Customer Reviews

Always goes!!! Review by Manuel

No problems so far, always starts. Use this on a racing yacht and it gets some abuse, but can't fault it. Good technical knowledge from Force 4 too, was going to buy another brand but the chap I spoke to really knew his stuff. Delivery was quick and all I had to do was put the oil in. Wasn't 100% sure what I was doing so gave them a ring and they talked me through it, done and ready in 2 minutes. Thanks guys.

very good product Review by Dad

I mainly use the outboard for powering my tender and for an alternative power source for my 16ft Wayfarer.
This outboard is very light, reliable and fuel efficient.
The quality of the product is high and I have not yet had any problems with it throughout the 3 years I have used it for.
