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 !

      However...........I have not had real good success in getting mine to idle down that far. If they idle down too far the Parqons will shake and make a sound like the world is coming to an end. In my experience, running them a little faster is just easier on everything. I am not real sure just how fast mine are running, but I would think they are around 700, maybe even a little faster, which still makes it easy on shifting while docking. One thing you do not want, is to get them to idle down so far that when you shift into reverse at the docks you stall out. I always ease into a gear change anyway.

      Also, be advised that if you swap to a 4 blade prop, that WILL put more stress on your drivetrain when you shift, as those big 4 blades will grab a lot more water and transmit a lot more shock into the system. I likeed the 4 blades I purchased a few years ago because they gave an almost instant response, however, there is nothing wrong with a little more spin while docking and a little less bite. While I like the 4 blades while cruising, I think the 3 blades are a little easier on the equipment, as a side note to your initial question.

      Regards,

      Paul
