Replacement Risers for most gas and diesel engines:
A riser is essentially a pipe that makes the marine exhaust system go up hill in order to prevent water from the lake, ocean, pond to get into the engine.
If the engine is high enough above the waterline a riser is not needed. Elbows are used instead.
