Re: VRO on a 1994 70 HP Evinrude?
Depends on how reliable maintence is?
If units are maintaned properly they are extermly reliable if abused they are not.
By maintence I mean check\change oil filter in tank at least once per year (also check low oil warning)
Use good oil XD30 or better
Don't mix oil
Mix gas first tank every year to verify operation. A good time to check no oil warning.
