May want to pull the prop and see if you've got some fishing line down in the prop shaft seals - friction will cause the mono to melt and build up on the shaft and ruin seals ... Just one thought

You need to clarify your post. Your subject says lower cylinder which is the engine. Your post says lower unit which is your gearcase. :( Whichizit?

Sorry, it was the lower cylinder. Found the problem, it was a small hole in the baffle plate.
