Default 85 hp Yamaha clogged water flow

I posted about this motor on "spark plug blow out" a few days ago. This is a 3 cylinder, 1990 model 85 hp motor. We've since determined that water flow may be inhibited between the powerhead and the exhaust ports due to salt and corrosion. Outside of pulling the powerhead, is there any way to clear those outlets?

nope. however if it got that hot and the engine did not go into slow and/or the horn did not sound you have other issues as well.
