You may want to re-evaluate that statement. I'd say a sudden loss of oil pressure at high rpm due to a failed oil filter would be enough to harm your engine if not caught in time. Had it happen three times. In each case, the fault was the filter. Of every brand I've used, the only oil filters I've had fail were Frams. Giving them 3 chances over a two year period was enough for me to not recommend them anymore. That's a pretty high failure rate considering they weren't the main brand I was using at the time. Maybe they've changed but there's no way I want to risk anything I work on or own until the general concensus convinces me otherwise. For now, that's not the case, but don't take our word for it, there are many wright-ups on the internet of similar experiences.


Viper... think of what you're saying, and what my use of the filter is...

I'm not using it as an oil filter, remember?

I assume you're replacing one of the current filter assemblies and not adding an additional one or you may create a whole new problem.

I want to buy a proper fuel filter/water separator to replace the PH8A, but have not been able to find one with a 3/4-16 thread. You'd think it would be easy to search via the thread size of the filter, but not so much.

I realize that. My comment was directed at the statement that the quality of the filter can't hurt your motor, that's why I put it in quotes. Just putting it out there for the benefit of everyone else. In the case of an oil filter (and fuel filter in some apps), especially Fram, it could cause damage. For what you're doing in this thread, it's probably fine but MJK1040 and myself are just cautioning about Fram in general so others are aware.

Try someone like Summit Racing or similar. They may have or know of units that might work.

You type way faster than me ;-)

I understand that completely. I would never run a Fram PH8A as an oil filter. The guy that had the boat before me ran them, but I have Crusader factory filters (which I believe are made by Sierra) on it now.

I'm going to try calling Sierra directly. I have a part no for a Sierra filter without a drain, but a drain would make my life a lot easier. Their online cross reference guid is trash.

If you don't get anywhere with Summit Racing or Sierra, see what Racor has to offer for inboard gas. I like their units, they're an excellent filter/separator. You can drain them through the bottom housing without removing the element. The challenge will be the fitting size you're looking for.

Baldwin has a fuel filter separator that I have used, has a drain on the filter....not sure if it would work with your filter head though....mine fit an old Racor head......check em anyhow.
The above is strictly my opinion.

Wix has a spin on cartridge type that requires a bowl (WF10228):

As well as a cartridge type with a drain that doesn't require a bowl (WF10161):

https://www.oreillyauto.com/detail/b/wi ... 61/4837205

I'll get one of these two types next year, after my initial run of 2-3 hours. As it stands, I'm replacing these damn filters every 2-3 hours of run time. I'm not throwing out a $20 filter every boating outting. It's not the cost that bothers me, if it was necessary I'd do it, but the waste of it all grinds me. The Fram is doing what it needs to do at this point.
