I am having a power problem with a mercury 115hp 4 stroke. I am told that it is a yamaha with a "black dress". The post by pine island fred entitled '115 overproped', is describing my problem to a T. I am posting my problems under the mercury repair section and am looking for more ideas. I appologize if I am in the wrong section. <br /><br />"The topic by pine island fred has ben moved to the prop post. I respectifully disagree with that movement. they were talking about fixing the problem with a prop conversion, but I think that the real problem in his and my case lies with the engine.
