Should not be that hard. Tape up the ends so you can hold it with out getting cut, (if its ragged or sharp from damage). should be one nut holding the impeller on. If its to tight to hold try air or electric Impact wrench. If its bad you can tap with a hammer to help in removing the old one. If it turned on the shaft you will need to rent a puller. Repost if you need more help.

not enough info. what Manufacturers and model? is it out of warranty? here are some troubleshooting tools and procedures since labor rates at your local dealer could be up to $100.00 per hour. before you start I have two Goals for you. (1) If you learn everything you can about your engine you will become more confortable and enjoy it more. (2)confirm that your engine is ok now. is the noise your hearing piston related, or is it ignition missfire. the compression check and the ignition output test will help answer that. Tools(1) A compression gauge (2) a spark gap tester.(3) A Clymer service manual for your engine. (you can purchase from your local dealer). I know all these are expensive but if your going to be a outboard owner you will always need them. Troubleshooting (1) check compression. without the Manufacturer I'm giving you a average numbers. Look at your Clymer manual for specifics. all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark output. use a spark gap tester. all cylinders should jump a half inch gap. If all these test prove that the basic operation of the engine are within specification, then we can turn to fuel delivery. unfortunately you didn't give the Manufacturer so I can't give you the troubleshoot procedures for the fuel delivery system. you will need to refer to the manuel. please get Clymer manuel you will apreciate it
