Title: I/o leak.
Post by: dezerttoyota on June 02, 2014, 06:49:38 AM: Is there a common place were I/o leak. Im leaking a little bit of water into the bilge area. About a gallon an hour and cant figure out where. The bellows are new.

Post by: ka0tyk on June 02, 2014, 11:13:59 AM: theres the water pickup tube, the shift cable bellows, and the bellows. the exhaust bellows wont let water into the boat, it'll just be loud at the gimbal.

also inside if you have thru-prop exhaust there is a small seal where the Y pipe bolts up to the transom assembly.

shift cable bellows

it probably leaks less because you're stretching the bellows and closing the hole up. id check the main driveshaft bellows and the shift cable bellows.

What drive?

How high does the water need to be before you see the drip?

If you are going to do anything, I would recommend drilling some holes (inside the hull) and squirt some Boatlife "Git-Rot" in there to fill in where the wood rotted away.

Pretty good chance it will save the rest of your season anyway.

Not sure the foam would do a damn thing.
