I have a merc 502 with volvo dpx drive behind it. I am looking to replace my stock merc exhaust with 3 inch spacer with a set of merc gils, making a hp 500 clone. My question is what risers do I look for to gain the height of the 3 inch spacer. And if anyone has anything for sale please pm me.
Thanks
Dan

all 4 shipped to you for 200 5o hrs on them good shape

The real question is whether or not your exhaust holes in the transom are 3 inches higher. You may need a custom riser height.

My boat came stock with the 3" risers. When I switched to KE headers for a std bravo setup, the holes in the transom were perfect. I think a stock bravo gil will hit the same cutout as you have now.
