I have a 1990 Mercury 200hp on my 22ft Aquasport. It has a low cylinder. I can get a good deal on a 200hp Mariner. Are the motors the exact same except the name? Is the performance the same? Are the parts interchangeable? The Mariner is an 1989 year. Also should I leave the oil injection or premix? I would remove the oil injection however the boat has a 100 gallon fuel tank and trying to premix would be a pain in the ***. Any suggestions??
