    Problem solved!

    I started a couple of threads on here over the past couple of months regarding my Mercury, 2004, 200hp (carb) motor, serial number 0T92238. My problem was, when the motor warmed up, it would lose some power (drop from 5000 rpm, 45 mph down to 4000 rpm, 35 - 40 mph). I checked compression...

    Intake Air Control Valve?

    2004 200hp Mercury (200XL) with carbs (serial # 0T922318) I just read a post on here where someone with similar problem I'm having fixed his problem by cleaning the IAC (Intake Air Valve). I'm trying to determine if my engine (listed above) has this part. I see a Thermal Air Valve listed, but...

    enrichner solenoid?

    Can someone please explain what this part does (enrichner solenoid)? I know it's connected to the fuel line and I'm wondering if it could be causing my problem with the motor "surging" during high speed. When cold, the motor runs GREAT at 5000 rpms and 45 mph. As soon as the motor warms up (a...

    2005 200 hp Merc; Dirty Carb?

    When the motor is cold, it starts fine, idles fine and has plenty of power taking off. While running comfortably at 5000 rpm and 45 mph, after several minutes the motor clearly starts "jumping" (i.e random, quick bursts off power every couple of seconds). Sometimes when this happens I can hear...

    2003 200hp Merc Running Strange

    The motor starts great, runs at low speed fine, when cold, it planes easily and runs smoothly. After a couple minutes on plane, usually around 3500 - 4000 rpms, it starts to have irratic, "jumps" (i.e. very quick losses of speed). The longer it runs, generally, the more frequent the "jumps"...

    Suzuki 175 hp 4 stroke tilt/trim issue

    My motor keeps tilting all the way up. If I dont hold the tilt/trim button in the down position, the motor raises all the way up. This just started today and the boat is in the water so have not been able to look at it yet. Is this probably a relay switch that has gone bad?

    How Much Gear Lube?

    Can anyone tell me how much gear lube goes in the lower unit of a 2003 200 HP Saltwater Merc engine? Do I simply add until lube comes out of the vent hole, then replace the plugs or is that too much lube?

    2003 200 HP Mercury Knocking / Losing Power

    I have a 2003 200 HP Mercury Saltwater motor (not EFI, just the basic motor). While cruising down the river yesterday, about 4000 RPM and 35-40 MPH, I hear a "pop" in the motor (sounds like a small rock was thrown at the motor), and the motor starts to lose some power. It drops to 3000 RPM and...
