Not really a question here, but more of a mystified observation....

I bought my boat new off the lot, and a while back I changed the oil and filter for the first time, buying the expensive mercruiser oil filter per the manu recommendations... only to find out the boat comes stock from the factory with an AC Delco filter!!??!!

Does that make any sense?

Part of this is a marketing BS thing. It makes sense that GM would have installed the AC filter. And it makes sense that Merc wants their customer to purchase their product!
As long as the filter meets the manufacturer's specs, there should be no issues!

Question: 2008 boat and you just recently did the first oil/filter change? :prod
In addition to scheduled "break-in" service, are you not doing an oil/filter change at winter lay-up?

Makes sense about the filters, just cracked me up about the differences...personally I am going to switch to the Purolator Pure one for my next change...

I just bought the boat in may 2009, it was a leftover (2008) on the dealership floor, so they threw in every option possible to get rid of it...dual batteries, swim platform, transom shower, bow filler cushion, 2+2 engine and O/D warranty, depth finder, blaa blaa blaa....all for under 20K :)

..... I changed the oil in the fall (late oct) with what i am guessing in the range of 25-30 hrs or so.....I forgot about the filters until I read another post here recently. I have subsequently added an hour meter over the winter to avoid future issues!

This is good! Keep a log book! It will be great for the day that you sell the boat also.

The reason for an oil change at lay-up time is to eliminate any alkalinity and/or acitity in the oil that remains in/around certain internal engine components during the lay-up duration.
Best to change both oil/filter and run engine afterwards!

Is there any way to find out what branded oil filter corresponds to the Mercury installed oil filter?
I hate to assume but can I buy a Fram/Purolator that filts the motor?

This is where I went to find the Purolator comparison.... I am not sure if an auto store would have it in their computer...I never tried...

my merc filter was 35-883702K and it came up with a L10111. I would imagine yours is a different size...

Of coarse, now you have me wondering about flow rates....

My local auto parts store stopped selling Purolator, said they were cheapened up to fit WalMart shelfs. They only sell Wix now. Something to think about.

Here's one of several filter comparisons. There's four pages to the test. http://home.mindspring.com/~cewhite3nc/index.html

Last time I bought Phram filters, the metal case was beer can thin. Almost crushed it when I pulled it out of the box. I'm not using them again.
