Got myself into a bit of a pickle.Started the boat after assembling the motor after winter shut down.Good oil pressure,water flow,temp,voltage etc.after about20 min shut motor down to change oil and filter.Drained oil,put wrench on oil filter ,would not move.Filter started to twist and leak but not turning off.Pounded screw driver through filter and tried turning.No luck,now i'm basicly down to the top of the filter only where when I reach under I can feel the inner filter thread and the 7 holes on the top of the filter.I'm not sure if it's the rubber ring or the thread holding it on.All the body is off the filter,twisted and bent.How can I remove the remaining part of the filter so I can install the new filter(Qs30).thanks homerl.:confused:
 
The filter is always hand tight,as I change it once a year.This is the first time this has happened to me,as I change my own vehicles oil changes.What if I reach up under and try lightly prying it off,as the housing is somewhat accessible but by feel only.That would be a shame to pull the motor for that reason only I would think?Any other options?
 
Did you oil the rubber gasket on the filter before installing?
Also... instructions don't say "hand tight", they usually say 1/4 or 1/2 turn after gasket contacts base.
Try tapping one of the seven holes ( use some kind of pin or rod and a hammer) to turn the filter.

Yes I did, I oil'd it and did it hand tight+
Thanks for the options

I was thinking a wrench with 2 pins welded to a bar, and use 2 of the 7 holes and try to turn it off that way. What do you think?
 
get a set of water pump pliers and stick the handle ends in the holes and use a screw driver between the handles and twist it off.

Been there.............................sucks to be U.
 
any long handled pliers that have handles small enough in diameter to fit in the holes is all you need
 
Guys thanks for all the options,but I ended up using a grinder disc wrench for a four and a half" grinder.Two of three holes fit with one hole left in the middle.Bit of a tug and off it came.I don't know why that happened but I again oiled the ring and put it in hand tight and a bit (no wrench).Thanks again for all your help guys,I'm sure I will need help in the near future.homerl
 
Any chance there was some crap left on the filter mount from a previous filter?
Was the filter a different brand from others you've used?
You might want to consider a remote oil filter kit so if this ever happens again, you can take the whole thing off and work on it in comfort at a bench.
 
Sandkicker,it is the same Qs30 filter I've used for over three years(I change at least one time per season).Did not feel anything on the threaded shaft,and full gasket did come off.I think at this time I will treat this as a one time only problem, and if it happens again I might take your advice of a remote filter.Again thanks for the option as I did not no about the remote filter setup.
 
You may want to consider putting on a remote filter kit.....it will make the routine maintenance easier in the long run.
 
chit happens, one time deal maybe. I also would stick with the brand of filter if they have been good for years. Got a bad one last time, could have happened.

If it happens again then i would change filter brand if it were me.

By the way i use fram, i know, i know, some don't like them, i use them on all the chit i own, 6 cars, my friend has 6 cars, and a guy we know owns a big company has i don't know how many trucks , we all sorta help each other out.

We all buy them at wally world oil also.
 
When I purchased my boat, my v8 is way down in the boat and getting to the oil filter was a stand on your head situation.

I went to nappa and purchased a remote oil filter adapter for the block and a remote mount for the filter and they made the hoses for me to length that I specified.

I made my own mounting bracket and mounted it to the exhaust elbow like the factory does it on mags and big blocks.

It was about 30% cheaper in price and it added about 1/3 qrt of oil to the normal amount needed.

I still only use 5 qrts when changing oil.

This makes it very easy to change the oil filter.

This suggestion is a very good one and if reacing the oil filter is difficult it is the only way to go..............
 
I was told Qs were good filters for marine engines,use to use fram,but only changed because of feedback on this forum some time ago.With the dog house off it isn't that hard to change,if all goes the way it's suppose to.I will indeed look into the remote filter idea anyways.Again thank-you everyone for your help and ideas. homerl:D;)
 
I can't hardly say anything here without piling on top of the downed hurdle, and further injuring one of the players.
But....... (I hate those Buts)..... it is so important to fully warm an engine up prior to removing an oil filter. It just isn't worth an attempt unless you can see the filter rotate some before going further.
And by all means, use the correct tool..... and a good tool, ONLY!

I've always done this, and as a result, have never (in forty some years or more), had to go through this.
I have removed several that others have gotten stuck..... and it is no fun!

Even if you end up having to break part of the filter, and even damage the filter base fitting, these are available as a replacement.

I fully agree with kghost and makomark on the remote filter idea.
It too can be a PITA to install, but it's a one time event!
I would try to avoid the inverted cartridge style remote base, and go with a base that places the cartridge in a conventional fashion, IMO.


Good luck..... I do hope you get it!

My MERC has the remote filter mounted upfront and proud.... and upside down ( open end down). After some thinking about the mess this was going to make, I just unbolted the adapter base mount from the engine, tipped it over a tin pie plate and removed the filter. BTW... I "broke" it loose before I removed the bracket to make it easy to remove the filter... OK.. I lied, I wasn't that smart the first time :)
