23' inboard Restoration

[heynow2203]

So I started removing the core on the gunnels and found that they are paper thin and I blew thru them just trying to remove the old balsa core. Wondering what would be the best corse of action repair or repair and make a mold From the old gunnel and make a new cap all the way around? and body already have a mold?

Last few days been busy painted the bildge.I grinded the cap and found how bad it was. I will start repairing that soon! Also will be setting the VW the beginning of next week so I can rig her out

Is there any way you can recore with plywood? The cap itself looks pretty tricked to mold, so I am planning to try to beef up my busted one. In between backing plates and enough layers of mat, I think a 130 on a bent butt should be ok.

ya thats what I'm going to do just need to lay down some fresh mat first to stiffen the hole thing up then re core then beef up the rod holders with some cross bracing and glassing it in . I've had 130's blow gunnels apart with the fish spiraling vertical with the boat i don't want to lose a big fish cause of chitty glassing

I was wondering what i should do for an exhaust system on the boat since the outlet is going to be under the water line most of the time. Should I just use a flapper and a wye surge tube? or do the make a inline underwater muffler I can't seem to find much info on this matter (or just don't know where to look!)

I am just talking through my HAT here so take it for what its worth.

On all inboard engines you have to be aware of static lift (so I am told) what it is and how it works is beyond me. Except that if the exhaust risers are to low you will (can) suck in water.

On the last true in board I had the exhaust ports where at water line level and they had flapper vales on them.

I am sure someone will chime in that knows a whole lot more than my garble.

The plastic fitting in the last pic would have to go.

I did a surge tube, a muffler and an exhaust port with a flapper. I do not have an inboard, but a jackshafted I/O which is similar in regards to engine location. I do not have a riser on my D6, but even with 12 guys in the boat and the motor off I did not have any problems. You may not need the muffler, but I do recommend the surge tube and the flapper. If you want to see mine feel free to check mine out in Chatham. I will look for some pics.
There is also another 23 inboard in Chatham with a D4, you may want to cheeck out what he did (Dmese on the site). He had a special exhaust made from stainless that was pretty cool, but I don't remember if he did a surge tube or a riser or both.
