A friend recently purchased a 2020 Excel Catfish Pro 21 with a Suzuki DF150SS and is experiencing low rpm's. Motor has been through the break in period but has never been over 4200 rpm's. The dealer says it is propped correctly with a 23p and really don't know what the issue could be. Is there a rev limiter set from the factory until there is a certain amount of hours on the motor?
