i have a buddy wit a 33 donzi with twin 454 420,s
its an 87 i believe-it has trs
hes running with 25 mirage plus like 66 mph max
on the greatest day. he would like to break 70
any suggestions with out going to blowers
he would like to stay with mainly bolt on equipment.

is any one else running this same set up at all??

any help would be great

are they stock propellers / THEY MAY NEED A LITTLE FINE TUNING TO PICKUP SOME ACCLERATION IN MID RANGE AND TOP END /LET ME KNOW IF ICAN HELP OUT /WE ARE ALSO CURRENTLY RUNNING A SPECIAL ON PROP WORK UNTIL DEC 31ST /THANKS.

That hull isnt the newer twin step design.So your limited...you can add heads, cam,exhaust props...spend alot of money and go 70...is it worth it?I would sell and buy a newer design but thats me.
