Single Big Engine or Two Smaller ones.
I plan on buying some engines for my 60" Expresscraft MTI Cat soon. Would it be wise to use a single Quickdraw 35cc Engine (7.8hp approx.) or two Zenoah 260's (approx 7.5(ish) for both)

Thanks for the Input

RE: Single Big Engine or Two Smaller ones.
I would go with the quickdraw 35cc. My uncle has a 25cc quickdraw in his boat and it screams. Probably goes 45-50 mph. With two engines I think it would not be good bescause you would have to start both of them. Also you would have to tune them the same. This is just my opinion.

RE: Single Big Engine or Two Smaller ones.
By all means , if you've got the pocketbook for the QD , then geez , get that ! But , also note , that there is NOTHING like the sounds of twins running full bore ;) .
If speed is the deciding factor , then again the QD wins hands down . But , if you are like me ( I have an Aeromarine Systems 60 inch cat with twin Zen's ) then , the thrill of the twins is uncomparable .
Also note .... although I do not know all the rules and such for the clubs ( IMPA , NAMBA , and such ) , I am pretty sure that when runnign twins , it puts you in a totally different class than the single QD .
Seems like a "boom" all of a sudden for doing twin cats ( [8D] right after I done mine ? [8D] hummmmm :) )
Anyway .... me , NOT being a racer or even remotely interested in racing , I would personally go with the twin setup ( extra weight , extra monies for hardware and setup CAN be "fun" , but hey , what the heck ------ isn't this what its all about anyway ? Fun and originality ?
Either way , your pockets shuld be pretty deep .... ( both ways will cost ya heavily )

RE: Single Big Engine or Two Smaller ones.
thanks for the imput. I'm still not sure about what I'll end up doing.

What hardware are you using for your set-up? (TerboBOB) (Pics?)

RE: Single Big Engine or Two Smaller ones.
I was pondering the same question, i myself think i'll go with twins, just to see how they are! Now that i have that taken care of, what does everyone recommend for a good LARGE boat?:)

RE: Single Big Engine or Two Smaller ones.
If i had my druthers and was gonna run twins id go with the 231's.
with twins you dont need the torque od the 260's and the 231 is a higher revving engine and more than likely the same final hp as the 260. Yes QD's and J&g's are powerhouses but they can get to be maintanence hogs and will get real fussy if not cared for on a regular basis, these are pure race engines and must be watched over as such.............good luck
