Last year I changed over to Amsoil Marine Engine Oil and Marine Gear Lube for the best protection in my boats. I've been running Amsoil products in all my vehicles, lawn and garden equipment, & generators, for the past several years. When I saw they also had marine oils, it was an easy decision to make the switch.
