CHRIS CRAFT COMMANDER FORUM ® .......A photo-intensive technical reference file and ongoing newsletter regarding the original fiberglass Chris-Craft Commander series. This is an independent not-for-profit and non-commercial web site, not affiliated with the Chris Craft Commander Club ~~ or ~~ Chris-Craft Corporation. Our mission here is to "have fun and share information" about the Commander series (and those associated fiberglass boats on the Chris-Craft family tree) for your individual personal use, and by doing so help promote the good name of Chris-Craft, and help preserve, restore, and appreciate Chris-Craft boats. The main reference feature is the ever expanding MASTER INDEX File which contains what we believe to be the world's largest collection of documentation photos and technical information on the Chris-Craft Commander line of boats, (like these original brochure scans, featuring the iconic first 38 Commander styled by Fred Hudson, and many of the great Dick Avery renditions that followed) , (a huge collection of Chris-Craft 427 tuning and specification information), and a few words about how to use the forum.

We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".

Closed cooling

Response to I don't know the answer to your question, but it should not be difficult to install

Paul and Pierre:

for some reason Network54 forgot me so I am now in under a new name.

I already posted a while ago about my 1968 Lancer w/IO repower project and intend to use closed cooling for the engine. I have gotten a lot of conflicting information/advice about the possible perils of doing a full closed cooling system and at this time am inclined to go block only.
I see a number of different vendors who make after market closed cooling kits and wondering if anyone has any opinions on sources good, bad or indifferent.

One thing I know for sure is I will be using a crank driven raw water pump and pulling raw water thru a hull fitting, not the Volvo I/O unit so I am sure I am moving enough water.
Since P/O had already installed two 3" exhaust outlets thru the transom I will be using them for exhaust, not the i/o unit. I do need to find or fabricate a plate to block the exhaust opening in the transom shield.

My previous thread ended with me fighting with the old PDS unit and retaining ring and fortunately I have been able to find a brand new replacement, that has quite the adventure.

Currently too cold for any serious work here in RI but will post more updates soon.
