hi the question i have is my 07 60 hp bigfoot merc won't go above 3000 rpm's.my dad put a new prop on it on saturday and was getting 5500r's and 20 mph.he then docked it got on it on sunday and it went from 4000rpms down to about 3000-3200 rpms.he switched back to the old prop and it stayed the same.i'm thinking fuel issue but not sure and won't be able to look at boat until saturday.does any one have any ideas or had the same issue.
