Hey Gang
I picked up a 1974 Johnson Seahorse 6hp, the previous owner said it ran ok last season, but this season he could not get it to start...I quized him on what he did to try to get it running, he said "Nothing", I just want to get rid of it.
Paid $75 for it, clean engine. All original.
I got it running after half hour of pulling, and it would not idle, just mid-high power....
I did the following in my spare time over the past month or two:
Rebuild fuel pump
New fuel lines
Overhaul carb
It was still a bear to start, won't idle......so I pulled the plugs to check them, and WOW...found fresh clean water in the lower cylinder plug! Either a cracked cylinder or blown gasket.
Got a gasket, pulled the head, and yup...Blown.
Surfaced the head/cylinder, reassembled, and today took to the lake....>WOW!! Started on first pull, idles perfectly, and picked up quite a bit of power in top end!
With the other work, I have a solid, clean engine, to push my 12' Mirrocraft...for about $115 total out of pocket including the engine!
Here are a few pics of my head gasket job:
