I posted this on the Moomba forum too but thought you guys over here might have more experience with the DD's since Supra has had them for years
During winterization this year I noticed my silencers were leaking. I didn't notice really any water in the bilge during the season or an abnormal amount of fumes either?
I haven't taken the UltraMarine Silencers off yet but looking at them they are BOTH leaking on the engine side of the silencers where they diameter of the muffler widens. Looks like they are both cracked and flaking off there. How long should they last? Seems to me that 3 or 4 seasons is a little premature for failure?
Should I use OEM replacements or is there something better out there?
And is there any way to drain the muffler/silencers in a DD for the winter?
