You need a tachometer and tell us the rotation per minute (rpm) number on the tach with the throttle wide open....as fast as it will go. I assume you aren't going as fast as you think a 50 hp should push you. On getting 50 hp out of your engine, that only occurs when the rpm get in the center of the recommended max operating range.....like 5000 rpm on some engines.

I checked the battery it shows 12.50 volt when motor was off and after starting motor and putting on speed. Checking 15.25 and maintaining or increasing a little, noticed my 2 wire which was connected with rectifire was cut because of corrosion, cleaned, solded, and taped it and its good.

Thanks for your help guys
