"Hello.
We had a 9HP Yanmar 1GM10 fitted into a 13' clinker launch a few years ago replacing a Stuart Turner 4HP petrol engine.
I was surprised to see that the boatbuilder kept the original stuart propeller, and suspect this may have a lot to do with the slow speeds we're getting from the boat. I would be very grateful for any advice on a change of propeller that could be better matched, or any propellers you know work well with this engine in a similar size boat?
Thanks
Ben"
