Hi,
First post. I've got a Nissan 18hp 4-stroke remote steering 2003 model year. It's been running progressively worse over the last two seasons. Here's the whole story.
First, let me say, this started after I foolishly tilted the motor up while idling to get at a bunch of nasty mill foil wrapped around my prop. I realized my mistake within seconds and killed the motor, but perhaps some damage was already done. Here's the sypmtoms.
Motor idles fine, runs fine then, suddenly, it will drop rpms, power, speed and almost seems like the prop has stopped spinning. Then, after a few seconds, it picks back up, then randomly, it will happen again, and again. It happens at almost all speeds and durring accelleration. Any time.
It got worse over the course of the summer and this year, after changing gas and heading out with clean lines, drained bowl, fresh gas, it's so bad it won't even get past 3-4mph. Now it's really chugging. My friend says, clean the carbs. Does that sound like the best first step? On another similar thread it was related to the fuel pick up and tempermental carbs. Any suggestions. Thanks.
