Hi I am new to boating and I appreciate the help. I bought a used boat and it had the motor described on it. I took it out 6 or 7 times this season with no problems. The next time I went out on the way home it all of a sudden lost about half power, give or take. It still sounded the same, it just didn't go as fast. I took it out again and the whole time it just had about half power. It started up fine and idles fine, as far as I can tell. Anyone know the problem or can steer me in the right direction? Thank you!

I had the same problem on a 1972 50 hp. Check to see if the rods on the carbs that connect then together didn't come loose. Check spark.
