I have 365 magnums and was under the impression it was 6 quarts with filter. Changed oil and checked with 5 quarts and dip stick reads full. Boat is on the trailer and is level. Should I put the 6th quart in?

I'm sure I have it all out. When I pulled the engines over the winter I installed the hose kit on the drain plug. Makes life alot easier. I guess I'll just order a dip stick and try that. Thanks for the input.

I have the hose drain kits on mine , and they also leave some behind
Initial fill on mine was 12 qts. First change at 5 hours and 10 qts filled them , due to some left in pans , oil lines and cooler,

That would make sense. The more I thought of the dip stick being wrong it's odd that both of them would read the same. I checked the tubes also and all semms fine. As "too old" said, use dipstick to determine.
