I BOUGHT THIS BOAT TWO MOUNTHS
I BOUGHT THIS BOAT TWO MOUNTHS AGO. I JUST SPUN THE RUBBER HUB IN MY PROP. THE GUY AT THE PROP SHOP TOLD ME THAT THE POWERHEAD IS RUNNING TO HOT. THE OPERATING TEMP WAS 190F I THOUGHT THAT THIS WAS NORMAL UNTIL I BOUGHT A BOOK FOR THIS ENGINE.
THE NORMAL TEMP IS 130 TO 145F.
REPLACED THE PROP AND THERMOSTATS AND POPPET VALVE NOW THE ENGINE WILL SMOKE AND RUN BAD AT IDLE BUT WILL STAY AT 140F.
WHEN I SPEED UP THE ENGINE ANY RPM AFTER 2500 THE ENGINE WILL RUN AT 190F I HAVE NEVER HEARD A TONE FOR OVER HEAT.
I SPOKE WITH A LOCAL MERCURY SHOP HE SAID THAT I BLEW THE CYLINDER HEAD GASKET
IF ANY ONE CAN HELP
NOTE I AM AUTO TECH BUT NEVER WORKED ON OUTBOARDS BEFORE THANKS ANYONE
