I was reading you earlier post talking about the 1983 115 inline 6 and all the advice you gave that member,
I own and 1984 115 hp in-line 6 in great shape with low hours,i would like some advice please
right now i am using omc tcw 3 because i had an evinrude before at 50-1 is this oil ok? reason is i heard that pennzoil is sometimes used for the merc's , and should i drop down to 40-1 like you advised the other member i usually like to go fast it has a 13 1/4 x 17 prop spinning 5400 rpm tops
also i always put in the 87 octane , i recently put in a trim and tilt and will be testing that tomorrow, i would like to take care of this engine as it runs great thanks
