GT-40 MY 2001 SN

Good afternoon All,

I am hoping that you could provide me with a little help. I have been having an small on going issue with my boat since shortly after I bought it a couple years ago. I mainly notice the issue after the boat has run for a bit but I have noticed it when it is cold.

The boat will idle a bit rough and rpm's will bounce around a little bit. If you don't know the boat as well as me, it will stall when you slide it into gear. I can keep it from stalling when I am driving. If it stalls, it will fire right back up. I do not notice any performance issues when up at skiing speed. Also if it is idling roughly and I am in the water getting ready to ski, I notice a bit of a rich smell to the exhaust..

Since I have owned the boat, I replaced the low pressure fuel pump 2 years ago. Then before the start of the season, I did a full tuneup that included plugs, wires, cap, rotor, oil change, thermostat and impeller.

I was researching and it seems that it could be a sensor or two, but couldn't find anyone with the exact symptoms that I am experiencing. I know a few of the sensors aren't expensive but wanted to try to get a little guidance before I order anything.

I appreciate everyone's help and advice in advance.

Thank you,
AJ
