advise needed on engine size for a V20

[nipper]

It was a brand new engine on ebay with full warranty and Mercury's new ignition system--just turn the key and it fires without setting choke. It is really working well.

The place I got it from is NuWave Marine restoration. He does installations too. Real nice guy named Ken is the owner and guy I dealt with. Apparently he buys engine/outdrive packages from Mercury, then separates them and sell the outdrive and the engine separately for a little profit. I think I may have screwed him on the deal I got, because he is now listing a 4.3 Mercruiser engine for $3999 "Buy it Now" only price. His 5.0 litre engines go for $4999.
