Update: Confirming that the interference (ringing) in all speakers (8 cabin, 4 tower) went away once the tower volume control knob (located in glovebox) was disconnected. Hope this helps others!

I feel like a kid at an adult conversation and the joke buzzed right past me here… 

so seriously, unless the first set of plugs is under what I thought were coil packs, I don’t see both sets.  So the first ones are directly vertical on the top of engine more or less.  Sound right?

Well yeah, the port side ones… right?

Welcome to the crew!

You cannot go wrong with either boat.  The 247 is going to be amazing for the days when you have more people.

Proper voltage is needed for many of the engine electrical systems to function properly, including the Universal Exhaust Gas-Oxygen sensors.  The condition of the batteries, charging system, and the cable connections on the battery terminals, battery switch, alternator, power distribution post, and engine block ground can all affect system voltage.
