"Torpedo Tube," Precision 23
Trailer Engine Mount, Precision 23
The "torpedo tube" is the home of Pflotsam's mast raising pole (described on the Precision Owner's FAQ page). The tube is constructed from 4" PVC pipe with a threaded "clean out" fitting on each end. Also visible in this picture is the support for the lower unit of the engine and 2 of the centering guides added to simplify retrieval.
