I just bought a 2001 21' Milan boat with a fuel injected 5.7 Engine. I was happy to see it had the remote oil filter option, because some boats are a bugger to get to the oil filter and I hate the mess in the bilge. I have always used like a trash compactor bag to catch the filter and oil. So I'm looking at the filter, which is upside down and thinking how much is going come out of this. I thought maybe sucking the engine oil out, it might be dry. Not a chance. Even though I had paper towels under it oil was all over the place. What were they thinking. I even thought maybe it was mounted upside down, but there is no other way it could go. I'm thinking of getting rid of it and going back to the original location. Anyone else want to take a tire iron to the guy who engineered this? Dave-R

Usually it's less messy if you punch a hole in the top of the filter first, then suck out the engine oil. Any left over oil will drip some but not as much as you'd think it may.

Place some rags all around down under the filter base area, then have something such as a coffee can ready right next to the filter base and without tilting the filter if possible, just set the filter inside the coffee can then clean up any oil that may have ran down the sides of the filter base landing on the rags under.

As little as you change the oil, it wouldn't be worth the hassle or cost to change to another style because they all leak a little (Sometimes a lot of) oil when pulling a filter on just about anything you do, cars, trucks, etc....Sometimes even more than the upside down filters.

Once you get the hang of it you might even come to liking the idea altogether.:D

Enjoy the new boat!!! Still have the Cobalt too?

the remote filters were designed for the ease of the motor's installation and for service points when being reviewed. not actually for ease of boat ownership.

I use a lot of paper towels and sometimes slip a plastic bag under/around the filter as I loosen it, just before it it starts leaking. I usually have a bucket right there to toss the whole mess into. Then another set of paper towels to keep the drips off of the exhaust manifold.

I think the issue is that a few ounces of oil stays up in the fitting area of the housing . . . so once you break the seal by loosening the filter, it all come out.

Still better than having the filter down below though IMO.

You are my new best friend! I said exactly this about 10 years ago when I bought my MPI. "What moron designed this?"

Best I can offer you, and it's what I do.... Warm it up, drain/suck out the oil, leave it sit overnight and then replace the filter. It's drained down by then. Either that, or unscrew and flip it up the 'right' way really really quickly. :D... (or lots of very absorbant cloth rags jammed around the base of the filter :facepalm:)

Mercruiser remote oil filter

I just bought a 2001 21' boat with a fuel injected 5.7 engine. I was happy to see that it had the remote filter on top of the exhaust manifold that was easy to get to. I always have dreaded changing the oil filter in most bilges, because they are usually a bugger to reach, and I like to put a pan under it or put them in a plastic bag. I hate the bilge looking like a bilge. So I'm looking at this filter, and it is upside down. I'm hoping it's like our Subaru and drains when I change the oil. So I stuff paper towels around it just in case is does not. It doesn't. Oil all over the engine and the bilge. It would have been easier and cleaner to take the remote filter and all the hoses off and put the filter back in the bilge. What am I doing wrong? I have a good vacuum oil pump, and I was thinking it would pull oil from the filter. Will it drain if you wait a while? At least my Volvo Penta engines had the filter with open end up.

Dave-R It unfortunately appears you may have misplaced your original topic regarding the up-side down oil filter with creating another topic regarding the filter tonight. I took the liberty of moving your new topic into your original topic to help keep things altogether. Summoning your username should help you locate your original topic easier.

I just wished you would have found this topic before you changed the oil filter to try and help avoid the extra oily mess you encountered as usually poking a hole into the top of the oil filter helps slow that mess up.

Thanks Funtimes, and yes I still have the Cobalt. We took it Lake Powell a couple of times, and it ran great. Before all you guys get old like me ,take a few days to see lake Powell. Thanks to you and the rest of the i-boats guys.Next time I will both punch a little hole in the top, and wait overnight. Dave-R
