    DF140 possible blown head gasket. Corrosion issues.

    Small follow-up… recap- the lower unit on this engine is experiencing severe corrosion in a freshwater lake. I pulled some of the anodes today and while the transom bracket one and the lower unit one are pretty bad, the three I pulled from the engine are not so bad. Based on the condition of the...

    DF140 possible blown head gasket. Corrosion issues.

    I got an eye on the head to block area and it does appear to be, I’ll say “overlapped” or “keyed-in” rather than a head slapped on a block. Do I have to remove the powerhead as a whole before I can split the head from the block? Thanks!!

    DF140 possible blown head gasket. Corrosion issues.

    2004 DF140 on 2002 19’ Larson in fresh water. Not sure about hours. This engine has been in the family since new but left my care for many years. It came back to me and I have spent the summer getting it running better. Found cleaning corrosion in the VST, cleaning the injectors, draining fuel...

    DF140 surging

    Update- I made a slick little fuel psi tester from a 1/4” npt brass tee, two 5/16” barb fittings and some longer lengths of 5/16” fuel injection hose. I put a 0-60 gauge on it and it sat in the space at the top of the fuel rail where that little air box usually lives. I ran the boat and it...

    Fresh water corrosion and anode choices…

    Even tho I might look lame in the anode department, I do change lower unit lube every season. Thank you and I will be watching for water in the gear case. I looked after this engine for about 5 years when we first bought it and then it went to my in-laws and a local marina. After 10 years, now...

    Fresh water corrosion and anode choices…

    Thanks all for the insightful responses. I have not checked our slip for stray voltage but do think I should shift to magnesium anodes. I am not finding direct-fit magnesium choices for our Suzuki DF140 but I am seeing generic parts. Can I or should I bolt magnesium blocks on top of new stock...

    Fresh water corrosion and anode choices…

    Hmm. Not really shore power but our neighbor about 40 feet away has a fully powered boathouse in the water with a fridge, lights, ice eater power and that kind of stuff. Doesn’t seem like that stuff would leak to water. Any way to check for stray juice like that?

    Fresh water corrosion and anode choices…

    Oh yes, sorry I got that backwards. I was thinking it might be acid rain over the years. The Lake must be fighting that pretty well to be basic. Thanks…

    Fresh water corrosion and anode choices…

    So is that a water/exhaust passage and not connected to the inner gear case?

    Fresh water corrosion and anode choices…

    Our 2004 DF140 has corrosion attacking the lower unit. We just recently discovered this hole with water draining out when the engine is tilted. We’re on Lake George in NY and the water while being drinking quality may be slightly acidic. Edit- just read ph ranges between 7.5-8. I recently read...

    Suzuki 2011 DF150 Overheat issue

    I am chasing an overheat alarm but haven’t done my impeller yet. I did find this tho which is bad like the OP jrozycki… This water came squirting out when I trimmed up out of the water. Can someone speak to how bad this is? If it’s just a water jacket, I also was thinking JB Weld. I saw a gear...

    In-water testing for overheat. How hot is too hot on your hand?

    My wife and I have taken over a 2002, 19’ Larson with a 2004 DF140. Been in the family since new but went to the other side for a few years and hasn’t been cared for and serviced. Sank once. Bad gas cap. Never had a pump impeller replaced. Pisser missing. Tach is not working. Water psi gauge...

    DF140 surging

    ‘04 DF140 in the family since new. Engine starts and idles well. At full throttle, generally down on RPMs but running fairly smoothly. Tach has stopped working so can’t report revs. No codes. Occasionally will “come to” and increase RPMs and take off. Then back to somewhat less RPMs. Definitely...

    DF140 Tach/Monitor tach not working

    2004 DF140. The four lights and beeper come on and turn off at key-on. After that, I get a momentary blink of the REV light which I assume is part of the ENGINE HOURS code. I get no movement of the tach needle at key-on or when running. I read here the single yellow (not the 4-pin) is the tach...

    What is this pinched tube and broken tee?

    If you look below and to the right of the oil filter, you can see the broken tee. If you follow the run on that tee, it’s harder to see the flat spot. The tubing was smashed in the cowling halves and permanently molded flat. It’s the water pressure line and specifically the water pressure “kit”...

    What is this pinched tube and broken tee?

    2004 Suzuki DF140. I removed the stb side lower cover and found a broken tee and a small tube pinched completely flat. One branch goes into the bundle with the controls and wiring headed forward. The other branch goes to a crankcase fitting. It seems like the breather circuit. Can anyone speak...

    115 Yamaha Tachometer - Other functions?

    owner of a 2016 Yamaha 4-stroke on a Bennington pontoon. Tach does not work. I will be checking connectors and found a wiring diagram here for signal and power. The seller said he would replace if the gauge is bad. Can anyone tell me if the tach has other diagnostics or features I would want to...

    Stern Light Socket

    Thanks again, you’re right. No wires to be found. I thought they may be in that tube but when I took it apart, I saw a hole drilled through the bottom of the top rail. If I would have looked, I would have seen that without removing the station base. That station base is machined (little u shaped...
