I just bought a 2016 Four Winds with a mercruiser 4.3 L MPI and an alpha out drive. I have an owners manual for the four winds, but it says to check the engine owners manual for the engine. I do not have an engine owners manual north of been able to find one that doesn't look like just a brochure. Does anyone know where I might be able to download one? My experience is primarily with outboard motors so this is something new for me
