This topic has been debated at length on these forums as well as others sites.All to date vro equipped John/Rudes will run just fine on 50:1 premix if the vro is bypassed by disconnecting and plugging/capping the oil feed to the vro pump and disabling the vro alarms.However ,if the original vro pump is not in good operating condition ,it will need to be rebuilt or replaced with a conventional style fuel pump to perform as a 50:1 pumper.This post is not advocating that you should or should not bypass the vro and mix 50:1 ,but rather to inform any members inquiring on the subject that it can and has been done by many and and works just fine.Anyone seeking the specifics on the procedure can perform a search on the Johnson/Evinrude engine forums.
