    Boat will not get up to speed-gctid750258

    I have a 2011 Bayliner, Bowrider. It ran fine 4 weeks ago. About 2/3 of the drive lube fluid, in the small plastic container mounted just about the alternator, leaked down on the alternator over the past four weeks. I replaced the fluid, and put a temporary fix for the leakage using a small rag. Now it is hard to start, but once started it will easily rev up to 4500 rpm. However, when shifted to neutral, it runs a bit rugged. Then, when shifted into gear, if it runs, it will only get up to about 2500 rpm moving through the water at a slow, slow speed that does not excite the speedometer. Once started, you have to pull the shift back to a really slow idle speed, keep it there for a few seconds, then shift into neutral, then very quickly into forward. Any ideas? Could the oil leakage on the alternator be a problem which may have caused other problems? It has always run GREAT until now! Thanks, river watch

    Did the fluid get on any pulleys or belts? Have you verified that belts are not slipping? If the charging system isn't working, you only get 12v nominal voltage from the battery to run everything, including your ignition. It won't charge and you will eventually have a dead boat. What voltage do you have with engine off ? Engine on? If the voltage does not go up to 14 nominal when you when you are up in the operating range, you likely have a fault in the alternator and are running solely on battery power, which will strand you. You can do a quick test to verify that you are not running on the battery by disconnecting the positive terminal while the engine idles. If it goes off, the alternator is not supplying any power.

      Some of that oil leaked on the shift interrupt switch?

        Battery checks out fine as I started the boat, disconnected the positive terminal, and the motor ran as it did with the positive terminal connected. There was/is no oil on the belts. Any other ideas? Other possibilities? Any idea on how to stop the drive fluid leakage from the small plastic container just above the alternator. Thanks, river watch

          Does the voltage gauge show that you are getting proper voltage when you try to accelerate? It will drop if the charging system is not working right, IIRC. It should rise if it is working properly.

            Two other things not mentioned in the initial conversation which may be important: (1) the boat uses an extraordinary amount of gas (about a half a tank running only a few miles on the river), and (2) sometimes the engine backfires when starting.

              Choke stuck on?

              EDIT: I guess these (if it is a TKS) have an enrichener circuit. Same difference.
