Indmar Exhaust Manifold drain for winter

kpair 09-21-2005, 7:32 AM

My Indmar 350 (carburated) has a hose on the back of the engine connecting both exhaust manifolds. The hose has a quick disconnect fitting on it. For winterizing, (specific to the exhaust manifolds) will draining the water from the hose and filling the manifolds with anti-freeze be good enough or are there extra drain plugs I need to open.

I have a 2002 Malibu Sportster LX.

Thanks

Thats it for the manifolds. However, the rest of the engine needs draining as well.

Got the rest of the engine. Scary thing, but I called the dealer and they wouldn't tell me what you stated. They said, look for other drains in the manifold and if you find them drain them. Thanks Tuneman.
