Optimax oil filter?

I have a 2008 115hp Optimax that I love dearly and maintain religiously. But the owner manual
says there’s an oil filter that must be changed yearly by an authorized service technician. I admit
I haven’t been able to find where that is and I haven’t had that filter serviced since I do all my own
winterizing and changing of filters, plugs, etc.
Does anyone know where that oil filter is located, and if it’s truly something I shouldn’t be
replacing myself? That’s the only maintanence item they clearly specify must be done by a
factory tech so I tend to believe I shouldn’t do it.

Interesting. Are you sure it’s an oil filter and not a fuel filter? Since its a oil injection I’ve never seen an Optimax utilizing an oil filter but I could be wrong. I did change the fuel filter on my 250 Pro XS this year and it was simple with the right wrench to remove it. If its truly an oil filter i would imagine its an inline oil filter and this might be cheap insurance to have a tech change it since its most likely located between the engine oil tank and the injection pump and can cause problems if not done properly.

Ya sure its not the water-fuel separation filter?

I can’t say for merc for sure, but my Johnson, apparently had an oil filter in/on the oil res. I suspect on the pickup or something.

I did a little digging and I’m guessing the answer is “Depends”. Probably by year of motor.

In this link, the schematic shows a filter screen in the oil pick up tube. (#2)

In this link, scroll all the way to the bottom of the page and read the post from bluewaterpilot. He talks about an in-line filter. (with pics)

I looked at my 2003 150 Opti and did not find any in-line filter. I had the screen in the oil tank that checked out clean last night.

Good Luck,

Yep, I’m sure it says oil filter. But I can’t figure where it is. I guess
maybe that’s why they say to have an authorized tech replace it.
