Just purchased a service manual for my Force 1996 75 hp service manual i received said Force 1996 75hp with starting serial numbers... OE138600 PT#90-831251 995. on manual .Serial # on my motor is OE 186750. But i look at trim tab adjustment page 1-6 and it shows a retaining bolt on top to adjust trim tab , mine is under neath is this because this motor uses a Mercury lower unit. Will the upper part of motor, such as ring"s head gaskets ETC. part # be correct. Thanks
