I'm trying epoxy with a touch of silica and a handful of chopped glass strands mixed in since I had it on hand. Just poured it tonight so I will see how it turns out tomorrow. If that doesn't work out well I can get some 2 part mold plastic from the same company that got the silicone from. I'll post a picture with the finished result.

Here are the finished emblems. I made the first one with epoxy and it turned out ok but I over poured it and had to do a lot of trimming. Ended up pouring a few more out of poly so I can gelcoat them if I decide to later on. I'm pretty happy with them overall.

Looks good - make a few more and stash them because they break easily. I made a couple for my 170 and the bait bucket (I don't have a baitwell) banging up against it as we idled along, broke it.

Good idea. I'll cast up a few more while I have it all out still.

Those came out great. I have seen replacements for sale once or twice before but it is much cooler to see this recreated using the original from your own boat.

Thanks Chris. I'm glad I was able to get a decent copy.

Got a little more done between the rain.

Mulch removed from the center stringer.



Refoamed with some leftover 4lb



And laid a strip of 1700 over the stringer tops, an extra layer over the tabs, and the chines.





I am also going to try the fence post trick to raise the stringer tops. Ripped two 5 inch posts in half for the sole and got 4 inch posts for the casting deck so it's got a little more of a step up.

Looking great man, stringers are next for me.  What is the fence post trick? Is them as forms to put glass on top off?

Thanks Marcel. Yeah, that's the idea. You glass them down to the stringer tops which raises the deck a little while giving you somewhere to run wires, etc without having to glass in a separate chase tube.

I ended up with a lot of bubbles in the center stringer. I've heard people say that glass doesn't like to go around bends very well and now I know what they mean. It seemed wrapped well when I left it but it pulled away in a few spots while it dried. I don't want any issues with water getting in there so I ended up cutting the top off again and filled all the voids up with resin. Lesson learned.

Also started to look at the transom tonight. Made a few exploratory cuts and pried back a few places. The sides have a good deal of rot but a lot of it is still pretty solid. I see a lot more grinding and chipping in my future...

This is the bend of the fence post you're talking about?  Maybe they needed to be roughed up really good?

No, it was the center stringer. I wasn't planning to add pvc there, I just wanted to keep the water out of it so I filled it with foam and wrapped a 6in piece of 1700 around it.

 I am holding off on glassing the pvc down on the main stringers until I finish the transom so I can run it all the way back. In hindsight I should have done the transom first but it is nice to be able to climb in and out of the boat without a stepladder for now.

You may want to get some 12 oz biax tape.  It’s available as cloth too.  Conforms much better around outside radius.

Thanks, I'll pick some of that up the next time I'm at FGCI.
