FWC and rebuilt engine install advice sought.

[dougslug42]

I am currently in the process of installing a freshly overhauled A4 and have a FWC heat exchanger with all the hardware. My request is, does someone have a diagram for plumbing?(Ill try and get a brand and photo) I understand the fundamentals of said system, but dont want to make a setup up mistake. My boat is a small 14 foot launch and you could say I have a "blank canvas" in regards to installation and setup.
In addition, I am also putting in new wiring but trying to use the original electrical switches, instruments and gauges .
Lastly, I must say I really enjoy this forum and gather a lot of good intel for this classic engine.
Thanks in advance and have a great day!

Hello Doug.

You may already have this, but in case you don't, here are the MMI instructions for installing the Moyer FWC system, with diagrams:

Hope this helps.

Welcome to the forum.

It your FWC system based on a mechanical pump or electric?

[dougslug42]

Yes it is a mechanical setup. It indeed seems to be a MMI fresh water cooling system.(but there seems to be no markings) I will go through the parts tomorrow and take inventory. Thank you for the link, it is most helpful.

Big question - does it have the heat exchanger you see in the Moyer listing or the one some A4s come with that mount on the engine?
