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 !

Response to 427 tune-up diagnosis help

Greetings all. My last weekend at the boat brought some promising progress. Since the fuel in the tanks is suspected to be the root of my problems, I have been tuning the engines out of a jug in the cockpit. Sunday, both motors ran at the same time for the first time in months!!! This came after confirmation that the compression on the port side is in good shape (ranges from 160 to 175 on all 8).

In a previous post, I noted that the idle screws had little effect on the motor, even at idle. I ran out of time to try them after valves were checked and adjusted and compression was confirmed. I still haven't confirmed the vacuum, but do have access to a guage. I will try this if the condition persists.

The end result is that the port engine sounds beautiful. When I bought the boat, it would lay a film on the water. Now there is nothing. No smoke and no smell. The water flows out in volume without rythm or pulse.

By contrast, the starboard has a clear beat. The water flows out of the base of the pipe, but also splatters out around the edges from 9:00 to 3:00 with the beat of the motor. This motor now has all of the parts applied to the port: wires, plugs, coil, edelbrock carb, fuel pump, blood, sweat, tears... I'll be confirming compression, valves, timing (again). Based on all indications, the motors will be starting at the touch of a switch before long.

This brings me back to the root of my troubles, bad gas. This boat has been around the marina for a while. By most accounts, it hasn't gone more than a few miles in 7-10 years. I have tried a few products in the fuel, and tried to chase it away with more fresh gas. It took 50 gallons in each tank to top them off. Now, I am sure that the old gas must go. My problem is finding where to take it, or who can take it away. Does anyone know of a good resource/reference for finding this type of service?
