Water Leaking into Bilge from Port Exhaust

[Begester]

I have a 1989 SeaRay Cuddy cabin with a 5.7L Alpha 1 gen 1. Freshwater cooled. I had the engine bellows, shift cable bellows and gimbal bearing replaced last week and picked it up from my mechanic on Friday. I ran the boat for about 4 hours on Saturday and had about 7 gallons of water in the bilge when I pulled it out of the water.

Got the boat home and filled the bilge with several gallons of water and put the drain plug in. I see a slow but steady stream of water dripping from the port side exhaust port on the outside with the engine off and am trying to figure out the problem.

The leaking occurs when the engine is OFF. I drained the bilge, reinstalled the drain plug and ran the engine for a few minutes on the muffs. I did not see any water, but didn’t want to run the engine too long in case there’s an issue here.

Any insight on how to best trace the root cause?

putting water in the boat and seeing at the exaust relief ports indicates a leaking/corroded Y pipe

If that is the case then if you started the boat on the muffs with a dry bilge then you would see water coming out of the exhaust on that side but it should be way down by the bottom of the bilge. Did you have this problem before the work was done? Unfortunately this is one of the problems you have with older I/O boats, you get corrosion in the Y pipe, or on the sealing surfaces between it and the exhaust housing on the transom plate so that the gasket no longer seals. Requires an engine pull to fix.....

I hope you are done starting new threads on this same subject. 6 times in 15 minutes is 5 times too many.

Begester I guess not. Stop starting new threads!

Thanks very much for the information, is there anything I can see from the inside that would confirm this? It doesn't look overly corroded down there but I could be missing something

PS: My apologies on the duplicate posts, it kept giving me an error message.

Lou - Are you saying I'd see the water leaking inside of the engine bilge with the motor running? Will try again but I didn't see that last night

If your Y pipe is corroded and the engine is running yes you could expect to see water running out of the Y pipe or behind it but it may abe way down by the bottom where it would be hard to see. Eventually you should see an accumulation of water though.
