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 !

      During my visit we pulled out the propeller that came with the boat and it was a 3474RH which upon getting back home to my database appears to be a 14 x 14 RH on a 1-1/4 shaft. This one was Nibral and had a slight cup. Based on the prop, there is no way the Paragon v-drive is anything other than direct drive, so just for grins I did a calculation using a 15% slippage/drag number and with this prop the boat should be in the 45+ miles per hour range at 4000 rpm engine speed. That is actually pretty darn fast to be hurling a 23 hull around. The engine, by the way, is at the shop getting the full treatment, including new pistons and camshaft sourced trough George Anderson at Guessford Machine.

      Ill post some more photos tomorrow when I can get to a better internet connection, out there in the hinterlands our cell phone and satellite connections are just a bit on the slow side sometimes.

      That 427 oil cooler in the previous photos, by the way, looks identical to the one I got (also from Robert Henkel) happy.gif

      Best,

      Paul
