Look at the shaft and the rudder as 2 obvious choices.

Make sure the bilge drain plug is tight too.

Then it's a matter of seeing what else you might find leaking.

See if the leak only happens when the boat is running or if it leaks while parked with the engine off to help you narrow things down.

There are lots of other penetrations through the hull like the strut bolts, rudder port bolts, anything attached to the transom like a swim platform that might have been added, exhaust hoses and their clamps and the exhaust outlets in the transom.

Cooling system hoses, raw water pump seal, freeze plugs, drain plugs on the engine.

maybe speedometer tubing leaking and a few other things I'm sure I missed

I'd vacuum it out on shore so it's good and dry, then launch and look.

It might be like watching paint dry ..........or may be easy to find


Thank you. I will get on this as soon as this series of storms blows through, and check off the list that you've given and anything else I may find. Based on the amount of water, I feel like it will be obvious once I start really looking for it. It has to be a pretty steady flow.

KENO gave good advice. I would start by looking at driveshaft packing and rudder packing.

If you are close to a launch ramp, remove engine cover and whatever else you can so that you have an unobstructed view of the rudder and transom. Drain bilge and reinstall bulge plug. Get in the boat and have a helper back the boat down the ramp. You don’t need to launch the boat at this point. With the boat floating on the trailer, you can look for water seeping in. Use a flashlight.   It should be fairly obvious. This is a good time to start the engine and see if there are cooling system leaks. I like to put the transmission in gear and run at idle — while The boat is on the trailer. This gives you a good opportunity to see the driveshaft packing. You should only have a drip every 10 seconds or so. Others may say more and others will say less drips.

Let us know what you find.
