This Atomic 4 was brought to DYS for a rebuild after a delivery skipper ran it to hard. The engine and reduction gear drive train were completely torn down by DYS, and re-manufactured, then bench tested. The Video shows it running on the test wagon.
This Atomic 4 Reduction Gear Engine was rebuilt by DYS  after the engine froze, because of salt water getting inside. The middle two pistons were both stuck to the cylinder  walls, and had to be forcibly removed from the block,and  replaced.  The entire engine and drive units were rebuilt. This video shows the engine before & during the  test run.
This used Atomic 4 was re-manufactured by DYS to replace the engine in a Tartan 30 sailboat. DYS removed the old Tartan’s engine, and installed this one in its place. The Video shows it prior to startup, with some suggestions for owners, and while running.
This engine came to DYS when the owner said it was running roughly. Upon testing, it was discovered there was no # 2 piston. It had come loose from the crankshaft, and been destroyed by the running engine. DYS completely dis-assembled the engine and rebuilt it with all 4 pistons. The video shows the engine’s test run, prior to installation.
