Beautiful work, you could make a lot of money here.

Mounting same as Broadbill,countersunk holes drilled thru hull with 6-32 stainless hardware nylocks inside

Lostsailor - your exhaust seems high, above deck level. I've struggled with routing of exhaust on my W36. How is yours done?

It comes off engine,passes under deck through the compartment with water tanks,thru into lazarette,where fiberglass muffler is,and was all replaced when I bought the boat,the exhaust had 0 hrs on it

Any idea why the exhaust had been redone? I bought Weebles, my 1970 W36, in 1998. The engine is early 1980s vintage so had been replaced. One of the keys to the W36 being such a great sea boat is her low A/B ratio. However the low stance makes a proper exhaust difficult. Mine had a high outlet too - there was a check valve just inside the hull at the stern (I thought it was a muffler, but it wasn't).

Finding good advice proved elusive. Having high point of exhaust be the thru-hull outlet defied logic to me. I asked a lot of knowledgeable people and got a lot of conflicting feedback. I ended up running the exhaust higher at the aft end of engine room into the bottom of a galley cabinet, then running aft. This puts the high point of exhaust well above the outlet. I feel like I've finally got a decent exhaust system, but it took considerable redesign. I'll post a better sketch at some point.

Peter, not sure I have posted these pictures all together before, but here are two annotated photos and a sketch of Hull 34’s exhaust. It has been in service for some time on a 4-236 as you have. The inlet to the fiberglass goose neck is vertically above the water lift outlet, then everything is down hill from there. The goose neck is to starboard of centerline so the hose passes just inboard of the stbd water tank. The exhaust outlet is just above the water line on the Starboard side.

Sounds like you have created a similar system, it should serve you well.

You did post this over a year ago when I began my search for an exhaust solution. I originally discounted it because I didn't want the exahust loop in the middle of the saloon. I received input from many folks including some extremely knowledgeable people on this list. No matter what I did, I never felt comfortable with the outcome.

A few months ago a good friend of mine who knows more about marine diesels that anyone I know (his resume includes senior technical positions with John Deere, ADE, and Northern Lights) happened to be in Ensenada. He suggested your same configuration and when I looked, my entry doors are configured differently so I could actually hide the loop in the existing cabinet by installing a false floor. At his suggestion, I went with an off-the-shelf U-bend from Summit Racint in 304 stainless - about $60 so easily replaceable. (HERE).

Over the years I've noticed that Willard 36's have a relatively high incidence of replacement engines and such; or, as is the case with Lostsailor's "Broadbill" and my Weebles, some changes in exhaust layout. I realize these boats are now between 50 and 60 years old, but still strikes me as a lot. I have to wonder if the difficulty in exhaust is a key cause of early engne demise. Only speculation, but I do wonder.

At any rate, I spent a LOT of money on various exhaust solutions. In all fairness, I have never had a related issue or failure, but what I had never felt 'right.' I know feel very confident the high-loop I installed is the basis of a proper exhaust system that will serve reliably for many years.

Many thanks -

Peter

Looks nice Lostsailor - I like the font. Good to see a 50+ year old boat with it's original name!

I didn’t have the heart to change it,might be one of the only Willard’s still with original name

I don't blame you. It's a good name that befits the boat. In my opinion, owners give boats names that are meaningful to the owner, but not the boat.

The picture of Weebles on my profile shows her as "Taras" when launched in 1970. It was given to me by the then-owner of Willard Marine, Bill Angle. By that point I had owned her about 4-years - her name when I purchased was "Shy Platypus" which would not due so I went with Weebles after the venerable child's toy that can't be knocked down. Runners up in the naming was Atlas and Hercules. Had I known her original name when I purchased, I would have reverted back to Taras (some sort of Greek god of the water) out of respect and posterity - she was locally known around Newport Beach and was a committee boat for a few Newport-Ensenada races.

I know of no other Willard that has retained it's name over the years. A possible exception might be "Rattler," W36 Hull #1 (1961). I've lost track of her, but last I saw her 15-years ago, she was still Rattler. Another good name for a venerable boat.
