    200 HP lower unit

    I have a 97 model year (built 96) 200 HP, 2.5liter, 25". My lower is shot. I missed an opportunity yesterday to get a used one that seemed to be in good shape. Owner thought it was early 90's. My Climer indicates the ratio on the 175 and 200 are the same but I don't know what years are...

Please let me know what you think.<br /><br />The owner last ran it this summer when it started making an intermetent knocking sound. He returned the boat to its lift and had a Mercury tech...

    Tilt/Trim

    I have a 82 Johnson 90 on my 17 Whaler. The boat spends part of the time floating in the canal behind my house. This morning I notice we had a very low tide, check on the boat and saw the engine in the water (sure I left it tilted up). The well had quite a bit of red fluid in it (assume trim...
