Crack in keel by rudder

Post by chris.nackers » Tue Nov 10, 2020 9:34 am

Hello all,

I will try to grab a picture once i can get a good shot. But going through a few things, i noticed that i have a small crack in the keel on the very end by the where the rudder mounts. It doesn't leak, and best i can tell it's not all the way through.

So question is, is there a way to repair that? If it would require replacement of the entire keel, that would be a massive project as the bottom is 5200. I'm going to guess you can't just pop the keel out without removing/redoing the bottom?

Thanks in advance for any advice!

Well as you mentioned, pictures will help us in offering ideas but until then...

Yeah, the keel on a Sportsman will not easily "pop" out, a major task to say the least. Probably a simple repair depending on the cause of the crack. There is stress on the keel in this area from the rudder turning the boat underway and the grain may have just opened up a bit, assuming there wasn't damage from striking an underwater object. The real cause needs to be investigated as yes, rot can happen here weakening the keel. Sounding with a small pick tapped in and around the area would reveal punky wood if it exists. Even if the keel has some local rot, a new section can be scarfed into the existing sound keel if needed. Might only be a more cosmetic fix such as using a filler or routing the crack to accept a glued in spline.

For sure, will get a picture tonight hopefully. Will be in the garage to pull the engine. Lots of stress on that point, so not shocked.

It appears to be right with the grain, I'll poke it a bit and see if it seems soft.

Alright here are a few photos, hope this helps. I scraped some of the paint away to try and show it better, i'm repainting the bottom anyway this winter.

I like the route it out and glue in a spline idea....there is such fantastic good out there...way stronger than what that requires.
