Re: Question
Rotella-T 30W oil, watch for it on sale at Tractor Supply, the spark plugs are a matter of choice, since they are GM blocks I would assume they have AC Delco's in them. Any auto parts store can look up and order them for u\you and give you the gap.
They should be AC MT44's I think but not positive, also a little googling will find your plugs. MIKE

Re: Question
I'm sure you will get many preferences in regards to oil. I run Mobile 1 in everything I own. 15/50 is what Mobile recommends for the newer GM boat engines.
Thanks
