ZEROING A CPP

The Coast Guard has been operating cutters using controllable pitch propellers since the mid-sixties. Over these years many engineers and operators have been frustrated and, in some cases, annoyed because the cutter creeps forward or aft, with all built-in indicators indicating zero pitch. This has occurred even after precise alignment of the system during drydocking, or by using the services of divers to check match marks on the blades/hub. This ariticle will attempt to explain what is happening and suggest a procedure to be used that will make everyone (well, almost) happy.
