Labbed props don't do anything for non-step ZX's.

These guys are right, unless you pick up a bunch of HP, you will only create problems for 1-2 mph. Stay stock or really up the ante.

For a little over 10K I added 200hp to my 27footer and it picked up 9mph with a prop change. leave it alone and put the money in the fuel tank.

Best advice I've heard yet.


I appreciate the help. Probably should just enjoy the boat for what it is.

Thansk again for the advice, I really appreaite it.

that eould be the smartest thing to do! just ask jeremy aka fogducker...he picked up almost 20 mph with a engine refresh and the procharger... and that was on a 454 385 hp efi..

I'll trade you a MEFI 3 with the tune already in it for your Donzi poster. I already gave away the last couple ported intakes or I'd give you one of them too. I'll throw in the fuel pressure reg as well. :coolcowboy:

Is the MEFI 3 what I would use for a 1997 era Gen VI?
