This looks like a disaster and it is..but I haven't took a picture since all the new hosing went in.

But could you not do something like this?

The green line is where my exhaust hose goes up to mid ship, about a foot higher then shown to a 180 degree fiberglass "U" back down and along the bilge and out amid ship on the Port side.

I don't even have a muffler!...the run is long enough where sound is completely absorbed by the water in the line...The back pressure is minimal and not a problem...total run probably 15'+

I showed up one day to paint the engine beds and they had the engine in already...Oh well nothing a 1" brush and a couple trips to the chiropractor cant handle..

The exhaust crosses over the tranny and goes into a box in the opposite corner from where it is lifted.
But also, mine is a Turbo
Since the dipstick locations are different, I suspect that there are two versions of the box. Otherwise they look identical.

There must be two versions of the tranny. Mine is the KM35P.

I've ordered up some special exhaust hose that will dog leg around the shifter linkage so I can use it the way it was intended. Pictures to come later.......

Well, I solved the vent loop problem. As you can see the fittings are so close that one can not even install 90º fittings but there is a fitting on the side of the exhaust elbow so I switched over to that one. Although the heat exchanger fitting still sticks straight out.

Since there were other factory made bent hoses I figured why not go to an auto parts and pick up some pre-made bent hoses to get around the tight spots and still get the "T" in the loop for the PSS hose. It looks a bit odd but it should work just fine.

Siphon Breaks / Vented Loops have a tendancy to spit raw water when the vent opens and closes when starting and stopping the engine. Make sure this spray is deflected away from the engine otherwise you'll quickley have a corrosion problem. I speak from experience!

Good job Del. Looks fine

Del,
adapt the little joker valve on the Forespar loop to a hose. Then run the hose down to the bilge.

My last one didn't spit a drop, we'll see what happens with this one, it's new, probably made in China.

But today I discovered how thick my hull was. I had to drill a new hole on the opposite side for the raw water inlet. The old one was too small and under the exhaust right where the shifter would hit.

Wow, that's impressive - Never heard of a Choate 40 before, just looked at one online, an interesting boat - Nice....

It's been sailing for 30 years, crashed the keel many times and still going strong. It'll probably out last me unless I decide to take it with me.

I found out today I also need a longer thruhull fitting.

Back to the marine supply.

What is she cored with? Choate built some long lasting boats.

delmarrey · 08-03-2010, 11:30

The hull is cored with a red foam, not sure what it is. But it must have came in sheets of squares like what balsa does. I can see breaks in the foam just like with balsa from the core samples I've drilled out. The horizontal part of the deck is cored in balsa but the upright sections are also a tan colored foam and the cockpit is cored in plywood.
