The Captain's Take
I've seen firsthand the damage that can occur when a manifold or riser sits too close to the engine block. Overheating, corrosion...it's a nightmare. A simple Sierra Manifold Riser Spacer eliminates that risk. It's a preventative measure that I recommend to every boat owner. Trust me, it's a small price to pay for peace of mind on the water.
