22 DCB Speed with Single 300 or 300x

[zcrazy]

Just wondering what kind of real world speeds you could expect to see out of a 22 DCB with a single promax 300 or 300x, anybody with feedback that would be great. Also what prop and rpm.
Thanks

Just a guess here but 21 Liberater st up right will do right at 100-103.
I'd say a 22 footer would clock in the 90's set up perfect.

Mach 22 with 300 Promax....Low 80's.
Mach 22 with 300X...Mid 80's.
Mach 22 cannot be compared to a 21 Liberator. It's a completely different bread.

my 22 mach with a pro max not an x will do 87-89 light load ect, but otherwise 83 all the time. most fun to drive out of any boat i've ever had. add about 5-6 mph for an x motor

WHAT ???? mine was a SUPER HEAVY 22 with 3 or 4 batteries (cant remember & MAJOR stereo bits and pieces) and with a 28 ET prop it would do 91. mid 80's what a HOMO :rollside: :)
my buddies MACH22 with twin drag motors was low 120's..... insaine FAST!

HAHA Mr. Baller. And how did the ET come on plane and accelerate? How about the vibrations? I've tried them all...26P Bravo 1 is the best all around. It'll run mid 80's all day and accelerate nicely.
I've got a 30 ET right now that is FAST but the 26 Bravo is much better.

ya know.... I think it was a 30ET :idea: been awhile now. It was really fun with two people ONLY. Still rolled over OK, just didnt like alot of weight. had a REALLY worked 26 bravo from R&R with MAJOR vent holes. Was an awesome all around prop and still saw high 80's with it. Miss that boat, was alot of fun.

i have a 26 bravo 1 with vent holes for sale-my talon doesnt like it .send pm if interested

High 80's maybe 90 with light load and cool air + big wheel. Real world with load and havasu heat low 80's

You goin out tonight for the regatta? How bout the party tonight?

Thanks for the info, is it possible to convert the single 22 to a twin 22 setup as well or would the whole transom have to be redone if you wanted to convert to a twin setup.
Thanks

dont know about a single but my dads with twins runs about 118-120 with some lower compression heads allowing it to run on av gas. With the high compression heads on race gas runs about 130. if youre going to do it, do it right and go with twins.

Are those 15 inch mids and are they 260 or 280 powerheads.
Thanks

[robertm]

you know i couldnt really tell you. the motors were off his 97 mach 22, it was supposed to be one of the first ones out of the mold. featured on the cover of ***boat back in the day. they said it ran 130 on race gas. when my dad bought the boat the guy didnt sell the higher compression heads with it. i really dont know a damn thing about outboards other than they haul ass.

zcrazy, Twins are a rush :220v: the acceleration is unbelievable! Just try and lift your butt out of the seat, you'll feel like your glued down!
The only draw back I have found is that there pretty light in the bow other than that I would buy another one.
I think a single would be much more predictable when approaching a cross wave, with twins it wants to launch skyward!
I have twin 2.5 Drags on mine with 37cc heads (low comp) and run 92 pump gas because that's all we can get around here and its still faster than sh*t.
Dave told me also with the 26cc heads and race gas it would run around 130 mph.
Good Luck!

i do agree that the front of the boat does get extremely light and will start to porpus. cant trim it up much passed 2 on the trim guages or it gets sketchy. Tunnel vision what mph have you got yours too run on pump gas and what pitch props are you running. we had 32 clevers on the boat when we first got it and it felt like a little bit too much prop for it. probably would have been fine with the high compression heads on. i believe now it has 28's on it. doesnt cavitate nearly as much out of the hole. still seems to run about the same mph, gets there even faster and does even better on gas.

[23elim]

Not a 22 dcb but a 22 stoker with a 300 vmax and it will run mid 80's

Sweet boat

Nice. The Mach 22 itch is coming once again. :mad:

I would love a 22 with twin 300's for the week time....

Sorry I did'nt get back to you sooner. 110mph/7000+/- is no problem but I want some more seat time before I take it any further.
I'm running 32" Mercury lab finish cleavers, I agree they are a bet too much and make it unable to reach the rpm sweet spot, I would like to try 28's.
My wife would love for me to try choppers because she's only got one leg left after crashing into the cleavers :220v:

TV get a pair of 26 or 28 ETs and call it good. With 26s and Drags the 40mph too 100mph time is unreal.

[Tunnel Vision]

What do you estimate the top speed @ sea level to be, any idea?

Those are 15" offshore mids

I've seen 114-116 with 26s in the low 9k range on the tach many times.
