today I took my 19ft peterborough out for it's 2nd ride of the year. when I left the marina, it was not running on all 4 cyls, so I slapped in some new plugs. then away I go on my merry way. this is an old early to mid 80's 4cyl, 3.0 liter 140hp omc....the blue block. I was giving it a few shots...
