Thanks guys - I like the dremel / diamond bit. I'll try it ! Totally PITA. 1972 !!!! 4hp evinrude - runs like a top for the 1 hour used seasonally when the wind totally dies on my day sailor.
It was running HOT when I went to winterize it - I had just replaced the impeller last year so I figured I'd check the cylinder / exhaust plate for blockage and gasket issues. Snapped bolt on inspection. All was OK in there anyway !
Dropped the lower unit. Turned out that the copper tube feeding the powerhead and fed by the impeller housing was clogged ! Straightened a hanger, unclogged it - but now this snapped bolt is allowing exhaust plate to leak !
Aaah tinkering. But, I figure even a pro would have had that same thing happen too. Wife thinks I'm insane. I try to explain, some guys watch sports or do crossword puzzles - I fix things ! You should see my fully restored 8 hp 26" snowblower ! I'm sick - I know !
