Donzi 26zx with 2inch shorty ??
 

Hi there,

i own a donzi 26zx 1999 model, i was thinking of a 2inch shorty lower unit, and was thinking of any views tests etc from you guys, the hp is around the 650hp mark, top end rpm is 5800 and i can hit this with a 26p b1 labbed prop with the stock lower and get 78mph on gps.....

any guys have any experiences with shorties on this model ? what would my gains be with this new setup ?

thanks

The 99 is stepped right I beleave that was the first year. I have the 33zx and wanted to do the same thing eather with shortys or -2 boxes....I was told it would be a wast of money for me. I gess they r set up good from the start. That is what I was told..

yeah its got the same ztech twin step hull.......however x dimensions were set up differently on each model i was told

where is your propshaft now in relation to the bottom of the boat? does the prop blow out at all getting on plane?

In back to back test at over 90 MPH, the Imco lower was +2 MPH vs. the standard Bravo lower at the same prop shaft height. Straight vee...no steps.u

unless the person your are talking too has this hull dont listen to them,, theirs a member on here that had one and it was all dialed in,,ran 103 mph but it was a crazy ride getting it their..the members name you want to ask ? to is bill,, ZXXX Donzi is his screne mane...
good luck

DonZ,
All boats will may respond differently. Our experience is there is speed in the Imco lower at the same prop shaft height as the Bravo I lower....even vs the Bravo XR lower. You have to test YOUR boat to know for sure.

i now Bill Patterson very well, i have spoken to him, i just wanted to see if anyone has tried a shorty, Bill is very knowledgeable on that boat as he went over all the hurdles i believe and most probably owned the fastest 26zx on the planet, thanks again for all the info guys, will let you know once i have tested one, this will probably be in March time just to let the weather get better, all the very best for the holiday season to you all

I have the 26zx that zxxx had. Pls let us know if the shorty works, tks

its not the same boat it use to be,,bill bib not want anyoene to kill themselves in it so he put the stock engine backin it before he sold it,traded it..

That's correct, but that stock 502 has also been replaced. It'll run in the low 70s now. Doubtful this boat or any other 26zx will ever reach the speeds Bill achieved with this hull.

I am closeto finishing my1999 26ZX project and have yet to put the boat in the water or ever drive this boat. I have a B1 drive 1.5ratio with a Bravo 26P and around 550HP and I am interested in how this works out for you. I built my engine with aluminum heads,intake, ex manifolds and saved about 200lbs of weight right off the back of the boat as compared to a stock 502. I am wondering how much of a difference, if at all, the reduction of weight will have on how the prop sits in the water? Once I get a feel for how the boat handles I will be looking at a shorty to see if it would be a benefit for me........ I would think that the faster you go the more benefit you will see?

Are the 22 classics more stable with similar power/set up? Just askin' :D

i cant answer that question,,i have a x18 and its a handful...but thats gue to no hydraulic steering...i see the members on donzi.org ans net that are in the 80's and 90 mph range that have no issues at that speed..i think it has to do with the ste[ed hull and the boat only haveing a singel engine.once the boat hits mid 80[s you have to watch it going over waves...

Tks for the videos. I would like to get it a little closer to 80, but it might be for sale soon. Trying to move up a little

send bill a im and see if he will sell you the procharger that was on the boat,,that will put you close to 90..
