Should I use grease on a splined prop shaft when reinstalling the prop?

Thanks TMC. My boat is a 07 and when I removed the prop the splines were dry so I wasn't sure if grease was required.

Grease will likely wash away. IMHO Nev-R-Seeze or similar may be a better choice than just grease. I keep trying to remember to do that, but keep forgetting. I might be more inclined to do it if I were using a stainless steel prop.

I have always used the Lubrimatic in my tapered shaft, inside the prop hub and on the key to keep in in the slot while mounting the prop. After 9 years when I ran a chromed 3 blade the grease was still there, cause the hub/shaft/key made a seal in the front and the nut sealed it in the rear.
As far as the splined shaft someone else will have to confirm as the whether the grease is washed out over time.
