I just sold this boat & I am de-winterizing it for the new owner today. There was a lot of -40 antifreeze put through both of these engines last fall, but 2 frost plugs popped on the stb. side of the Port engine. The Stb. engine is OK. Does anyone out there have any experience with this? I am hoping that the exhaust manifold doesn't have to be pulled to get these plugs back in. Can these be re-used or should I get new ones?

LauKe: Purchase new Brass core plugs at an auto parts store, they only cost a few dollars. Original plugs are probably steel, brass is much superior. Take old plugs to store for size matching. Definitely do not reinstall a popped plug. Recommend purchasing a properly sized core plug driving tool in-order to install new plugs without damaging them.

Thank you very much for your advice. I will look into purchasing new plugs tomorrow.
