Morning luis...on the original 9.9's (1974) that's all ya do is replace the carb. Later versions also had shims placed on the reeds and a tuned exhaust pipe for the 15's. I don't think the 15 carb for your year is available anymore from Bombardier. You may have to hunt around for one. Maybe one of he other guys on the forum can point ya in the right direction.<br /><br />OBJim
