i have a 1150 mercury outboard 115 hp when you first try to start it doesnt want to start unless you use either i dont like the ideal of useing either because its hard on stuff and has no lubrication but once you get it start it seems to run fine once you shut it off for a little bit you have to crank on it and squeeze the primer bulb to get it to start back up was wondering if the fuel pump good cause this or not
