Default Main seal leak (case halves)

This summer she started leaking oil, underneath where the skid plate is. Obviously I tightened everything down right away. No luck. It starts by the drain plug, and goes forward from there. So there's a 3 inch stretch that leaks. The motors out for the winter. Any ideas on stopping that leak?? I have no experience splitting case halves, not something I want learn either. Wonder if I bring the motor to the Kawi garage, let those guys deal with it. God only knows what the bill is gonna be for replacing that main seal!!!

funny how oil can migrate around and follow seams and such. Are you sure that's where it's coming from. Hate to see ya do major when its a minor problem?

Nice to know there's not even seal! Put a piece of bubble gum and call her good! High temp silicone? What's gonna stick to that motor for awhile?

I'd tighten all the case bolts and not worry about it unless it's pouring out. Almost all modern engines are put together w/o anything except gasket maker (like Right Stuff). I was surprises how loose my case bolts were the first time I checked. (Don't go crazy and break one off though)
