We take safety at sea very seriously, so you will find many features on our outboards that are there specifically to keep you safe. Every Parsun outboard engine is fitted with a kill cord – USE IT!! you’re an idiot if you don’t. People die every year by not wearing this simple, invaluable safety device. Other invaluable safety features include an automatic reverse lock (the bit that stops the engine from jumping out of the water when you accelerate in reverse), and Start-In-Gear protection (so you can’t start the engine in gear), larger engines have a neutral gear rev limiter so you can’t hurt your engine too! When you buy a Parsun outboard you become part of the family…. and we look after our family.
