Hi-
Just picked up my first outboard after years of running a few I/O's. It runs great so far, good compression, no noises, idles and accels smooth. I have started to go through basic checks before taking it out for a day on the lake. I pulled the lower end gear case oil cap, engine in vertical position, stuck a piece of wire in the hole to see what the oil level was. It seems low about an inch down from the filler hole. It's been suggested I change the gear oil. Can anybody tell me what the oil capacity is and the procedure, the specs on a 98 Force 120 perhaps?

The nearest marine store is 50 miles from here and they said a shop manual for a 98' Force 120 would take a few days. I can order on online but also takes a few days. Anybody know where I can get a download?
