recommended major service areas
 

friend just purchased a used 2001 Nordic with a 502 f.i. Bravo 1. Meter shows 50 hrs, very clean. Looks like it has been maintained but no records. It runs runs well-no leaks. We pulled valve covers, no sludge, oil looks fresh. Performed a leak down test and all < 18% and compression is good within 5% of each cylinder at 180lbs

Besides a new oil and filter, what would be the minimum "major service' areas to perform on this boat.

Thank you

Replace:
-oil and filter?
-fuel filter?
-plugs?
-check dist cab for arching corrosion?
-flush drive gear oil by pumping in with synthetic bottom up til complete change?
-sea pump blades?
-grease splines on outdrive into coupler?
-inspect all hoses and belts for cracks and replace if nec?


any thing that I missed?

Thanks

anyone?
