| I purchased a 2005 boat a couple of years ago. It came with a Mercury 200 EFI salt water version. The motor had very low hours (60.1). As it turned out everything works great on this boat. I haven't had any problems with the motor but I noticed that the water stream from the pump was weak and spitting at times and not a constant stream. If I put some RPM's to the motor the stream would get better. I never had any warning tones that the motor was overheating. I thought the impeller may have dried out or chipped with age so I replaced the impeller last year. After replacement I was sure to get that solid stream and was disappointed that the results were the same.
Does anyone have any experience with this and a solution to this issue? I'm sure this is not normal. Every other boat motor I see even when idling has a solid stream of water spewing out their motor. My 9.9 kicker motor has a stronger stream then the 200 hp. Any help would be appreciated. |

Location: davis,IL | This may be completely normal as this is just an indicator that you are pumping water. My Yamaha 150 has a fairly weak stream when compared to my Merc 5 kicker, but all is well. I have a temperature gage mounted on my 150 to monitor just that....engine temp. If in doubt mount a sender and gage on the big motor, that way you can always watch whats going on there. |

| I had the same concern once. It is just an indicator that water is circulating. Make sure your overheat alarm is connected and stop analyzing it. I have a habit of over analyzing things. |

| I've had mine get plugged a time or three, usually by weed fragments that get ingested by the impeller. The fragments seem to get stuck right at the fitting that connects the pi$$er tube to the engine block, which on my engine is a 90° elbow about 2 feet in from the end of the tube. I now keep a length of fairly stiff weed-wacker line in the boat, line that fits into the tube and is long enough to reach the fitting at the block plus enough to hold on to. A couple of rotations of the line after it's fully inserted is usually enough to clear the pi$$er tube. |
