Spark CORRECT WHEN VRO ELIMINATED AND YEAR

[erick11s]

.I just bought a Robalo 25 with two motors evinrude ocean pro 225 each, the two engines have the VRO ELIMINATED and work with pre mix oil with gasoline 50/1, the situation is that a one motor is year 1994 and the other is 1998.

I have two questions-

1: What spark plugs are correct for each engine, for 1994 and 1998 year.

2- The factory recommended spark plugs " Q " are designed to work with Vro.
What is the best spark plugs should be used when working with pre-mix 50/1

Thanks in advance

Erick

Thanks for your comenta but in this link said : In all VRO-equipped motors, the "Q" type plug is recommended (Designated by "Z" in the plug number for NGK)

The oil mixing unit in service mixes the oil with the gas.-------If you mix it yourself it amounts to the same thing.---Never mind what the link says !!
