That little 6 hp will get you by but, in my opinion, it isn’t really a kicker motor as it really is a small outboard. What’s the difference? The Yamaha T8 and the Merc Pro Kicker are made specifically for that application and both feature electric lift systems, super strong brackets that can handle the pounding, high thrust, low pitch props that provide an incredible amount of thrusts at slow speeds… and electric start. A small outboard will get you by and if the budget was tight I’d run one in a heart beat over not having a kicker at all.
Those Yamaha T8’s are flat out incredible little machines.
