No power steering on that oldie! you probably have a seized steering cable or helm. Remove the cable from the tiller arm on the transom plate, and see if the wheel turns. If it is the cable or helm the steering will still be stiff. Replace the helm and cable as a package. a good replacement...
I have a 1987 mach1 which has a 3.0 liter mercrusier. I am not very familiar with everything on my boat and was wanting to check the fluid on my tilt/trim. I can't locate a resivour anywhere. Any advice?
