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".

potential air pocket issue at the upper end of the motor

Response to Thanks Guys.......good research going on here !! (Cooling diagrams attached)

Comments contributed by the Chris Craft Antique Boat Club guys suggested there could be an air pocket formed by placing the thermostat to the lower side of the motor and upon looking at diagrams and side sections I agree this could be an issue. There were suggestions about tapping the front sides of the heads (like the early flywheel forward 283) or perhaps tapping the top side of the new aftermarket intake to sneak a passage into the head on the topside of the motor with intentions of using that as a safety measure to take out any air bubble that may form.

Very good thoughts, and I did get in contact with Kris, who has done this conversion and run his boat successfully, who said he would be posting photos soon so everyone please stay tuned, we'll continue on this collaboration and come up with a viable solution for sure.

regards,

Paul
