Hi Guys
I got a good one for you.....
I have a 1967 Glastron Tri-Hull with a Mercruiser 120hp 4-cyl.
The Motor runs great for awhile and then the #1 cyl. plug comes apart and blowing out of the head (not the thread and all but just the ceramic part). It looks to me that the plug is getting really hot because the plug boot is melted to the plug. This has happen twice to the same cylinder.
Any thoughts?
Thanks
