5200 is awfully sticky. I have to seal the bolts and between the hole in the boat and the rudder port.

If you're never ever going to remove it, use 5200. If there is a rudder port removal in the future, use 4200 or something similar. I used polysulfide, 'cause I had some.

Rudder is all gooped in with 5200. Now on to final drive alignment. Building a cold-mold, straight inboard boat is a significantly more involved task than building the Malahini. I didn’t realize how many components are self contained in an outboard motor, drive shafts and bearings, steering, cooling water circulation, etc...

I’m setting up my exhaust, mufflers or no mufflers? What have guys done on their boats? I don’t want it to sound like a Bayliner but rumble just enough to not alert my wife to excessive noise.
Mufflers aren’t cheap either, $200 a pop.

It varies from state to state and country. Alabama (USA) law is certain DB at so many feet at idle. I looked into this on the Tahoe. The muffler would be really big! It's diesel 4 cylinder, single exhaust. By the time the exhaust goes through the turbo, wet riser, and rubber exhaust hose, it qualifies by a long run! No muffler.

Hi Matt,
You mentioned that the mufflers were expensive. You're right they are. The way I looked at it was the exhaust hose is expensive also. The mufflers that I got are the kind they put on ski boats. They are about 3' long so, 3' feet less exhaust hose on each side. Also no low spots like you might get in an unsupported hose, and I didn't want to get into a situation where someone complained that the boat is too loud. (lots of whiners in Calif.)

Thanks for the replies, I’ll let the moths out of my wallet and buy a couple mufflers.
Jim, I had the same thought about the price of the hose vs the muffler, less hose you have to buy. I’m going to have a $1000 bucks in this exhaust setup, it’s not like buying a couple cherry bomb mufflers from the JC Whitney catalog.

Any advice on muffler style, Long skinny or short fat ones? The engine had short fat mufflers on it, sounded pretty good.

Since the BB doesn't have a rear cockpit I think you can go either way. Look at how it goes by the fuel tank. The Tahoe would have to have the skinny one to get by the rear cockpit.

I would think the long skinny ones. Rather than connecting them to the engine like your picture shows, I connected mine to the exhaust ports with short pieces of exhaust hose. I added supports for them that are connected to a frame. I got stainless steel elbows to connect from the engine to the mufflers like Roberta did on her boat. With the two elbows, (two for each side of the engine) the hose can be adjusted for better alignment from the engine to the mufflers. Make sure sure you have access in your transom to tighten the hose clamps to your exhaust ports. (I cut access holes in my transom)

Help, This way or that way with the seacock position? I see current builds doing it both ways, Toms Tahoe and Aussie Belle.
I have no experience with water pickup plumbing.

My logic, such as it is, is that the seacock should be as close to the water as possible. A cracked fitting will stop leaking after I throw the valve. However, cracking an elbow or close seems REALLY improbable...

Tom, Agree, seacock 1st.

Shaft coupler mated to transmission, got it within .015 tolerance.
Prop to strut is dead on at a 1” gap, I was worried about that one.

That old ski boat was a great find. It's bits will live on in your Barrel. A much more attractive package.

For exhaust, I found SS thinwall tubing from a online fabrication shop.
The SS tubing was cheaper than flex exhaust hose.
Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! :roll:
