Did I pick the wrong oil filter or is something else wrong?

[Setec_Fl]

I used the K&N cross reference chart and selected an oil filter recommended for my 2008 AR210. The filter was replaced Labor Day weekend. I may have about 30 hours on the new filters. And yesterday, I got a low oil pressure warning light on starboard. Opened the hatch to see this mess! Did I buy the wrong filter? I was told the Yamaha OEM ones don’t have as good of flow. But I can’t imagine a marine grade filter rusting through in under a year.

help me pick a better filter please. And thank you in advance.

Did you dip it in the ocean before install. That is horrible. I would just stick with oem filters. Why would they be insufficient for their engines.
If an oem filter caused a problem on their engines i am sure they would redesign them.
I know there have been part number changes a few times on the oem filters for my boat and skis. So they either are updating the filter or using an other manufacturer.

thin film of grease on the filter?

Dang! Looks like saltwater took advantage of this one. I've used K&N before but mainly stick with Yamaha OEM ones. I've had K&N and the OEM develop rust, but nothing near this. I Spray a coat of YamaLube on them when I spray my engines.

 

[Setec_Fl]

Thanks. I’ll make sure to spray them down when I get the replacements installed. I’ve checked the engines while underway and don’t see water coming from anywhere. Not really sure how it got that rusted.
I’ll look for the OEM one and give that a try. I believe it is 5GH-13440-70-00. I honestly liked the KN because of the wrench off feature. But I’ll go with what ever doesn’t ruin my engines.

 

[ToddW850]

Yeah @Setec_Fl I liked the K&N for the same reason. But I have to say I haven't had issues getting the OEM off and on. So that's a good thing.

Have you checked your oil to make sure there is no water in it?

Have you checked your oil to make sure there is no water in it?

i did when I changed it. The rust seems all from the outside. I will check again when I get the new filters in.
Is there a site that tells you the correct OEM filter number? My owners manual says to refer to the service manual which I cannot find online.

Did you find that filter when you were snorkeling or what? Stick with OEM

I do not have TR-1 motors, but I believe this is the oil change kit for you boat:

I cannot fathom how that rusted THAT badly in a matter of months.

I know K&N has had issues in the past, and there have been knockoffs sold on Amazon that were garbage, but if that's a NIB from somewhere other than Amazon, I would contact K&N.

Doubt you still have the box, but they may have you send it in to see what's up, and replace it no cost. K&N are great filters, so if it matches up, it never should have performed like that. I have run them for years on my cars, through Wisconsin winters, and never had one look remotely like yours does. I suspect something other than the filter is the issue, unless that's a knockoff you received.

Is there a cut in your bilge hose or other line that is possibly spraying into the bilge? I just replaced a section of hose that had a small split in it so when the pump came on it would spray the compartment. I am only in fresh water so it wasn’t that big of a deal.

 

[Setec_Fl]

I am less concerned about a $15 filter and more worried that my motors are messed up. Both filters are rusted and these engines have been babied. I flush them for 10 mins every run with salty captain.
I will check the bilge pump hose next.

I have 15 seasons with KN303s each year. Not in saltwater, but that looks years old, not months. Yamaha filters are made by denso. You can search almost any filter and find that they are great or crap.
