On water hose 170deg im pretty sure

If I were you with the closest Merc service 3 hrs away, I would definitely buy a Rinda Scan Tool.
At this point its all guess work and a scan could pinpoint the problem. |

Don't get me wrong it runs great fires up first turn of the key. It just runs rich the back of the boat has a kinda grease film after being out and plugs look to be running rich.
So......you need to do some CSI work. WAG don't wok well even on stock motors. Less so on those that have had non OE changes made. |

^^^ what SB said , if your running all the same stuff from the super charged engine, it should have a custom tune in the ECM and larger injectors, is it a mefi 2 or 3

Wait, SWAG-Scientific Wild Azz Guess

Its mefi 2

IMO, you may have multiple things to address, sooner or later its going to foul the plugs so bad that they wont refire, I would find someone you can trust and send them the ecm and see whats in it, or put up with it for the summer and do it later, but with out scanning it you don't know if its sensor related or not, such as a map

Mefi 2 is what I have
