The motor will run at idle good when I play with the throttle under the hood but when i drop it in forward and I go to full throttle it will only get up to 10-15 mph. I just got it fixed in michigan and I am in Cincinnati. It has been sitting for approx 28 yrs. The lower unit has been redone and the carbs were rebuilt last July. The gas is the same from last july but still smells good. Any ideas on what to check? Could the gas be the problem if it still runs at high rpm when at idle and I move throttle?
