Carbed, 2004 & 2005 so both stepped. My preference before finding the one with 650's was EFI but I like the 650 boat better in a visceral sense. So while trying to establish some value on both engines, I'm now throwing carbed engines into the mix and trying to see if that is really an issue worth worrying about. From my research on previous threads on Zul engines, I shouldn't be too concerned.

I had 800 Zuls in a Gladiator - sent the carbs to Nickerson and they idled good considering the big cam. Ran real strong, best sounding and best looking engines I’ve ever had. |
I don't think who built the engines originally means much once they've been worked on by other people. I've looked at engines before that were "Zul" engines. After some questions come to find out they've been rebuilt by some different builder. Well then they are now the engines of whoever rebuilt them last and the name on the valve cover is pretty much meaningless. The same is true of the Merc engines. So how many builders have touched these engines since 2004/5 ? You're talking 14/15 year old engines here. Even if they are newer, who else has taken them apart?

Unless you had bought 2 new complete 525 efi long blocks from Mercury Marine.
They even came with the valve covers. I think but don't recall if they came with the intakes. Just install your exhaust headers, alternators, water pumps, distributors, etc. That's what we did on The "Lucky Strike" F-2 38 T/S Top Gun. |

Much like resale red for Ferrari’s.... resale blue for merc blue racing motors...there isn’t a close second. |
