Listed here is a USED Mercury lower unit from a 2003 90hp 3 cylinder 2 stroke. Its model number is 90ELPTO. It was used on a bass boat on a freshwater Orlando lake its entire life. Engine power head failed so I'm selling the gear case. The drive shaft measures in at approx. 22 1/2" from the top of the vent plate to the end of the drive shaft. Prop shaft has 15 splines and the drive shaft has 13 splines. these were used on many of the two stroke modes from the 1990s up to about 2006 (depending on where your engine was on the assembly line). Lower unit will work on a variety of horsepowers Mercury just changes the gear ratio slightly. This can be adjusted with a reprop if need by. Over all it is in great shape for a gearcase of its age. Gear oil looks clear but can be changed if requested. Impeller should be performed but it was working upon disassembly (Jan 2026). If you have any questions or need help with compatibility please feel free to contact me and I will help you to the best of my abilities. TRADES ALWAYS CONSIDERED. Thank you for your interest. show contact info
