Hi all - you helped me years ago with my 71 Chrysler 55 outboard and now I am back with a new boat and new question/problem. I do not know proper names for parts so bear with me please....We just purchased a 77 Fiberform with a OMC 120 in it - we hooked up a hose to the sterndrive water connection and turned on the faucet and water started coming out of the engine (onboard) just below a large 90 degree elbow which is behind and about level with the carburetor....my hubby felt where the water was coming from and there is a small (drilled) hole to the left of two square type appendages - should a plug go in the hole? The battery was too low to turn the engine over but she did crank - will the water stop when the engine starts? Water was coming out of the stern drive like it should......but the other hole...sheesh wouldn't we sink....LOL. Hope someone can help - we did order a Seloc manual but that won't be in for a while and we want to get cracking on her!<br /><br />Thanks in advance<br /><br />Norene

Now my hubby is saying the water was actually coming from one of the appendages - there seems to be threading inside............man oh man I feel stupid.<br /><br />Norene

Sounds like drain plugs that are removed to drain the engine and manifold to prevent freeze damage during cold weather,and are meant to be reinstalled before using.AND removed agin after use if the weather is cold.<br /><br />DHP

Ayuh,.......<br /><br />It Sounds like a Drain for the Manifold,........<br /><br />My best guess is that either a 1/8th" Pipe Plug, or a 1/4" Pipe Plug will screw right into those threads,+ Stop your Leak.........<br />
