3 problems dont know if they are related. First for about a month or so an alarm sounds at the helm every minute or so when idling or low rpms and sometimes when cruising. The sheet says its a low oil alarm but the level is good. Removed the sensor from the tank it looks good but do not know how to test it. I did not see a float. Also the engine starts fine but need to still choke it after drivingn for about 10 minutes then its ok or it will stall if i don't choke it. Newest problem happened twice this weekend boat would not plain out or go over 3000 rpms . Only happen those 2 times then it was ok. Haven't tried it since. Thanks
