Ok, so my 800 series stringer blew a bearing and cracked the gears. I have what I am told is a stringer 600 outdrive from a 6cyl boat with a good upper gearbox that I can buy very cheap. I am pretty sure the gearbox will fit on my 800, but will the gear ratios, shaft strength, or its overall integrity cause me problems? Any info would be appreciated. Thank You.
