Donzi 28zx
Hello, just curious if anyone on the forum is running a 28' non step hull with single 502 and what top mph you are getting. I have a 98 donzi zx 28 with 502, I just bought the boat and the owner told me gps was about 65 with 4 people. I took it out this weekend and I'm only getting 55 on gps. Boat has k planes im not sure if these have a factor on this style boat I had the drive trimmed up and the tabs all the way up at wot. Any advice would be great! Thanks

The 28ZX should have a step.
Not the fastest of boats with a single 502MPI. Pretty heavy, crushes waves well. Fantastic engine compartment to work on things. I believe a 23"MiragePlus was standard prop ? Rode in one a million times but never with a GPS. Probably not much faster than low 60's...if that.

Boating Magazine tested speed was 63.7 with a 502 and Mirage 23. They, too, were disappointed (seriously, they said so in the article).
I say tested because I'm guessing they weren't full of fuel with 4 bodies when they ran that number.

P.S., I just realized the test is a stepped 27zx. Cue a more disappointing number for a straight bottom.

Too late now, but sea trail before you buy again, sadly...you can't trust some of these guys. And like the others said, try to get your hands on a Mirage 23, see how that works for you. Good luck!
