Unmatched in its class, the Tohatsu 9.8 hp 4-stroke has set the standard in portable outboard power! This lightweight motor weighs in at barely over the 80 lb mark and has undeniable characteristics of a true marine champion.

Our 9.8hp outboard is skinny on fuel and big on power while never compromising performance or reliability. It has a ton of features that are usually only found on larger, more expensive outboards. We pack a lot of punch for the buck in this truly unique outboard! In the 10 hp/9.9 hp category, Tohatsu has once again proven itself the leader of the pack with this 9.8 hp 4-stroke.
