Yes, but, if the schedule had been adhered to, the plugs would have been changed at the 1st annual service, which would have been within the warranty period (or did early Optis have only a 1 year warranty?).

Can I borrow your tool box?

Would love to but my mate was knocking my door down for Opti oil, spark plugs, air filters, and fuel filters when I sold my boat.

Little did I know I was gonna buy another Opti and then eventually a Verado!!
