Water leaking in around shaft on inboard

ripcurl2785 · 09-10-2008, 08:10 PM

I have recently noticed water slowly leaking in around one of my shafts. This is the first boat that i have owned that is an inboard and im not to familiar on how to adjust (tighten down on the nut i assume but not sure which way and how much) and not sure how to tell when the whole thing needs to be repacked of whatever.

Do a search engine on "Repacking the Stuffing Box".

It may not need re-packing it may just need a little tightening, but don't over tighten or you'll be re-packing shortly after.

You'll need a couple of plumbing wrenches.

It's easy.

ripcurl2785,
hum, there are a couple of different kinds of stuffing boxes, one is called a dripless and then you have the ones that require packing. The later should drip most all the time as water is what lubricates them. If you have a nut on yours I would say that you have one that has a packing, but remember that it should leak some...

Rip-

I think if you post up a couple of pics, we could probably give you a better idea of "exactly" what you need to do......

I second that, we want to give you the correct information the first time. Over tightening the packing will burn it up and may also damage the shaft.

SOME SHAFT NUTS ARE HARD TO ACCESS IF I CANT GET WRENCHES ON THE NUTS I USE A SMALL PUNCH AND HAMMER. FIRST LOOSEN JAM NUT [LEFTY LOOSEY] TRY TO TIGHTEN PACKING NUT BY HAND,YOU WANT A DRIP ABOUT EVERY 5 SECS, IF U NEED TO PACK GET APPROPIATE SIZE WRAP AROUND SHAFT CUT WITH RAZOR ON ANGLE DO 1 PIECE AT A TIME, ALSO TEFLON GREASE [MERCUARY 101 ] WILL HELP TILL U PULL BOAT

to identify what type of seal you have, show you how your shaft seal works and what you have to do to maintain it.

This is not a system you want to DIY lightly - make a mistake and it can sink you!

lets "assume" its an old style stuffing box with packing. it should drip one time every three seconds. . if its "dripless" then it shouldnt leak at all. over tightening an old style stuffing box will cause the shaft to over heat and snap.

Yes it is the old style stuffing box. I will try and post some pics this afternoon
