You wanna cut a hole in a "wooden" boat hull???

I propose cutting flush with the hull, and patching and glassing over whatever I find there - hopefully just a hole for the tube and possibly some bolts.

You may have to glass a better lip around the cut out unless you are very fastidious with your sawing.

Of course, another option, one which is more expensive but less destructive and labour-intensive, is to cut a square for an access hatch in the floor of this type:
The hatch is an interesting option.
Sealing the cockpit floor with a small person or large child locked inside would be cruel...
I will take a closer look and poke around the edges, I might find screws at the floor edge. I would expect the builder (a very competent amateur) left himself an option to get to the stern tube from the inside.

Re: Help: Prop shaft under self draining cockpit floor

It is a bad idea to have any inaccessible places, especially on a wooden boat. You'll be wanting to unbolt that prop shaft strut and remove the cutlass bearing and pound in good quality, wooden plugs in all. If you decide to just cut a temporary access hole in the cockpit floor, cut it on the bevel as you would the top of a pumpkin. I highly recommend you obtain a Bronze or galvanized, Baier lift out hatch. The plastic, flush hatches just don't stand the test of time and UVs. Someday someone will jump into the cockpit and keep on going.

That was a really cool installation with the variable pitch prop. I am sorry you couldn't have resurrected the entire system.

Re: Help: Prop shaft under self draining cockpit floor

Wood boats are sometimes quite structurally different than fg. You often cannot place an inspection port without compromising the boat. I suggest you visit the wooden boat forums online (sponsored by wooden boat magazine) where you'll find some very knowledgeable folks who will help you with great insights.

Best of luck!

Re: Help: Prop shaft under self draining cockpit floor

happy beat me two it. just saw all out the variable pitch pieces and remove the rest on the hard
volvo used to make a one cylinder without a gear box, you could pitch the prop in fwd neutral or reverse I pretty sure its the same thing

Re: Help: Prop shaft under self draining cockpit floor

Wood boat? Remove the shaft epoxy a wood dowel rod about 1.5 mm (.0625 inch) smaller than the diameter of the shaft log and about 150 mm ( 6 inch s) long. remove the strut by drilling out the bolts. plug the bolt holes with dowels and epoxy then screw and epoxy wood plank, the same dimensions as the foot of the strut, into the recess where the strut was. preferably using the same wood as the hull has. if not a comparable hard wood. also the thinner the glue in the mating surface the stronger it will be. and make sure all surfaces are dry.

Why cut out the cockpit sole? On the inside where the shaft log comes out? that big hunk of wood? that is more than likely the Keelson...ie...the back bone of the boat. Be happy you have all that room that the engine took up and still have a sound vessel. Not to mention if you follow the above, it'll be les work and cost. I'd only go through the sole if it had rot.

years ago, we have restored many Robert Tucker's designs in the 2 Wivenhoe shipyards in Essex / UK.
Don't cut out the cockpit sole.
