    Choke adjustment

    My choke is open when I try to start my boat. Is there any procedure to adjust this? My repair manual doesn't talk about it other than telling me to check the setting.

    Cold start takes 4ever

    I have a '89 4.3 Mercruiser and it takes a long time to start when cold. (A lot of cranking) I replaced the carb because of a bad choke, but it still does the same thing. It runs and starts fine when warm. It seems like it has a hard time sucking the gas from the tank I replaced everything...

    K&N Oil Filter

    I know the 4.3 liter Mercruiser oil filter has a higher oil flow than a normal auto filter. I was reading that K&N has a marine filter called K&N gold they say is better than stock. Is it as good as the Mercruiser oil filter when it comes to flow? I dont really care about filtration much on the...
