Is there an easy way to tell the HP rating of a Mercruiser engine? I just bought a Bayliner 2050LS with a 4.3LX Vortec engine w/ 4bbl carb. The owner told me it was 180HP but I can't find anything anywhere to confirm that. The block is cracked on the engine so I'm going to have to replace it and I have a line on a complete used engine from a 1994 boat. The valve covers on the used engine do not say Vortec on them while the valve covers on my engine do say Vortec. Before I fork over the money for the used engine I'm trying to confirm that is is at least close in HP to the one I'm replacing. The plastic cover over the flame arrestor lists WOT at 4400-4800 if that matters at all. You would think they would list the HP there along with all the other data but no such luck.
Thanks in advance for any help you can offer.
