I was talking to a dealer the other day about this subject... I was told that depending on the year of the boat that there is a disc shaped indentation in the rear of the boat near the engine to glue a through hull transducer...

Just got a new Challenger with he 255 HP engine. The owners manual states to use 91 octane. Every station in the area sells 87, 89 and 93, no 91. Are other folks using 93 or mixing 89 and 93 for 91. I'm guessing a little higher on the octane won't hurt anything, but since this engine is already pushing a lot of HP, did not want to run it any hotter than necessary. Look forward to your thoughts.

93 octane will work just fine and wont hurt anything... Just make sure you're using ethanol free gas...
