Good & Bad

Passage Maker - - The Right Stuff - BY STEVE ZIM­MER­MAN

The in­line valves on this boat ( top right in the photo) suf­fer from mis­matched and poorly cho­sen al­loys. In ad­di­tion, us­ing the thru- hull nut at the bot­tom does not pro­vide ad­e­quate sup­port. Just to the left, a new proper sea­cock is be­ing in­stalled. The wide flange base pro­vides ex­cel­lent sup­port, and the fiber­glass pad be­neath it re­in­forces the hull and makes it pos­si­ble to screw the base into the back­ing pad. In the process of in­stalling the new fit­tings, the hose that pro­vides sea­wa­ter to the shaft seal flexed and the con­nect­ing nip­ple snapped off. The pink color in­di­cates de­com­po­si­tion of a brass fit­ting. If you look closely you can see that the open­ing it­self has be­come blocked, re­strict­ing the flow of wa­ter needed to cool and lu­bri­cate the bear­ing. Good preven­ta­tive main­te­nance calls for re­mov­ing this hose an­nu­ally to check the con­di­tion of the pipe fit­ting and to con­firm a healthy flow of wa­ter with the en­gine run­ning.

We’ll award the new sea­cock in­stal­la­tion The Right Stuff stamp of ap­proval. As for the rest, well, let’s just say it pays to do it right the first time.
