I'm going to replace the carb on my 1987 8hp Mercury with a new carb ment for a 15hp. I've done my home work, I know that it will fit and I know that it will make the motor gain 7hp.<br /><br />My question is,<br />How much should I expect to pay for a new carb? Also, can I put it in myself?, I'm not stupid and can figure out normally stuff on my motors, but I'm by far no means an expert.<br /><br />Thanks,<br />Ryan
