I recentyl bought above motor but am trying to rebuild the trim. Apparrently the trim unit was only aftermarket in 81 but standard in the early 70's. it is a Prestolite single cylinder. I am only trying to find out what oil to use in the ram at this stage. Cant find any info on the net and other tilt units i found had different types of oil and no consensus amongst responses on oil type. can anyone pls help
