How to make a 1/2 through hole a 1 1/2 through hole?

I've been to chicken thus far to pull the log meter wheel out while still in the water for cleaning..Sort of like jumping out of a perfectly good airplane or something like that..

I just keep getting this sensation Murphy is sitting on my shoulder saying.."Go ahead do it I dare ya!" every time i have contemplated it...

This isn't too bad to do... especially if the knot meter housing has a flapper to close off the tube as the knot meter is pulled out. I don't have a problem with it, since I could sail with my knot meter out...and the two amas would keep the boat afloat. The cabin would be a bit soggy though.

The first time is the worst Still, after that it just scares the crap out of you

Seriously, it's not bad, a little water sprays around but not more than a towel can wipe up. The ones I've had did not have a flapper. No big deal really.

In pulling the knotlog transducer, you do get a column of water before you get the plug in; it's not too bad and the bilge pump has no difficulty handling it. I can't imagine a 1-1/2" hole and how fast that water will come in! I guess you would have to have every thing you would need for the job and not have anything go wrong! Now, when has that ever happened?

Works real easy!

Bloody brilliant!
