Title: Slow Leak From under engine
Post by: dlarusso on August 05, 2026, 12:29:55 AM
Hoping to get some ideas on where this slow leak is coming from. I've tried baby powder, paper towels around the hull, seacocks, etc. etc and those all seem to be dry.  The one spot I see is a small trail of water coming from under the engine - but not FROM the engine. The engine seems to be sitting on a mount of some sort and there is now water directly below it...but I did notice it has a small gap under it and can see a slight water line.  I have an '85 P303 with a 2GM20F.  The pics attached show where it is leaking (about 1/2 gallon every 3-5 days. Sometimes slower and I can't find a pattern of when we sail vs. when we run the engine vs. when she's just sitting in the slip - it still comes at different flow levels that don't align to any one use case. 

Any thoughts or tips here? I'm on the verge of pulling her out of the water to see if something strange is up on the hull.

Puzzled by this...many thanks for any thoughts.
