i currantly own a 27'8 donzi zx , it has 502 mpi with bravo xr drive, with a 23 pitch mirage , does anyone know if i can get any gain by using a bigger pitch or a different prop ? would it be worth it ? just wondering....

Takes lots of HP to get that hull to move....have a friend who had on and put a Procharger on it and it ran well....he went from a 23 M+ prop to a 26 inch BI ....boat would toyuch 70 in good water...what speeds are you seeing now? about 58-60.....you shuld post this over on www.donzi.net lots of good info over there

yes your right 58 - 60 ...60 if it is a perfect day ..

That boat needs a blower to get it going. I had one for a number of years. It was a great boat with one hell of a ride. Boost really wakes it up. I would not waste time messing with props and small stuff. You have the XR and 502 as a great base. Add a couple of hundred ponies and you will be much happier. With the current combo you are seeing 58 on a good day. The M Plus is the best prop for that boat with a N/A motor. Forget the 4 blade unless you have tons of torque. I have tried a number of props and combos on that hull. Pm me if you want to talk.

Anything other than boost and you are wasting time. Add some hp and have fun! With big hp, you can go where others fear to tread.
