--I am thinking you may be right about the transom seal. Although I suppose it could be the y-pipe too.
I just did some crazy cotortionist moves in the engine bay to see if I could get to the transom nuts. It looks like I may be able to get to four of them with the engine and y-pipe installed. Any thoughts on this Greg?
Also, Upon close inspection it seemed like there was a small gap at the bottom of the outer transom against the hull. I think I might be able to slide a business card betweent the transom mount and hull at the bottom.
Everything looked tight from what I can see from inside the engine bay.
I am seriously considering smeering some 3m 4200 or something similar between the outer transom bracket and the transom, putting the drive back on and running the boat for the spring/summer if it keeps the water out.
-thoughts?
Thanks,

Jay,
Most likely your transom is getting soft. Since the most force is applied to the bottom of the transom assembly and most water intrusion problems in transoms start at the lower end, it sure sounds like your boat has the telltale signs of a soft transom since you can detect a gap. Many times there will be spider cracks in the gelcoat at the bottom corners of the outside transom assembly due to outdrive's force pressing primarily at the bottom of the transom assembly. My two cents, Bill

All of the transom cut out on my boat was unsealed plywood. Even the garboard plug hole was unsealed. My wood seemed decent so I pour epoxy all over and brushed it in. I wouldn't be surprised by a wet transom in a boat this age but I would still look at the holes in the y pipe.

I think you're better off heating up epoxy and sucking it into a disposable plastic syringe to squirt into cracks than you are spreading 4200 into a gap. 4200 isn't runny. 5200 is a bit runnier though.

I think there should be a cruel and unusual punishment for people who cut holes in boats and don't seal any wood they cut through.
That's my $.02
Have you ever seen how fast people move when they realise they forgot the drain plug?
machinist ,bore it deeper,ream it bigger, and lap it to a fine finish

Good News Bad News. I dont have a leak anymore but I am pretty sure I Am due for a transom seal. I pukied up the outer transom with some lifeseal and tightened the transom nuts i could reach. ...going to run it as is for a bit

When you do get it opened up, use System Three Clear Coat epoxy to seal the transom wood with. It's very thin, and 100% of it will be absorbed. So much so, that after it's cured, it doesn't even look like it was sealed. I've never tried to use two coats, but it wouldn't hurt to experiment.
Use a PVC glue brush like one of these, the smaller, the better. But they hold a lot of epoxy;

Thanks to everyone that contributed to this thread. I had the same kind of problem and with the advice of everyone here I was quickly able to determine that it was the transom seal. After pulling the motor and getting everything apart I found that the seal had gone and the corrosion from salt water had pushed the gimbal out. The damage include a rotten core and there was more corrosion to some of the steering components and the back of the oil pan has a bubble in it. Today we are checking the water jackets in the block to see what kind of shape that is in and we're doing a compression check too. After today we'll make some decisions on keeping the 350 or putting a 383 in. Risers and manifolds are still OK, but marginal so those are getting replaced too.
I'm OK with everything that we're doing but I wished we had done it last winter and not in our prime boating season hear in FL. Hope to have it all back together by the end of the month.
