If its a true 68 hours boat I would go that route just because everything only has 68 hours on it. ( Out Drives, transom assy,,,, steering,,, trailer should be in better shape )

Cold day just means you have to let it idle up a touch longer,,, wouldn't think twice about it.

And if you ever decided you wanted more,,,,,, its easier to play with the 525 SC,,, than a efi motor.

Then it comes down to condition , and colors preference,,,,,, neither boat would scare me reliability speaking.

When I get the other engine to match I might increase the RPM limiter. Will have to consider chiller possible and the RPM's of the 177's on top. Overall, and to be completely honest, I just love the blower wine when it kicks in!!

As far a resale goes not a huge priority. Hope to have this one for awhile. Both are priced the same but I think there's more wiggle room on the carb'd motors. I like the way the carb'd boat looks better then the EFI, hate to say it could come down to looks but I also worry about stretching my summers and those cold days for carb'd motors not always fun.
Actually you will learn to love cold days with those little blowers

VoodooRob makes a good point, what are the boats that you are looking at? That could be a factor as well

99 Donzi 38ZX
00 Donzi 38ZX

As far as I can tell they both have the same hull.

If you can find a mechanic that has a rynda tool with a adapter harness for the thunderbolt 5 ignition you can pull the hours out of the modules,if they only have 68hrs should have a lot of life in them,i have seen several sets go over 500,they will burn more fuel than the 500efi but were good engines that are easy to work on

Agreed. 68 hours, that's like a new boat as far as the rest of the mechanicals go. The 525sc is a little stronger than a 500EFI.

Glad your not looking at the 38zx 525sc that has been advertised for a very long time in Cleveland. Since hulls are the same just different colors on the 2 on your list, my choice would be the 525 boat.

After looking at the pictures for awhile longer, I would definitely go for the 525 boat. Cannot beat the condition and hours for the $. Let us know when you snatch it up.
