Hello,
I just picked up 1999 25 Hp Johnson Outboard. I saw it ran in the barrel a minute so I bought it. I did compression test and all 95/93/95 psi in all 3 cylinders. At home in barrel, it ran for a while and I saw the smoke came behind the CDI box. I removed the CDI and saw a crack in the block. I also removed the cylinder head to see if it had the crack on the cylinders but all the cylinders looked good. Mechanic said that BJ weld should cover the crack.
What is your opinion? Should I tear down the block to inspect? If I tear down the block, I may do a quick honing on the cylinders.
