Big leak in back of boat

[weezzell_5400]

I have a pretty significant leak from the back of the boat ...I think I know why...the biggest o-ring seal in this attached pic got left out by accident ....would this let the back of the boat fill up pretty fast

That big square cross section O ring needs to be in place. But if the bell housing face gasket was properly installed and the nuts torqued up to 50 fl lbs, water should not be entering. The face gasket is the first line of defense. the big O ring is a back up. Something is wrong. Pull your drive and see if the drive shaft bellows has water in it. If it's dry there is a leak somewhere else. Lots of possibilities. But if the leak started with this seal kit, start over.

Get a new transom seal kit and put it back together correctly. The water pump passage O ring should be stuck in place with contact cement. I do the same with that big O ring.

it would have to come thru the gimbal bearing first a constant pee stream but not a gusher

Its pretty much a Constant stream and is coming from higher up on the transom wall a far as I can tell...have not had it out this season...but plan on it ...

if its coming from an area directly above the shaft that is a vent hole to the bellow, Water from there is leaking bellows

You said you haven't had it out yet - does that mean it is leaking while running on muffs?

 

[weezzell_5400]

No ..not leaking on muffs ....just have not had time to get on the water yet ...either been working or its raining
