Mercury Four stroke oil filters replacements

[Bishoptf]

I'm sure its just me and will be bending over for this oil change since the motor is still under warranty but my goodness prices for the oil filters is just absurd. I am running a Mercury Proxs 200 V8 four stroke, a pretty common outboard. The filters that are listed to support are Mercury 35-8m0123025 and Quicksilver 35-8m0176312. Last year I bought the Quicksilver for about $14 but this year they are around $18 and the Mercury filter is $20. I was trying to find a site that I can cross reference automotive filters, anyone know of a site?

Just thought I would see if anyone had any information, thanks.

Looks like Mercury also references the part number as 8M0123025 - see here.

Also, this is all I could dig up with Mr. Roboto, take it as research only - LINK.

What do the marine chat boards say as I'm sure you're not the first to try and find an automotive filter substitute for an over priced oil filter.

BTW - I highly doubt there is anything special about the Mercury oil filter except maybe the bypass valve setting. If you can find out what that bypass setting is then it might be easier to find an automotive filter cross-over, which looks to be the Fram 7317 and Purolator 14610 type of filters. You can actually determine what it is with a few measurements if you have an old used Mercury filter laying around.

From the previous link I gave, it looks like it's built by Champion Labs based on what's printed on the dome. Champion Labs is out of business as of lately due to parent company First Brands bankruptcy.

Yeah ive not found much if any forums discussing it, some older bitog threads but nothing about this specific filter. Most just pay the added cost and move on. I will be swapping the filter out this weekend and will see what is listed on the filter. Just think its silly when your swapping them every year or at 100 hours, not sure its going to make any difference. Dont get me started on the *cough* special oil called out....

You won't find anything useful on the filter. It will most likely have the Champion Labs print on the dome.

You should cut it open to see what it looks like. You could also make a couple of measurements on the bypass valve to calculate when it starts to crack open if you have some kind of scale to measure the force to crack it open and the diameter of the bypass valve opening.

The Marisol Marine link mentioned above crosses the Mercury part numbers to a Sierra 18-8703, which in turn apparently crosses to a Luber-Finer LFP8703, which in turn apparently crosses to quite a few common automotive sizes, like the Baldwin B7118 and others. YMMV of course.

 

[ZeeOSix]

Research results of automotive filter cross-overs for the Sierra 18-8703. Most likely based on physical size and thread pitch.

I use the Sierra 18-8703. Purchased from Orielly Auto Parts.

^^^ From O'Reilly's website. More reasonable price.

Being a fellow outboard owner, I understand the OP and prices. When they say "Boat" the price of everything goes up.
But you know BOAT stands for Bet on Another Thousand.

Outboard motors are expensive so I don't scrimp on maintenance. I just by, in my case, the Yamaha parts and fluids.

Yeah I always thought it was Break Out Another Thousand...but had a boat in some form or fashion for along time just think swapping synthetic oil when you have 50-75 hours yearly is kind of lame but thats just my opinion. I do the gmaintenance just seems they are still doing everything based on dino oils etc...year three they are wanting the water pump replaced...

Just think $20 for a filter is just obscene...but is what it is, will look at the sierra marine filter and alternatives.

For years I ran Fram XG7317 on 2 different Mercury outboards. I now have the same filter on a 2024 Yamaha 70 4 stroke outboard. Now that Fram is gone, will try to go with Carquest Premium on the next service.

For your $20K outboard that’s still under warranty may be best to use a Mercury oil filter…

Yup thats the plan, but next year no longer under warranty will probably use something else...not using Mercury oil this year though, Valvoline synthetic is NMMA approved oil. Takes about 6qt when filling, even Valvoline is more expensive than I would like. Wish there was a Supertech NMMA four stroke oil but have found anything cheaper than the valvoline yet.

$14 for Quicksilver 35-877769Q01 on Amazon. I have twin Verado 300s. $30 is a drop in the bucket compared to other operating costs. I can't wait to see this summers fuel bill!

Yeah for my filter its almost $19, last year I was able to pick one up for 14 but not this year. I wish i had had more options when rigging my bass boat but mercs were the only option. Not a bad engine but the v8 vs the HO of the v6 options would be much easier on fuel, I can't imagine feeding twin 300's, out of my price league, lol.

I've been running various Purolator 14610 filters on my 1999 Yamaha F100 tiller, for at least a decade. Not so much for cost, but convenience. I haven't had any issues.
