Read somewhere once that multi-grades contain detergent which is bad for marine engines, never really understood that. Maybe someone higher up the payscale could explain it to me. Plus, I`ve always owned boats 20 to 30 years old, maybe that has something to do with it.
Most all single grades contain detergent . there are some non detergent oils out there . but they do not even come close to meeting the needs of your engine . more suited for compressors and pre 1950/60s cars . Most likely the oil your using contains detergent

Dunno. All I know is that the PO always used it, and they purr like kittens. He was also a 3rd generation waterman, and the sales manager for an oil company. I used 20W-50 in my Harley too, and my BMW GS1150. I think it is a nice compromise.
