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 534 Super Duty
Here is the result of a little more digging on my part, since this post peaked my interest in this old iron.


"In the late 1960s, OSCO purchased the SEAMASTER Marine Engine Co. and added to their existing product line a Seamaster "300" six cylinder gasoline engine, and two V8 gasoline models based on the 534 cu. In. Ford industrial engine. The most powerful Seamaster model boasted twin turbo chargers and inter-cooling way back in the early 1970s."



--------------------------


The following is an excerpt from the Seamaster brochure.

"In 1963, George Sarant of Freeport, NY saw the need for a large, dependable inboard gasoline engine that would stand up under the rigor and demands of offshore canyon fishing. As a Ford dealer, he began to marinize the heavy duty industrial 534 cubic inch Ford block, noted for its high torque at low rpm. It was rated at 277 HP @ 3400 RPM and was designed for demanding applications. From the beginning, the primary concern was to build a high quality marinized version of the 534. Some of the features were monel manifolds, fresh water cooling, top mounted accessories and starter as well as the factory designed mechanical overspeed governor. The engine has always been a custom built powerplant. It is still assembled by an individual mechanic with the care and attention to detail that characterized the first engines"....."A world renown sportsfisherman, Ralph Christiansen, owned a 41' Rybovich which was powered by twin SM 534's with over 10,000 hours of operation. As was related to Mr. Christiansen, John Rybovich stated that the boat was formerly captained by Walter Clay - a tough running captain who could not keep Chryslers in the boat. After the Seamasters were installed, try as he might, he could not hurt the engines".

Tough, easy to maintain engines that can offer up to 10,000 hours of service to the fisherman who wants to spend his/her time on the water not in the "yard".


----------------------------

Talk about durability, I'd hate to be the guy who tossed these motors out when they reached 3,000 hours.
