running. 6400 rpm with a 32 pitch lightning et prop
    I suggest you redo your math.

    Btw, it is well documented there are MANY Allison xr2001's over 110 with STOCK 200 powerhead's, they weigh significantly more than this little tuff

    then you don't have a stock 150, nor do you have a production engine that Merc ever produced for *recreational* use, you used parts from 3 different engines or racing parts bins to make a race ready engine....

    I could care less that an Allison runs over 110 with a stock 200, thats not the issue here, you bragged about a 150... and a 200 won't go over 100 with a stock mid or lower either, on any hull...

    I've had an XR6 before, which is why I challenged your claims, it made more than 150 at the prop... noticeably more...

    if your going to come onto someone elses brand website, and bloat your news, then perhaps you should have been more straight up, upfront... about the engine parts stackup

    at 11% slip, I get 92.3.... doable, but still doubtfull, unless the total weight of the driver, hull, fuel, engine, rigging, etc is under 1400#

    hard to believe there's not more slip with a 5" shorter midsection, but hey, stranger miracles have occurred

    don't call somebody ignorant if you haven't been honest up front

    we're not all stupid here...

    enjoy your day

    The powerhead is stock, the mid is 5" shorter to allow the motor height required, weight is more in the 1100 lb range.
    My friend is the builder if tuff, another is the Canadian sutphen dealer, I know these boats well, the Tuff's will run circles around them all. I don't think many realize how small the tuff 16 and sutphen are. The donzi 16 is a lot bigger.
    As for another website, I have a 16/18 and minx.

    The Tuff 16 is promoted at boat shows as the fastest 40 Hp boat "legal for teens" in Canada.

    The boat builder says 90 HP is the max.

    If one buys a new boat, motor, and trailer, I would think that it would be insured. Insurance is hard, if not impossible, to get with a boat that has more than the boat builder's max power.

    I hear that these hulls weight around 500 lbs.

    From the boat builder.

    Length; 16' 10"
    Beam; 63"
    Max hp; 90hp

    In Canada, I understand that those under 16, are limited to 40 Hp, or some such thing. Further, thw Tuff 16 was created to fit within that rule. said to be a 40-45 mph boat with a 40 HP.

    They also make one this size, to get around any USA coast guard rules.

    Length 20' 8"
    Beam 7' 7"

    Looks like a Superboat or a Progression.

    I thought the whole idea of the "Talk About Other Boats" section was to be able to talk about other boats?

    My 16 OB Baby weight ...........

    As a point of comparison the 20' Allison SS 2000 weighs 775lbs

    The tuff 21 started life as a challenger 21, superboats have the original molds.
    The bottom was revamped, different pad, strakes, notched transom etc. And a totally redesigned deck. Then a second revamp of the deck, that photo is of the first generation deck. The 16 and 28 are totally original designs.
    Build quality is exceptional

    Is the Tuff 16 a pad bottom design and what do you think it weighs in at?

    Yes it is, notched transom as well. The weight is around 500 lbs for a bare hull. It is a pretty cool little boat. So Is the 16 sutphen. I have yet to drive one, but soon I will.
