4 reviews for Mercury 90hp 20″ Shaft | 90ELPT
+ FREE GIFT
excellent upgrade. this 90hp gives me the performance I needed without overkill. got it for a decent price and it’s proven itself in everyday use
good engine overall. starts easily and handles light chop well. knocked off a star because vibration at higher throttle can be felt a bit, but still dependable
quiet and reliable. throttle response is crisp, and the build feels durable. minimal maintenance so far. a great motor in its class
this Mercury 90 ELPT runs really smooth. great power, solid midrange and good fuel efficiency. the 20″ shaft fits perfectly for my rig. very solid motor
