Re: [Amel] Yanmar exhaust elbow

I should be at the boat in the next few days, I will take a photo of the exhaust
and the heat jacket and forward it to you. Basically there is a 90 degree elbow
right off the turbo going almost straight up, swept back some to the rear. There
is a straight tube, single wall, no water jacket going up from the elbow and
then another 90 degree elbow at the top pointing back down towards the muffler.
At the end of this elbow is a double walled, water cooled straight tube that the
exhaust hose attaches to with multiple holes for the water to eject for cooling.
The fabricator, who is a wizard at this, then had a custom made exhaust jacket
made that wraps around the whole thing and is held in place with stainless steel
springs.

In reading your note again, that is what the yanmar exhaust box looks like.

I would love to see a photo.

When I repowered my Maramu with a Yanmar, I had a stainless steel manifold
made
with a 20 inch rise with the water injection at the top of the riser. There
is
no water jacket to rust out as it is a dry stack to the top. I had a heat
proof
jacket made for the dry stack portion. The whole thing did not cost me
$1,000
and will last forever. You might want to look into that.

I contacted my Yanmar dealer here in New York, about the rusted out exhaust
elbow.

Yanmar has come yup with a solution. , a box like manifold with an exhaust
port on the bottom.

Manifold, hoses, and support bracket $1300- US$

What an insult.
