525SC Carb'd vs 500EFI
#11
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.

Not to bad. Rpms stay the same but the rebuilt one is definitely stronger. I have left the rev limiters alone at 5200. My builder said the rebuilt engine is good to 6500 rpms. 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!!

From what the owner has told me on the EFI motors the valve springs were replaced at 250 hrs.
The carb'd boat is brokered and the guy is telling me they are 68 orginal hours, no rebuilds no new motors. Guy used it basically once a year for the last 5 years. The marina ran it once a month and once a year to get everything up to temps. Owner just never had time for it I guess.
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.

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

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

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.
