Default Gil Exhaust Riser Wedges

These were created on a CAD machine to raise or lower the height of the exhaust pipe at the transom. They are placed between the manifold and the riser with a gasket on either side. They were cut from the mounting bases of old Gil risers and are 3/16" thick on one side and 7/16" thick on the other. The amount of vertical movement depends on the distance from the back of the wedge to the transom but is approximately 9/16" for every foot of travel. Very useful if your transom exhaust cut-out is misaligned with the end of the exhaust pipe pipe. I'll take $200.00 +$10.00 shipping for all 4, which is less than I paid to have them machined. I've also got 1 blue silicone 4" hump hose, never used: $15.00.

Yes, they're cut from old risers.
