OK, now I am really worried. I was initially surprised when I saw the gasket.
And it was remarkably secure. before freeing up, i did put my weight on it from the inside and it didn't budge.
And I thought the old through-hull looked pretty good. I didn't see the gouges in the flange until you pointed them out in the picture. They are not as obvious looking at it as it is in the picture.
Gasket is rubber-ish. Its looks like the standard gasket that came with the transducer but meant for the inside under the lock ring.
So I guess my options are:
1) find a new throughhull that matches my existing transducer (Maine Sail.. could you point me to a sorce for this?)
2) get an entire new transducer including new throughull
3) put in a new throughout with sea-cock just to close off the hole... and no transducer
4) permanently close the hole and not have a knot transducer.
I'm still not clear on how / what to modify the hole?
Are you saying the entire flange need to sit flush on the surface of the hull to seal properly?
That certainly was not the case with the old one. And where its located. And based on where its located That would be difficult to do with the concave curvature of the hull at that point.
While not my preference, I can certainly live with out a knot-meter since mostly rely on GPS speed anyways. (Yet I know its not the same thing!) Does autopilot (EV 100) use knot speed when sailing be the wind?
I'm getting a quote from my yard now for the options. Leaning between options 2 & 4 as fastest, cheapest and safest solution.
So much for the easy, cheap do it yourself maint. And I thought I launch early this year :-( Grrrrrrr
