I have twin Fisher Pierce Bearcat 55s that came on a recent boat purchase and need to get them mechanically sound. Weather I keep them or not.

I've beaten the internet and talked directly to Globe on the impeller (part # 223) and they seem to no longer be in existence. Looks like the same impeller was used in Scott and McCulloch.

The oil filters where actually also used for fuel oil furnaces. Napa #4104 Wix #24104. I used a cross reference chart and found many other brands but so far all dead ends.

Thanks. I called them and the guys have a ton of info but no parts any longer. Seems to be a running theme. AOMCI web site wasn't working yesterday. Wouldn't let me sign in as guest.
It is a scott 3 cylinder lower unit, If it is the same impeller those are being made yet by people. Join the AOMCI and you will find somebody there to help you.

I chased Baldwin filters. The link you mentioned is Australian. I'm in the USA. Went pretty far down the road with petroil.mx. Over a two week period they said they could get them, had them double check, still all good till the processed payment then found out that they couldn't get them.

John from Zemp did call me today and he is still modifying impellers to fit. Have two coming. He said filters a thermostats were no longer and only option is to run without.

Also called robertsmaritimesystems.com and got lots of back but he has no parts

since 24104 lists for home heating oil as well... I'd chance and buy one of these https://www.amazon.com/General-2605...ords=furnace+oil+filter&qid=1642019569&sr=8-8 The filtration specs match up and the threads do as well. It should work. These I think were adapted from the get go as Crosley used a canister filter ( CH11RP, long gone ). Earlier Crosleys used a bypass system for filtration ( or no filter at all ) but I don't really know too much... You could add a bypass system really easy but it might not fit under the hood

The one you listed if the picture is accurate has the wrong Inlet holes. The one that goes on the motor only has the whole that's threaded and none of the multiple holes around that. Unless somebody could come up with an adapter of some type

Make an adapter to fit a popular filter on there.-----There are so many good small filters to pick from.

Your right. I looked at it. Not right. I think that is the filter that is unobtainable that the Crosley boards are referencing as NLA. CH11RP

However, I think you have an oil filter adapter just like the Crosleys, and if so. Service Motors sells modified adapters. https://www.servicemotors.net/?product_cat=&s=oil&post_type=product

Somebody that would build an adapter to take a bypass common filter would be whipped if you could still make everything fit happy under the hood.

I called the guys at service Motors that you linked, and they didn't have anything to fit the what he called "high performance motor"

Those are the high performance version of that motor. A lot of people pulled the powerheads off of those and put them in the cars. Just because they were more powerful.

When the snow level drops I'll have to pull one of my existing filters and see what we have there now and do a little brain storming. This may be the ticket. I hate to run without a filter especially on an old engine.
