No. But its the educated guess of my marine mechanic who showed me where two very thin streams of water were “trickling” in down the wall while looking underneath the oil pan of the port motor through to the transom. It could be the y pipe I suppose but I suspect that can be best confirmed by pulling the engine and doing a visual inspection. I have had both steering pins replaced using the aftermarket kits so I know they are not the problem...

So...an update of sorts on the potential transom seal leak. Launched a few weeks back with an empty bilge. Literally putted over from the ramp to our slip and found the bilge with water in it (again). Emptied it out and dried it completely. Sat for a week at the dock with not a drop coming in. This would appear to suggest that the transom seal is fine...no?
Had to pull it last week for an impeller change (Overheating) and again on the short trip from slip to ramp, it was full of water again. Might get the mechanic to pull the port engine (where the previous mechanic saw a trickle of water) and check for cracked/corroded y-pipe or missing/loose hose clamps (Merc 4.3L V-6). Any other recommendations??

Update...currently being repaired. The port u-joint bellows detached at transom according to tech. Have also given instructions to do a reseal on all below the water line through-hull fittings and to replace port side transom seal as well as inspect transom. Will update when results are known.

Solved!!! Finally found a competent marine repair shop just south of Ottawa.
As noted above, the port side u-joint bellows was dislodged at transom (probably just above the waterline). So when sitting at the dock, no water would come in but as soon as the boat moved, it would permit water inside. Had them replace the port transom seal for insurance, and inspect the transom for de-lamination while the transom plate and drive was removed. The transom was reported to be solid! There was no evidence that the through-hull fittings were leaking so they were not replaced. No more water in the boat!! Happy day!! Will enjoy a few extra rum after re-launch

Curious, how much that service costs. I'll be having to do the bellows on my drives sometime soon...

Yup. The gimbal was replaced along with a new shift cable. They installed what the referred to as a Transom kit which, I believe, included replacing all bellows.

I had a bit more than the bellows serviced so it's a bit difficult to break it down. But I would think that if you know what your marina charges per hour and you get an estimate of the number of hours they will need to take care of it, then all you'd need to do is find the cost of the part(s) somewhere on-line to give you an approximate idea?

*Edit* Replacing the bellows sealed everything properly and they found no evidence that the transom seal was leaking. Therefore, the transom seal was not replaced. Sorry if I caused any confusion.Solved!!! Finally found a competent marine repair shop just south of Ottawa.
