Mercury FourStroke 3.5MH – 3.5HP Portable Outboard Motor For Sale

The 3.5 HP Mercury Outboard Motor (3.5MH) occupies a rare and practical position in the portable outboard market — one of the only 3.5 HP outboard motors for sale from a major manufacturer available in the United States and internationally. For boaters who find the 2.5MH marginally underpowered for their specific boat and load, but don’t want the additional weight of a 5 HP engine, the 3.5MH delivers a meaningful step up in thrust at just 29 lbs — only 1 lb more than the 2.5MH. This makes it one of the best power-to-weight upgrades available in the portable outboard category.

Mercury’s FourStroke combustion platform on the 3.5MH delivers everything boaters across the country and internationally have come to expect from a Mercury portable engine — clean, quiet 4-stroke operation with no oil premixing, excellent fuel economy at trolling and cruise speeds, and reliable pull-start performance in every climate condition. The 15″ short shaft keeps the 3.5MH compatible with low-transom inflatables, tenders, and dinghies, and the tiller handle provides straightforward throttle and gear control without any installation complexity. Mercury’s corrosion-resistant construction ensures reliable performance in both fresh and saltwater environments.
