View Full Version : stuffing box hose leak

11-08-2004, 12:46 PM
Anyone replaced the hose where the drive shaft goes thru the hull?
I am pretty sure I found the leak on my '94 225VRS. Will I have to pull the shaft to replace the hose? Is this a job for the dealer, (special tools)? Has anyone tried one of those shaft sealer systems listed on skidim as a replacement to the packing/hose setup?
Thanks and regards from Plano,Tx.

Are you sure it is leaking through the hose? There is suppose to be a leak at the packing between the two bronze fittings. This can be tightened to slow down the drip but you want about a drop per second. this acts as a lubricant for the shaft. If you have a hole in the hose I would go ahead and put in a dripless packing and don't worry about it in the future. The shaft would need to come out to do this. Also in plano

thank you for the reply.
I am about 90% sure it is the hose, BUT I will loosen the lock nut and tighten everything up and test again. How much should I torque it down? Not easy to work down there.
It was a steady stream leak, causing the auto bilge pump to come on about every 30 minutes. running or not.
got to ski in November last weekend. beautiful weather lately in dfw eh.

Do not over tighten the nut that is attached to the hose, this is a packing nut and should be adjusted with some caution, if you overtightenit it can burn and score your prop shaft. If it is to loose it will leak.

If you determine that the hose needs to be replaced it isn't that difficult. Disconnect the shaft and slide it along with the prop as far back as it will go. Then remove the existing hose and clamp a new one on. The hose is a special radial ply to resist the rotation of the shaft, It ran me around $13 from the local MC dealer. When you install the new hose you will want to replace the packing in the packing nut attached on the transmission side of the hose, this too is available at your local dealer. There are a number of threads available on how to replace the packing.

I agree... it's probably not your hose, rather your packing nut. This should be tightened to the point where it drips once every 30 seconds while in gear.Depending on how old the boat is, it may be time for new packing rope. The folks at www.skidim.com (http://www.skidim.com) can help you out there.

If it's that much of a pain, I'd go with the dripless PSS solution that skidim sells. I did that about 4 years ago & never looked back.

I appreciate the boards comments.
The leak looked like a constant squirt from the underside of the hose.
I have yet to try to tighten the nut and test, but will asap. If still constant leak, I will order parts, remove/repack/replace.
The boat is '94 225VRS TBI w/ 150 hrs. (new to me since August).
It obviously had little use and knocking a few cobwebs off is expected I guess. (so far I have replaced tranny cooler, plugs, wires, fluids, filters, and a few odds/ends, needs fuel sending unit replaced too)
Thanks again for the advise, really. :toast:

Looks like yall had it correct, the nut not the hose.
(In yer best bevis/butthead "nut, hose, ehehhehe")
Being my first true inboard, the stuffing box was new to me.
Dang packing was toast, the nut backed off and I assumed I was taking on water from the notorious seam b'tween the hull and the integrated swim platform on the early V225. By the time I fiigured it out the threads on the packing nut were buggered up making it a bain to get started. Couple hours of thread filing and two small clamps using the locking nut to "pull" the packing nut w/ it got her started.
I also used that new GFO packing material when putting it back together. 3/16".
Couple good links on the subject...
