    2001 Optimax 200 hp Noise at Idle

    I am looking at a deck boat with a 2001 200hp Optimax, 300 hours. There is a predominant squeaking noise at idle, probably the compressor. The link is a short video with the noise. Is some noise normal (as the dealer claims) or is the compressor on the way out? Or is it something else...

    Fluctuating Vacuum Reading on 4-stroke

    Thought I would check the sync of my carbs since my 65 HP 2001 4-stroke Merc was running somewhat poorly. All four vacuum guages on my sync tool were flucuating rapidly from 15-0 at idle cold and same thing at fast idle warm. Checked for any obvious vacuum hose rot, etc. all looks ok. Engine...
