This video is for the test run of an Atomic 4 rebuilt by David's Yacht Service of Southern California. Another party tried to put the engine together without gaskets using mastic instead. The owner brought it to DYS who took it apart and cleaned all the mastic off, then rebuilt it with gaskets. The finished product was also painted and both looks and runs great!
