Hello all, new to forum and e-tec motors. I just bought a 2009 E115DSLSEF outboard and want to change the spark plugs. I have heard that I need to index these plugs. I dont see index spacers on any of the old plugs but do see an allen head set screw on side of spark plug hole. Is this how you are able to index these in the cylinder? Also where is the electrode supposed to point? Or does my engine not require this??? Sorry I was a Yamaha guy for decades and have done all my own service and maintenance but these are new to me and I don't want to screw up anything before service manual gets here but I want to use boat tomorrow and need to change the plugs. Thanks for any ***istance!
