I have a 87 Yamaha 50 hp on a 87 Fisher bass boat. The boat at one time did about 40mph but now top speed is only about 35-36. Also when I pull the kids on the tube and turn a sharp corner the engine will sometimes lose allmost all power and I will have to throttle back and start again. the engine starts and idles well and at anyother times runs good.<br />What may cause the above problems.

The first thing you can do is a compression check. You may have a stuck ring. If so, bigger problems are coming.<br />That is where I would start first. All cyld will read the same. If you have one that is low, than that is you problem. <br /><br />Markcv
