What is the oil /fuel mixture for a 1995 johnson 88. V4 outboard. previous owner used Penzoil synthetic blend.

Question

I just purchased this 2 stroke boat in Denver and owner mixed 32:1. Also what oil does the manual recommend? I understand I should stay with a synthetic oil. is that true? 1995 Glastron GS-16

Answer 1

32:1 is way overoiling.

50:1 is correct.

you can use any TCW-3 certified oil *BUT* don't mix dino with synth or semi-synth in the oil reservoir.

Stick with the champion plugs, too.  QL77JC4 at .030

Answer 2

Ok! the previous owner mush have had reasons for 32:1 and I have no problem with synthetics..... So, ask him why 32:1 as most mechanics will say 50:1......It may have something to do with local knowledge, like the lake is at 5000 ft and the engine has been adjusted for that ALT.    Good Luck !!
