I’ve never used them but Threebond products have been around for a good while and they are commonly used for sealing crankcase halves.   They would work as an outboard crankcase sealer but if it’s a straight metal joint with no spaghetti seal, then I typically use Permatex anaerobic gasket sealer on my OMC motors.    It works great and is a lot easier to use than the sticky, gooey, messy 3M847.    The 847 can be used on crankcase halves that use a spaghetti seal but not a straight metal to metal joint.  I also used Permatex Moto-Seal to seal the crankcase halves on an Evinrude motor – it’s very similar to the Threebond products.

For sealing OMC gear cases, I recommend Permatex Ultra Black.   It’s WAY easier to use than 847 and seals just as well.

I am with bob on this post.  Those new silicone base sealers are great!  The bigger the glob the better the job?  Not!
