Yammie Oil Change/Filter Change

[guest]

Stupid question but here goes - winter caught up with me quicker than usual this year, so I did not change the oil filter in my Yamaha 150 4 Stroke when I changed the oil during my normal winterization process. I live in a rural area and did not have a filter on hand, yet I wanted to get all of the other winterization things done before this weather got any colder/worse. My question is - can I change out the filter with a crankcase full of fresh oil? I'm borderline on needing a new filter (specs call for 100 hours), so if it will be a really big mess, or if I can't do it, I might opt to wait til mid season next year, and just do a complete oil change including filter? Comments appreciated.

I "think" you would be OK as long as you change the filter before you start it again in spring. If you run the engine, the clean oil will run through the dirty filter and contaminate it. Depending on how you changed it, I believe that most of the oil should have drained back from the filter before you changed the oil in the sump. If you changed the sump oil immediately after running the engine, there is a possibility the dirty oil from the filter may have drained back into the crankcase and dirtied the new oil. Just a couple of things to think about.

unless you run the motor with the new oil in it all its doing is sitting in the sump. it needs to circulate though the motor and get to the bearings etc to do any good.

if thats what you are talking about, kind of hard to tell from your question

Yes, you can change the filter even though you already did the oil. No problems.

P.S...I would change the filter now rather than waiting till "100 hrs". Every fall before putting the boat away it's a good idea to change the oil, lower unit, oil filter and water/fuel seperator...especially in colder climates, regardless of hours.

The manual actually says every 100 hours "or 6 months". I feel that unless you're running your motor over 200 hours a year you should be changing it every six months, or sooner.

The book does say that under adverse conditions you should change more often. With the condition of the oil I changed at the last two six month intervals, there is no way I'm letting it go to 100 hours. I may be throwing my money away but I change oil when it get black.

Another thing I just noticed in the service manual is it also indicates that the filter should be done by a yamaha dealer. I wonder whats up with that? Could that be why a $6 oil filter cost up to $32.00 over the counter?

I wouldn't think yamaha would do such a thing but it could give them a loophole to bail on warranty repair if they knew an owner was doing his own filter changes, or using cheaper alternatives :huh:

What is it they say; A dollar saved is a dollar earned. So preventive maintenance is like financial planning. :bigsmile:

I did a oil filter change after changing the oil with no problem, just be sure to level the engine first (use a small construction level placed on the cavitation plate) As for the $32 oil filter, I have been using a wix filter($6) at the auto parts store. Yamaha tech support says this is OK.

That's what I normally do in terms of winterizing - ie, everything went522 stated, regardless of hours of use. I just didn't have a chance to purhcase a filter ahead of time. This fall cold, snow and ice caught me off guard and part of my routine is running the engine with muffs in the driveway. Looking at the forecast, I went ahead with my normal routine last week-end except for the oil filter (ahead of 5 F weather that arrived mid week). I just wasn't sure if I could change out the filter with a full crank case without causing a major oil spill. I appreciate the help.

Ok, teach me something; why level? I've been tilting the motor up and using a plastic bag over the filter to save some mess.

Oh no, could it be that when level the filter doesn't drain. Please tell me its so :blush:

What is the Wix filter # for the F-150 4-strock?

[MPW]

I have never tried to change the oil filter with the engine tilted up, but with the engine sitting level and a shop rag stuffed under the filter there is no mess. The Wix filter # 51348.

No one should be paying $32 even for a Yamaha filter. They should cost about $12. If you do not have a Yamaha boat dealership close,try a Yamaha motorcycle shop. They carry them.

Yamaha Website shows the construction of the filter compared to the automotive substitute in the following document:
