    Engine with Solid Tone

    I have twin 200 HP Mercury Off Shore Engines. When I turn my key on for my port engine, it gives off a solid tone before starting it. And when I do start it, solid beep remains. When I turn my key on for the starboard motor, I get the beep, beep, beep and when I start the starboard motor...

    Mercury 200HP OffShore Died

    Have twin 200 engines. Just had props reworked and took boat out for first time in almost a year. Both engines ran great (starboard had a little trouble staying cranked at first) on first leg headed from launch to boat lift (mile). Took it our few hours later and all seemed good from temp...

    Which Prop fits Which Engine?

    Have twin 200hp OffShore Mercury Engines. Just had both props reworked and forgot to mark which prop came off which engine. Does it matter which prop goes back to which motor and if it does, can I ID which prop matches which engine? Thanks for the help.

    1997 Mercury 200HP OffShore Thrust Problem

    Have twin Mercury 200HP OffShores in great condition. Was running about 30 knots and felt a hard jar as if I had possible hit something (and I may have) but never saw it. Powered down and shut both engines off. Checked for physical damage and found nothing. Cranked back up, throttled back up...

    Re-Installing Lower Unit

    I just finished dropping my lower unit on my Mercury 200HP Offshore and replacing the water pump. A local tech told me to put the throttle in forward before I took the unit off. When I replaced water pump and attempted to put the lower unit back on, had issues getting it to line up. After a...

    New Electronic Oil Injection Units - Mercury 200HP Offshore

    For some months, I had a couple of post seeking help for the beep...beep...beep on both my 200HP OffShore Mercury engines. All the great input helped me get to a final determination, take it to a mechanic since I had gone through everything else I was capable of doing. His news was both motors...

    Temp Range on Mercury 200HP OffShore

    Can someone tell me what the ideal temp range is for these engines? I have one that runs at around 150 while the other wants to peg over to 170 at idle. When up and running around 4000 rpm, they both run fairly close at around 140-145, but at idle and upwards to 1200 rpm, the port engine wants...

    Mercury Gear Drive Oil Injection vs. Electronic Oil Injection

    For a month or so, I've been trying to isolate a problem with my 200HP Offshore engines and with the help of you guys, figured out a lot of what was not the problem. Finally got down to taking it to a mechanic and he found that both engines failed due to the gear on the oil injector pump worn...

    Connecting 50:1 External Tank to Mercury

    I know this is probably a simple question, but I have to run my crippled boat about 2-3 miles so I can put it on my trailer for engine repair (oil injector issues). Do I connect an external tank of gas/oil mix line at the motor fuel fitting or do I cut the line coming from the internal tank and...

    Running Oil Injection Engines on 50-1 Mix

    I've been fighting oil injector alarms now for weeks with little resolution on these Mercury Motors. The boat is on a lift and I need to travel some 2-3 miles to a ramp so I can put on the trailer. If I connect my fuel line to a 50-1 external tank mix, is the engine or engines if I decide to...

    200HP Mercury Alarms

    I've been welcomed into the "Mercury" alarm club with both engines blazing "beep...beep...beep". Couple of guys have worked with me on this site to isolate my problem, but I have lost touch in the past couple of days, so I am trying to get an explaination for this aspect of my search. These...

    Straight Answer - Mercury Outboard Alarms

    Talk about the run-a-round. Hopefully, someone out there can give me some straight talk to this issue as I can't find it anywhere else. I have twin 1998 200HP Mercury Offshore (not EFI) motors with roughly 320 hours on the starboard and 345 on the port engine. Few weeks ago coming in from a...
