  1. Re: engine stalls when steering wheel is fully turned to either side

    I would pull the drive and retest. Don't forget to feed it water while testing. Inspect the Gimbal bearing and joints while apart.
  2. Re: 2006 Horizon 8.1 exhaust manifold lifespan

    Elbows are stainless.... When the Manifolds are 8-10 years old I change them.
  3. Re: 2006 Horizon 8.1 exhaust manifold lifespan

    The Mercruiser 8.1 is not available in a full cooling system. If the Iron manifolds are 13 years old I would change them. Cheaper to replace the manifolds then to replace the long block.
  4. Re: 2006 90 hp DFI Mercury Optimax idle problem

  5. Re: 2004 BF25 Very hard cold start, wont idle

    Problem is you cannot remove the mixture screws and the some of the passages on the body are the size of human hair. The only time I had success is hot tanking them in a high-end ultrasonic cleaner...

  8. Re: 2004 BF25 Very hard cold start, wont idle

    Plus the intake gasket.....LOL
  9. Re: 2004 BF25 Very hard cold start, wont idle

    I service a fleet of these smaller Honda OBs (BF30's)for a local Yacht club..... I replace the carbs as a complete assembly when they need work. Problem solved.

    Re: 4.5L 200hp winterizing

    Jeff,

    If you are not sure how to do this, pay a pro to do it for you. Replacing a 4.5 engine will be very expensive. The exhaust manifolds alone are $$$.

    Is your engine Fresh water cooled or...
  11. Re: Starter not engaging - Mercruiser Direct Drive ski boat

    You are hearing a click but it is not your starter.....Find and replace the slave solenoid.
  12. Re: 2006 90 hp DFI Mercury Optimax idle problem

    Re: Johnson System Check

    If it is going through the sequence while the engine is running, the gauge is bad or you have a loose connection.
  15. Re: 203 Mercury 125 Saltvwater-oil in carbs and fuel line

    Change the pulse check valve on the engine. You cannot clean it, just replace it. This check valve pressurizes the reserve oil tank and lets the pressure out when the engine is shut down. If the tank...

    FYI, The boat hull does not dictate what engine you have.

    Mercruiser does not go by model year. Their engines are in Serial Number groupings.

    If you have it, you should post your engine serial...
