Re: Replace Yanmar Exhaust Hose

Agree with Tom! Be aware of the bend radius. Once the hose kinks it is trash.


Rule of thumb; the bend radius of a corrugated wire reinforced hose is 4 times the inside diameter of the hose.


IMO – Silicone hoses are better (and more expensive)


Coat the elbow and exhaust fittings with dawn detergent for an easier fit.



With best regards,

Just did the main engine exhaust from the mixing elbow to the muffler. Discovered how important bend radius is in the hose. Mine was 4 1/2 inches and I needed every bit of that plus some wrestling.
