It starts and idles fine. It has problems getting to plane when under load. Its struggling when two people are in the boat. However it does it sometimes with just me in the boat, but it eventully gets up to speed and planes fine crusing at about 15-20mph. When two people are in it, it seems like were traveling at 5-8mph. I changed all fuel lines and bypassed quick disconnect because old merc. line was falling apart and getting debris in lines. I changed spark plugs, and diaphram for fuel pump. I even cleaned the carb out and all filters. I changed lower unit gear oil as well. I'm new to outboards and curious what could be happening. I have a 14ft Bass Tracker and don't feel the motor is under powered for the boat. When I first got it, it ran fine until I messed tthe fuel/oil mixture up and it was running rich. When I drained and refilled the tank with the correct mixture, thats when I discovered the bad line. Since then I have had problems. Can anybody please give me anymore advice on what I may be missing? Anything would be greatly apprecciated. Thanks!

Get a tach and make sure you are getting the correct rpm's. Check the prop and make sure you don't have any discarded line wrapped on the shaft. Unless there is absolutely nothing in the boat but you and the gas tank, I seriously doubt you are doing that kind of speed with a 9.9. Make sure you have the correct prop for that 9.9 as well. Have a tohatsu mechanic look at it. I tried to fix my fuel pump as well and ended up putting it on backward!! I have a " slightly modified 9.9" tohatsu as well.

How would you go about putting a tach on it? As far as speed it's only an estimate. The prop on it is probably the stock one, but I have read that there not always the best prop for your application(being your boat, etc...). How did you modify your motor?
