More background info will help. Link to comment Share on other sites More sharing options...

landbased Posted June 12, 2012 Share Posted June 12, 2012 When I had my last outboard this happened to me as well. I discovered trhat the fuel tank I had ( Plastic one) had a valve on the top that let air in as it used the petrol. I loosened this and it stopped stalling out on me and ran beautifully until I sold the boat. (worst descision of my life ((( ) Link to comment Share on other sites More sharing options...

PRED-ATOR Posted June 13, 2012 Share Posted June 13, 2012 mate u might also have dirty or water in your fuel. check the water seperating fuel filter. I also had a formosa 520 centre console but with a larger 75hp merc on it. Also check the spark plugs. another big thing to check is your fly wheel magnet. if your accelerating and it gives bumps and loss in acceleration it could be a crack in your fly wheel magnet. out of interest, how does your boat go with a 40hp? your boat is rated to 90hp 2 stroke Link to comment Share on other sites More sharing options...

Guest Aussie007 Posted June 13, 2012 Share Posted June 13, 2012 when u buy a second hand boat dont use the fuel that is in the tank even if the seller says he just filled up always tip it out and start fresh because u dont know how long the last of the fuel sat in the tank and u dont know if theres any other contaminating shit in there and if u want to test the fuel pump pump the primer untill it goes hard than start the engine and continue to pump the primer if problem solved all good if not remove the fuel hose take both plugs off the hose and hold the hose vertical than turn it around hold it the other way u want to drain all the fuel in the fuel hose now look on the bottom of the carby(s) there will be a single screw on the bottom of each carby undo the screw and let all the fuel drain out than do up the screws reconnect the hose add fresh fuel and u shouldnt have any problems unless the main jets are blocked with shit than u will need to remove the carbies and clean them with carby cleaner and a air compressor Link to comment Share on other sites More sharing options...
