Waterproof Temporary Putty Sealant

[csommers79]

Hi -

I need to replace a seawater intake hose barb on my stern tube (which has a cutlass bearing on the prop end and a prop shaft seal on the end near the transmission). To do so, I plan to disconnect the shaft from the transmission and slide the shaft out so the intake hole on the stern tube is clear of the shaft. However, water leaks in to the boat through the cutlass bearing where the shaft protrudes from the skeg - I have been told there is a waterproof putty I can wrap around the shaft and cutlass bearing, that won't bond or set up, to temporarily keep water from flowing in - is anyone familiar with such a product? West Marine doesn't seem to know, nor does Lowes or Home Depot... Please email me at csommers79@gmail.com with any thoughts or suggestions! I just need a temporary patch of sorts to allow me to dry out the inside of the stern tube while I'm working on it...

You can get butyl tape at an RV store.

You can also buy it by the brick at Home Depot for $1.60 a pound.

Sounds like plumber's putty to me. It's used between the sink and the counter, or the faucet and sink. Never sets.

A toilet bowl wax ring would also work. Around $2 for 1 ring at HD or hardware store.
