Has anyone out there cross referenced the mercruiser 4.3 oil filter to a reg. automotive 4.3 GM engine oil filter, so I can grab one from the shelf on the next shopping trip? Year is an "06" Also, I have a couple other questions since I'm asking. First, the timing sticker fell off after a couple weeks ( a little sticky backed paper, barely sticks). Will they be able to time it when the time comes? Lastly, where do you find the P/S cooler and why doesn't the owners manual mention about draining that in the winterizing section? (freshwater) Thank you for any answers.
