How many cc is my engine

[RayGilliland]

I have a 100hp Yamaha four stroke engine on my RIB and a friend asked me what size the engine was - i.e. how many cc. I have no idea and have been unable to find anything on the internet to tell me. Anyone know?

It will depend on bit on which exact model it is, as the Yamaha 100 4-stroke has been around for a good few years now with a few blocks I think. A quick Google and any Yamaha specification seems to tell you the displacement and the stroke/bore? E.g.: https://global.yamaha-motor.com/busi...0-75/spec.html or https://www.bhg-marine.co.uk/yamaha-...ard-5650-p.asp .

As per the above reply, a quick Google will tell you. That link suggests your Yam is a 1.8 liter engine. Fun fact: The Honda 150 used to be (might still be) the same 2 liter block that went in the Honda Civic.
