My previous IO had a plastic wing nut for the block but a small brass plug for the manifold. However since I was draining after every trip(I never left any water in engine when not in use) I had to keep spare plugs on hand. The key is not to over tighten them so they break or strip out. Just a little tweek is enough to keep them from vibrating back out. The brass plugs were susceptible to damaging threads.
