what's to prevent you from raising the mixing elbow? that way you'd have more room for the waterlift, and clearance to plumb the vented loop......just a thought.

Actually metal against wood is pretty slick. It was too easy. I used the windless to pull it forward under the hatch and block/tackle to pull it back (almost too far).

Sailmonkey: I would have to build a "Z" riser off the back of the manifold and that wouldn't be cooled.

Mines not cooled either......just some insulating wrap and monel wire.

This isn't mine, but very similar....except I've got a mixing elbow on top. When the engine is running I can touch the wrap.

Amazon.com: exhaust wrap

Nope! It's good.

BTW I wouldn't need the vent loop then. It's to keep water from back flowing thru the elbow, which would be well above the waterline.

True,
I've got both, as the elbow is still below the heeled waterline when beating hard though.

My engine is 1990 Vintage, and it is a Turbo. I will check out if it is similar and post pictures.

Been think though!
That elbow is pretty heavy (solid bronze), about 5 lbs. The leverage against the studs with the shaking of the motor might cause the exhaust system to work loose a lot. Don't want any fumes leaking into the boat!

Del, I don't think you can just use an elbow like that picture. You exhaust manifold is cooled in part by salt water, so injecting the water at the elbow wouldn't work in your application.

Note that the photo is of an older Volvo motor, not a Yanmar...

I'm confused as hell.......what does this mean? I have a phasor....just like a yanmar, the seawater passes through the heat exchanger (exh manifold) then into the mixing elbow, that just like the picture, is mounted on some pipe. True that is an older volvo in the picture, but I've done this to many modern engines too. sometimes this is the only way to assure the exh is above the waterline, or to give sufficent room to put a waterlift in where space is limited.

FWIW on my 43 Irwin the Tranny is the mirror image of what you have.
Looking up from the shaft to the box, the dipstick cap is on the left (Port) side where also the exhaust comes out. The shifter linkage in on the Starboard, and in my case, being a Center cockpit, the cable goes up straight from there.
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.
