I have used non genium parts and oil for petrol v6 petrol engine since owning a boat, i dont do OEm stuff unless i have no choice, the Engine oil from RK will be the same spec as the stuff you buy from an auto store with the same spec. Im trying to get an alternator for my V/P 434 v6 rk want £350 ringing around the same alternator i can get for £200, or a USA Delco inport from Repower marine in falmouth is £125 deliverd to my door.
