    98 J115ELECM Buzzer Problems

    Buzzer is going off with key on, not strong signal and still goes off strong at system check startup. I'm sure it's a short, but not sure where to start. Also, is it possible that it's a bad buzzer?

    Timing adjustment 1986 70 HP Johnson

    How do you keep the timing advanced but back the throttle adjustment off? The engine runs great in the water, idles around 1000 rpm. However, the idle is pretty high, 1400 rpm at idle on the earmuffs in the driveway. All the adjustments got out of whack when I replaced the lower unit. Long...

    1998 115 Johnson Intermittent RPM Loss

    Well, true to form, fix one thing, then something else pops up. I went out Friday, got up to speed at around 5000 rpm and a sudden loss of about 2 grand, then bounced back up to full speed. I started thinking about it, got my son to pump the squeeze bulb and she ran fine. I assumed since my son...

    1998 115 Johnson Overheat Buzzer Question

    In another thread I asked about getting the "no oil" light and buzzer to shut off. I believe I've successfully done that. However, in checking to see if the overheat buzzer will go off if the motor gets hot, I can't get the buzzer to sound. I tried grounding both sensors individually from the...

    Disconnected VRO Unit No Oil Light and Buzzer Issues

    On the advice of a couple of buddies, I disconnected the VRO on my 1998 115 Johnson. I took the boat out over the weekend and after running a few minutes, the buzzer sounds for 10-15 seconds and the no oil light comes on. I can live with the light coming on, but is there a way to keep the...

    Stiff steering

    I've got a 115 hp Johnson with stiff steering issues. I took the steering cable out and cleaned the cable and the inside of the tilt tube and the helm and steering cable move freely, so I believe I've isolated it to the steering tube. I pumped grease into the tube until the red grease I used...

    1998 115 Johnson J115ELECM Wiring at the Remote Control

    I recently purchased a scooter with a 1998 115 hp Johnson. Problem is, the wiring at the remote is somewhat jury rigged. The tach got hardwired into what appears to be the main harness and the overheat buzzer pigtail is plugged in but seems to be out of the loop. I've got a repair manual on...

    1986 70 hp Johnson no spark

    I let my motor sit for a while (several years), went back through it and overhauled the carbs. Took it out and it ran great, but on the way in, started missing as if it was running out of gas. I assumed the pickup in the new fuel tank was set a bit high and starved it for gas. I got it home and...

    Testing Temperature Sensor

    How do I test my temp sensor? I pulled it from the cylinder head and plan to heat some water to 180 degrees and see if it sets it off. Do I need to have the lead "wired" to the cylinder head? I know the buzzer works by grounding the connection, I just want to see if it will go off if I get the...

    Water Pump and Thermostat Question

    I have an '86 70 hp Johnson with a pre-79 lower unit. I put in a water pump kit for an 86 Johnson but used a pre-79 impellor. The only difference I can see in the kits is that the upper "cup" where the impellor sits is one piece on the newer model wheras the older model is a split ring, 2 piece...

    85 hp Yamaha clogged water flow

    I posted about this motor on "spark plug blow out" a few days ago. This is a 3 cylinder, 1990 model 85 hp motor. We've since determined that water flow may be inhibited between the powerhead and the exhaust ports due to salt and corrosion. Outside of pulling the powerhead, is there any way to...

    Spark plug blown out

    90 model 85 Hp Yamaha 3 cylinder. My buddy was running at around 5200 rpm, everything going good until, bam! Sparkplug blows out. He took the cylinder head off, and everything looks clean, but the upper cylinder part of the head has some hairline cracks. It doesn't appear that the piston came...

    Hi, a friend of mine just got a boat with an 85 yammy on it. The serial # is CV85ETLD, the number below it reads 688 L 412495. Any help is appreciated. <br />Thanks in advance.

    Another Dripping Johnson

    My gearcase is leaking out the back end. It is definitely gear oil. It appears to be the rear seal (prop shaft). I don't think the shaft is bent as there is no undo vibration while running. Is this something a backyard mechanic can repair, or should I bring in the pros? I have the manual, but it...

    86 70 Johnson (ex VRO) intermittent hard start

    I bought this motor a month or so ago. Replaced water pump (full kit), fuel pump, all new fuel lines, cleaned all carbs, did a de-carb on the engine. Only ignition work was to install new spark plugs. It's been running fine, actually, it still does. However, yesterday after drifting a bit, I...

    70 horse Johnson cooling system modification service bulletin

    Thanks Bubbakat for the SB. I installed the water outlet fitting at the top of the exhaust cover which makes more sense to me as the location for the tell-tale water outlet. When I ran the motor, I had a big increase in water pressure (10 lbs at idle). I still had the flow restrictor in the end...

    Leaky Gear Case or Unburned Fuel?

    I've got blue fluid at the skeg (I'm using Quicksilver Premium Gear Lube) in front of the prop. How can I easily determine if this is gear lube and not unburned fuel? I know that a test is to pressure up the case and see if it holds, I just don't have the stuff to do that. The gearcase oil at...
