Water leaking by spark plugs

[getawaylamp]

It looks like the jacket water gasket is leaking on my 40hp Merc, water is steadily flowing out from beside my spark plug. I know I need to replace the gasket, but I`d like to try to seal it with something to get me by for the summer. Has anyone tried this? Does anyone have any tips for what to use and how to do it? Or is it fine to run like this for the summer, and just replace the gasket in the winter? Here is a quick video of it.

No quick fix for that and you will probably break bolts off.

Yup, I would fix it.
You could run it leaking if your just farting around but I wouldnt take it on any trips.
Use a torch and heat the crap out of each one before hitting them with an impact, set it low to start, they are small bolts.
Good Luck!

Dry it off and apply some silicone caulk

Replace the gasket.----Using heat on the block ( where bolt threads in ) will help getting bolts out.

My 50 hp did that around cylinder plug 1, but not as bad. I bit of silicone has fixed mine for 2 years so far. I'm afraid to break the bolts off until I have no choice.
