[Tiara Open] 38 open 2006 smell in cabin

[ReelMagic]

I own a 2003 38 Open and have never experienced a smell in the cabin (or anywhere else) when starting or underway with the cabin door open or closed... Is the smell a diesel exhaust smell? Not sure what would cause a rotten egg smell although diesel exhaust does smell somewhat like rotten eggs. Are your engine smoking black smoke when first started? Sure sign of something not quite right.M2C
