PCM 351W fresh water cooling (FWC)

I actually have new old stock R025002 the Y pipe. it is a NLA part.
And I have the thermostat housing that is NLA part also New.
I also have a complete 351 with fresh water on it for sale. not going to seperate it but if one wants a fresh water set up one can get a complete running engine package.[URL= https://panamacity.craigslist.org/bpo/d/panama-city-marine-ford-351-and/6857320127.html
i see you are in South Africa could be a stretch with any parts..

The expansion tank and heat exchanger will be available from other sources, but if PCM has them get them but the system will revolve around those first 3 parts.

Thanks Gary. I do have the full instruction manual, and upon paying closer attention I realised why they include the riser gaskets, pcv hose, etc. in the kit - as you explained. I also found the full PCM parts manual here, which is very helpful: https://www.marinepartsguys.com/product-tag/pcm-marine-engines/ .

I contacted PCM as you suggested. They referred me to Trans Pacific Distributors (www.transpacificdist.com or www.marinegate.com). These guys seem to have almost all of the parts in the FWC kit parts list available, except for what looks like a few generic pieces of hose. Not sure why PCM discontinued the conversion kit if all the components are still available. Be that as it may, I also enquired from Marine Parts Guys (www.marinepartsguys.com) about the six parts you mentioned in your first post, and they informed me that they are all available. So it looks like I'll get the parts I need from one of those two sources. Thanks again for the help!

Do you have the actual instructions or just the parts list? I obviously cannot speak for them but if you follow their instructions they want you to remove the risers from the manifolds to move the water inlets from the front to the back. You then need to change the gaskets. PCV valve hose needs to be longer and I suspect the valve it's self may be one with a 90 degree bend built in. Either way you would think they should be included but who knows....
If you need the instructions I have them but have no scanner,maybe I could take a picture of them and post if you need them.

Might check if crusader has something similar...

I have installed flushing connections, so I do flush after salt water trips, but my boat may sometimes be moored in salt water for e.g. a week or two in places where flushing on the water is difficult.

And yes, we did have some severe water restrictions in place, which made flushing a bit tricky, but our water situation is much better currently, so flushing is less of a problem from that point of view currently.

Wilhelm,
There are several companies that make generic fresh water cooling kits so check what's available in your area. I'm sure some fabrication of bracketry would be needed as well as some custom hose/plumbing work.

The alternate that many do here is add a means of flushing with fresh water after each outing. Is that possible as I have heard that there is a major water shortage in your area. Is the shortage still a concern?
