All - I have a 1990 Force 90 outboard - Model # 906X90C. Looking to do a powerhead rebuild. How do I know if I have top guided or bottom guided connecting rods (before I do a tear down)?

They're bottom guided, otherwise you would see thrust-washers around the wrist-pins.
I hope you have the manual
