    1997 - 200 Merc : Replaced Rectifier/Volt Reg but Tach still runs high?

    I had an over voltage confition running 16V+ on the Volt Meter. Replaced both Rectifiers/Voltage Regulators but still get a highy running tach - she seems to be about 2000 RPM too high. Also, my trim indicator is stuck in the full-up position, but I think that may be unrelated and need a new...

    200 HP Merc - Intermitent Power Tilt

    I have a 1997 200 HP Merc Saltwater - the hydraulic power tilt has been running a little slow and now it operates intermitently. Yesterday it worked fine - today it is stone cold when activated by the tilt switch on the throttle control and the up/down button on the engine. Seems like an open...

    Mercury Oil or other Brand?

    I run a 1997 200 HP Merc Saltwater - Carburated motor and have been using Merc oil. This oil now costs me $25/gallon when buying from a dealer who sells it out of a 55 gallon drum. My friend runs Penzoil in his motor for a lower cost. Is it worth the extra bucks to continue to run Merc Oil or...

I have been told to clean the yellow wires on the...

    200 HP EFI - Frozen - Any idea on how water got in?

    I have a 200 HP, 2000 EFI that is frozem / siezed. In October 2005 I broke a scupper and the boat laid over on it's side - still tied to the dock only the side of the engine touched the salt water - but I guess some got in. Whe the boat was pulled the enjine would not start due to no spark...

    Partially Submerged -2003 Yamaha 225-4 Stroke

    I am looking at a Hurrican Katrina boat that has a 2003 Yamaha 225 HP-four stroke. The boat took on waves that washed over the back of the boat. I have no idea if the engine was submerged or partially submerged. After sitting for 3 months the flywheel can be turned by hand. I am going to try...
