Hello, just picked up a new to me boat. It's a '94 with original 454 xl's. I'm confused on what oil to use and the overflow reservoir. I think theynhave sae 40 in them.
Run home was about 100 miles then I did a day last week and ran just a few hours. Boat ran great. Gauges were steady etc. the overflows are empty at rest and after running for a bit they get about half full. should they have fluid in them when cold, are they ok empty? I dipped my finger in the front and coolant was in neck close to the top, so I considered that full. A few friends have told me its fine.
Thanks!
