I just bought an older Whaler, and it has a Honda BF45 hanging on it..

1st question: How can I tell what year the motor is?

2nd question: How much water should the pisser be pissin' at idle?

voluntary question....... ahhh is there an online manual for this motor?

thnx

Go here: Honda Marine - Owners' Resources

If you're just getting this motor and don't know the history then I would replace the impeller for peace of mind. Just my $.02
