This Atomic 4 came to DYS - rebuilt by a private party, but not runnable. It was completely torn down by DYS, and re-manufactured, then bench tested and installed. The Video shows it in the test wagon when complete, and running ~~ prior to installation.
This Atomic 4 came to DYS in barely running condition, for a full rebuild. The block, transmission, and V Drive were dis-assembled, cleaned, painted, and re-manufactured. The Video shows the completed engine on the bench, while test running it, prior to delivering it to the owner.
This Atomic 4 was re-manufactured 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 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. This video shows the rebuilt engine before & during test run.
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 and been destroyed by the engine. DYS completely dis-assembled the engine and rebuilt it with all 4 pistons. The video shows the test run, prior to installation
