I recently got two boats one is a 1989 Seville 19ft with a mercruiser 165 4banger (aka the 470) and one is a 1974 searay srv-200 19ft with a mercruiser v8 228 mcm. I have a few questions. First is the 228 a upgraded engine? Secondly what’s the weight on the 228? I am considering swapping engines...
