Thank You Vic.
I finally found an oil-capacity chart online, and yes, at 4.5 liters you are correct (Which is a LOT. I'm used to putting in 2.2 liters in my 60hp yamaha. Definitely a step up in size/class of motor)
And yes, I believe that motor is a Suzuki DF70 with an Evinrude cowl. Good for me! ;-)
I was going to order a manual, but not sure now.
I know the head oil capacity, the type of oil, oil filter number, and the spark plugs. Anything beyond that I will have to deal with at the time.
