A 2.5 HP single cylinder OHV 4-stroke engine, with 4.15 cu. in. displacement, generates plenty of power for small tenders and inflatables. It features easy-to-pull recoil starting with Suzuki Pointless Electronic Ignition. No battery is required for this remarkably simple and reliable system. All Suzuki engines come with a 5 year Warranty. We will also PDI the engine for you before dispatch at no extra charge!
