    Does that merc have a spaghetti seal? I have used the 847 on vintage motors with spaghetti seal.

    I am straying away from it now however. It has "fillers" in it, and is not anaerobic. Works good for gearcase skegs, sealing water pump plates, things like that, but I am not a fan now for sealing crankcase halves. Others may disagree with me, but that is how I feel. It starts to harden before you are done, and you get leaks. Not the best product anyways.

    Loctite 515 or 518 are good options. the 518 being a bit better if you can get it. Or OMC gel seal, just follow the instructions to a tee!
