Hi my son has the above motor and has been having issues and has been paying a mechanic a lot of money and still has issues. He gets the overheat alarm. So far they have said it was salt clogged because of improper flushing and changed the thermostats and the water pump impeller and said they back flushed the motor., Now he was told they have to pull the heads to properly clean the water passages, so he came to me. He is almost 2k into this, I need to know if it is a big deal to pull those heads, don't know if he has a manual or not, I asked, he did not respond. I have been working on smaller motors all my life, the biggest were a 70 Hp Johnson and a 40 Merc 4 cylinder and on down to sailboat motors.
The boat will be here tomorrow afternoon. he was flushing after use with a flush plug in the side of the cowling and not running it.
First thing I plan to do get it running with ear muffs and listen to it and then check the temps with my point and pull the trigger thermometer to get an idea where the heat is
Need advice, help please
