So here I was floating in the California delta
, and I decided to check my prop zinc. I have one of those cone zincs that go on the end of the prop shaft.
So I dove and looked / felt and what do you know, No zinc. To make matters worst no screw that holds the zinc on either.
Now I hate not being able to do all the boat chores, and paying a diver to change the zinc is, well, I'd rather find a way to do it myself. After a few dives I learned that this girl does not work well underwater, that whole lack of air thingy really gets to me.
So being an engineer
and blonde, I started thinking out of the box again. So not a good thing sometimes.
On my boat I have a really large sea strainer. Well Large for my dinky little diesel
. Something like 1-1/2” size which is 4” in diameter and 12” high in brass and glass construction. Its connected to the seacock with a 2” diameter copper standpipe, which places the top close the the water
So I take the cover off, and pull the basket out. Wow, the Size C prop cone zinc easily fits within the basket strainer and leaves room all around. Nice So I drilled out the zinc shaft hole to match the 1/4” copper rod the holds the cover of the strainer down. I slid the zinc inside the basket, and its a really tight friction fit on the brass rod. Cool.
Then I got some #12 wire out and a few terminal ends to fit the ¼" rod. I attach the wire to the rod between the cap and wing nut and attach the other end to the aft engine
mount. Just to make sure, I measure continuity between the prop shaft and wire at the engine
mount and at the copper standpipe. Neet... zero ohms. We have continuity..Life is good.
Oh I'll probably upsize the wire to the strainer, but it will be a week or so before I hit a dock
/ location where I can get some.
As we all know, its rather important that the zinc be electrically connected to the prop shaft. Normally the zinc is mechanically connected on the prop shaft, but that's way too messy for this girl anyway.. Plus the cone zincs have a nasty habit of falling off, when the mount hole gets bigger from zinc loss. So annoying.
I'm thinking that based on the engineering text I read that the blonde zinc replacement might just work fine. The zinc is located inside the basket strainer so any little bits of zinc that break off will be trapped in the basket
So now I have an easy way, in theory anyway to check and replace my prop zinc without getting wet. I'm going to check it over the next few weeks to make sure its hum sacrificing itself.
Now I know there will be a few guys here who will say this will not work. Its Cruisers Forum after all. But I'm just going to give it a try and see what happens. The engineer
in me says this will work and the blonde says hey, hair and makeup are good to go. Sort of a blonde win win...
