Johnson 115 Piston - Imgur
Here is the story: I had 105 psi on one cylinder (compared to 125-130 on others) and I uploaded the first picture in this album. The wisemen here said I was due for some trouble. Well it happened. The rest of the pictures are of the damage that happened not long after...

Hello everyone. Tomorrow I am buying my first boat in 20 years. It's an old $1500 16ft with a 90 hp Johnson outboard. I live in Milwaukee so there is ice everywhere except lake Michigan and the Milwaukee river. My question is: could I take it in the super cold river to just test it out or is...
