my outboard motor is lagging

[ethan]

My outboard motor is not working out as it should. Water wasn't coming out from the pee hole, so we took it out to the this one guy to fix. He put in a new impeller and now water comes out. But the motor is really lagging. I can't put it in full throttle, and if I do, the motor will sound really loud but the propeller isn't spinning. Does anyone know what the problem is? Is it because the guy who installed it did something wrong? Thanks.

I put up a post but it didnt go through??? Well anyway, S.T. all you guys have helped me out so much!! I'm not pulling any legs here! I just cant seem to solve this problem. I guess it's because I'm very new to all this. This is my very first motor. Ok lets start all over here. This is a 18hp evinrude the year is in between 1960-1970. The 18hp motor is not going fast like it's suppose to, so I put in new spark plugs. A few days later I took it back out to see if that was the problem. Well didn't even get to test it out because there was no water coming out form the pee hole. I then took it back to the guy I bought from and had him replace the impeller. He called me to pick it up. I got there and he told me that he replaced something in the gear, that was fine with me. So I took it back out to see how it would do this time. Well thats when the propeller problem came. It was always spinning just seemed like it wouldn't spin at full throttle. I got some advice from all you guys so I checked out the propeller to see if I can see what you guys are talking about. I took a look at it but could see that there was anything wrong with it, so I opened the gears up and took a look at it to see if there was some that didnt look normal in there. Well I could tell, so I put everything back together. The next day I took it out to see if anything has changed. NOPE! the propeller still acting funny at full throttle,but I notice that the impeller is acting up again now! (Contact US Regarding This Word)!!! Water would shoot out and every other 5 seconds air with some smoke would shoot out,but this was only at lower throttle though. At higher throttle the impeller seems to be doing great. Well S.T. this is the whole thing. I'm not pulling your leg here at all! I know that the motor is good it's just that the lower unit is acting up. To me it doesnt seem to be a big problem, it's just that I dont know anything about outboard motor's. Thanks for all of your help.

Fisher Dave I live in Brooklyn Park. Are you in the Metro area? This is starting to make me give up, but thanks for all you guys replying back with so much info.

leave me a phone number and I will call you. It should not take long to figure out your problem, and probably a solution.. Its raining outside right now so my outdoor chores are getting delayed, I cant use power tools in the rain.. I could look at it immediately.. not worried about money.

ethan I know your not pulling our leg, its getting frustrating not being able to see your rig. Did you drop the lower drive?

Theres a water tube that has to match up into the water pump. At that point theres a rubber seal the water tube slides into. If that water tube didn't go in right and pinched or rolled over that seal it'll not get water like it should.

Back to the cavatation plate is it level with the bottom of the boat. I'm not talking about the prop now I'm talking the horizontal fin above the prop, is it level with the bottom of the boat?

hey fisher dave, sorry for the delay. I havent had time to check my email and get into here for a few days now. However, my brother took it back to the guy who we bought the motor from and is still taking a look at the motor. I hope he can find out the problem. If not I'll give you guys a up date later. Thanks.
