Mercruiser Y-Pipe Insert Caps


Mercruiser Y-Pipe Insert Caps

These caps are commonly used when switching to a thru-hull exhaust system when the y-pipe is no longer needed to route the exhaust. Instead of pulling the engine to remove the y-pipe you can now easily slip these in and clamp them down, easy as that. Oval Shaped for Mercruiser applications. Made of stainless steel these caps will be good for years to come. Sold in pairs.
