"I have the infamous Mercruise
"I have the infamous Mercruiser 3.7 165 in my starter boat. The engine has been great for the most part over the last 2 seasons.
At the end of the last season the boat developed a strange problem. The tachometer would bounce around, typically above where the engine was running, and at certain RPM's the engine would sputter and seem to make a popping noise out the carb.
The only thing I have done to the boat in the year that I have owned it is have the carb rebuilt, changed fuel filter, and change the oil. I am going to be replacing the coil, wires, cap, rotor, etc at the start of this season, but I was curious if anyone has heard of a problem like this.
Thanks,
Eric"
