Hi all, first post on this forum.
Easy questions for wiser boat motor heads!! I have a '79 21 foot Sleekcraft Daycruiser with a Ford 460 and Panther Jet. First oil change is due since I purchased the boat and I'm not sure what wieght oil I should run. Is 10w-30 O.K.?
Second question is, I run about 50mph at 4000rpm, does this seem right? Or should I be running higher in the rpms?
Any info would be great, if it helps I live in the Northwest near Portland Oregon and run the Columbia River mostly. Thanks.
