Reply To: Exhaust pipe gasket

I think I know exactly what you are experiencing. The exhaust and excess oil does go down the inside of the exhaust tube BUT some does leak out around the outside of the exhaust pipe where the pipe fits into the lower engine flange. My exhaust pipe is polished brass and when this happens, it really doesn’t look good and makes a mess. This it what I did and it works to stop the exterior leak.
1-  I unbolted the power head to remove the exhaust pipe.
2- clean pipe and inside of flange thoroughly to remove oil and grease buildup.
3- I used Permatex ultra copper high heat silicone and put a SMALL bead (think of how small the area is where the oil is coming out and don’t overdo the silicone) of silicone inside exhaust housing half way up in the housing.  Slip pipe in, spinning back and forth a little to coat pipe while inserting into flange.
4- put power head back on aligning everything up and let silicone cure 2 days.
