I have a Mercury 300x on my boat that has been sitting for some time. 3 years with little use. I freshened up the gas a bit but never touched the injector oil.
Last trip one of the motors poped a bit at idle but then cleaned up and we we headed up river. Two miles up river one motor stopped. I could not get her to turn over.
I limped back to the dock on one running Motor and pulled the boat out of the water. The locked motor would then turn over but I didn't fire it.
A Mechanic put a bore scope in and said I have some scoring and damage on two cylinders.
He called me today and said he talked to Mercury and they sell the head for that motor for $9000 plus (core) plus labor and parts to tear down and replace the other stuff. BIG BUCKS Ruined my day a little.
I am blown away. These motors have less then 190 hours on them but assume I should have been more careful with the gas and oil situation. Dont know if that oil or oil pump gum up from sitting. Kind feel like
I should have cleaned and serviced them
Is it true these heads are not honable? If we tear the engine down and there is just some score marks I hate to spend that kind of coin to fix this.
Who should I talk about these 300X motors?
