Which side is Cat A

[DAI]

It’s been one of those summers.  Popped a SPN:65675 FMI:11 code today and I’m guessing time for new O2 sensors.  Which side of the engine would be A?

Bank a is the 1 3 5 7 side

So right side if you are looking from back of boat forward on a v drive.

Awesome.  Thank you.

Are pre-cat and post-cat 4-wire O2 sensors the same sensor?  I accidentally ordered a 6-wire from Bakes (should have checked the engine first) and both are 4 wire.  Since I have the MP engine, I was going to order the non-Raptor Indmar 4 wire.

All four of the O2 sensors should be the same on your engine.  The Indmar four wire narrow band heated Lambda O2 sensor should work, but the six wire wide band sensor used for pre-cat on the raptor engines will not work.

Perfect.  Thank you.
