    SDS connector on Suzuki DF300 with "Fly by wire" Throttle, Shifting, Steering controls

    Helping out my neighbor with his boat.... It has two new(2024) Suzuki DF300s that replaced a pair of aging DF225. The new engine upgrade also included the fly by wire for steering, shifting, throttle, etc. What a great system!!! But here is the question. On the previous DF225 the SDS...

    Mercury Outboard 2017 150 Intermittent Missing

    Just an update..... I have put 16 hours on the Mercury 150 since replacing the coil and the engine has run great. Tennessee weather is cold, so I'm not likely to get more run time till early Spring. As I said above... I'm cautiously optimistic that the problem is resolved by the coil...

    Mercury Outboard 2017 150 Intermittent Missing

    UPDATE: Interesting, I think I may have "hopefully" resolved the issue. After searching the Internet I found a couple of articles that referenced a batch of bad coils that Mercury had used that caused similar intermittent missing. It was the nature of the described symptoms that matched what...

    Mercury 115 HP 4-stroke 2012 Tilt only works with ignition on

    2012 Mercury 115hp 4 stroke. The other day while fishing I noticed that I couldn't tilt up the motor. Couldn't tilt up from switch on throttle or switch on motor itself. The curious thing is that the tilt works when the ignition is on. This is definitely a new issue and I often used the tilt...

    2011 Mercury 4-stroke on a 2012 Tracker. Has run absolutely great since I purchased it used 2 years ago. The other night after leaving a waterfront restaurant it stalled after 5 minutes, couldn't get it restarted. Although this is fuel injected, they symptoms remind me of an old carburetored...

    2012 Mercury 115 4-stroke Where is ECM diagnostic port?

    Just purchased a 2012 Tracker with a Mercury 115hp 4-stroke. I have test equipment to read the ECM diagnostics, but can't seem to locate the diagnostic port/plug. On my Yamaha outboard, the diagnostic plug is visible once the cover is off. Can anyone suggest where the diagnostic port is on a...

    SS collar & spacer on shaft above Yamaha F115 Water Pump

    2007 Yamaha F115 4-stroke I replaced the water pump impeller on this "new to me" motor. I struggled getting the SS collar off the plastic spacer, but through the help of the manual was able to get it off. However, getting the spacer back on the shaft is proving very difficult. If I hadn't taken...

    Intermittent Low Speed operation 2005 Merc 115hp 4-stroke

    I have a 05 Merc 115hp 4-stroke that has a intermittent low speed problem, but seems to be getting worse. At times while motoring along slow, maybe 2000 rpm the engine will begin to run rough. If I take it to 4000 for awhile then back off to 2000 again, it generally runs better for awhile. I...

    Mercury 2+2 Question, what causes it to switch from 4 to 2 cyls?

    I have a 2005 2+2 115hp. It runs great when running on all 4cyls, perfect actually. At times, idling is the problem. Not all times, but about half the time it idles very rough, and smokes a lot. Other times it idles perfectly for long idles into large marinas. I'm wondering that perhaps the...

    Mercury 115 2+2 How smooth should this idle?

    I have a 2005 115hp 2+2 Merc, probably one of the last one's made, just my luck. This motor runs great, but starts & idles poorly. Last year my wife and I put on over 800 miles averaging about 3.5mpg per the GPS on several of the Southern waterways. Above idle, this motor runs great, never a...
