what kind of hours can you expect to get in 28zx twin 350 mags year 2000. looking at 1 for my buddy it has 440 on it now what have you guys seen for hours without problems. also how does the 28zx work with this set up as far as handeling, speed, any porpoise or chine walk. Thanks

350 mags? I would guess anywhere between 600-800 hours would be realistic depending on how they have been run. You should be able to scan the ECU to see how long at what RPM.

68 mph would be norm but friends tell me they get just north of 70 on a good day. They don't have any handling issues. Rock solid little 28.

I have a 99 with 350 mags, I get 69 - 70 most days speed pretty much the same with a light or heavy load.
It will chine walk a little but easy to control with stearing, just takes a little seat time.
