Sea King 7hp oil mix and type

[JOK]

I have a 1973 sea king K700 3107A, serial # 920301, type no 60 27370R.

I understand that the oil mixture is 48:1. Do I user chain saw oil or outboard oil? Leqaded or unleaded gas? Is this motor air or water cooled? How much oil to 6 gal tank for 48:1 ratio

Re: Sea King 7hp oil mix and type

My aftermarket manual specifically requests TCW rated oil.
TCW3 is fine.48:1 is something like 2.8 ozs par gallon.16.8ozs per 6 gallons.
17ozs is close enough for easy measuring.Your power head is air cooled with a water cooled exhaust leg with an impeller.Unleaded 87 octane is fine.
