DYS Atomic 4 Repower History!

DYS acquired a 28’ Newport sailboat about 15 years ago. Its Atomic 4 engine was frozen, and it was replaced by DYS with a rebuilt engine, and sold. After several changes in ownership, and 15 years of service, the current owners brought the engine back to DYS for another rebuild, based on the prior owner’s good comments in the captain’s log.

Repower Project - San Pedro 30’ Custom!

A leaking exhaust manifold resulted in engine failure. The owner contracted DYS to assist with removal of the engine, re-manufacture another Atomic 4 block, and completion of the engine with all the necessary parts to replace his engine. Colors selected are a striking Orange & Navy pairing. Engine as installed.

Repower Project - Long Beach Tartan 30!

DYS was contracted by the owner of a Tartan 30 in Long Beach to provide him a re-manufactured Atomic 4 sailboat engine. His old engine was removed and the re- manufactured engine installed by DYS. Maui Blue and Sand, colors of the South Pacific, were selected. Engine shown as installed.

Repower Project - Long Beach Ericson 29

This engine was removed by DYS after being submerged due to a partial sinking. It is a newer block (1982), and was previously in excellent condition. DYS is doing a complete teardown, and replacing all parts that did not survive the salt water.

Repower Project - Long Beach CAT 30!

This beautiful engine came to DYS, after it ate a piston and connecting rod. The engine had been recently rebuilt by others, so it was dis-assembled and replacement parts + some new parts were installed, and then re-assembled and test run.
