    Mercury 1995 115 runs well until below 1000 RPM

    The only thing I could think of would be that the charging coils in the stator are shorted, so this could impact the stator's performance in creating electricity to power the CDMs or ignition coils. Disconnecting the yellow wires from the voltage regulator would eliminate that issue but now you...

    Does the switch box impact the rev limiter?

    When mine was running, before I replaced the stator, voltage on the battery was around 14.4 volts and the motor ran fine until you got below 1200 RPM. Eventually it wouldn't start even when cold. I've replaced the stator and switch box and the battery is still charging at the same 14.4 volts. I...

    Mercury 1995 115 runs well until below 1000 RPM

    There's another thread I started, regarding the switch box and rev limiter https://forums.iboats.com/threads/does-the-switch-box-impact-the-rev-limiter.765529/ It also has references to this same problem I've been having. After I replaced the stator and switch box I could run up to 5000 RPM and...

    Mercury 1995 115 runs well until below 1000 RPM

    Well the stator creates the voltage for the spark and to charge the battery. It sounds like the stator to me. CDI switch box is about $35, stator is $249 and Mercury says to replace both if either is bad. If the motor is firing okay when it runs I'd say the trigger is fine and it doesn't damage...

    Mercury 1995 115 runs well until below 1000 RPM

    I wouldn't think that the yellow wires would be the problem. I thought those were for charging the battery. Does it always run okay until you turn it off? Does it start okay when it's cold but not warm/hot? Those were my symptoms and it turned out to be the stator. I'm in the process of making a...

    Does the switch box impact the rev limiter?

    Hi Mark :) I was wondering when you'd find me over here. I've been watching that thread as well as this one. I posted in 3 forums I believe, but got responses in just 2. You and I are in agreement on disconnecting the rev limiter, just waiting for the holiday to be over to prove us right...

    Does the switch box impact the rev limiter?

    I totally agree but it's cutting out exactly at 5000. I never had the problem with the OEM switch box and this rev limiter (new in 5/2020). When I replaced the stator and switch box last week I was able to start and run the motor up to 4800 for several miles with no problem. I just can't go full...

    Does the switch box impact the rev limiter?

    I agree, but I tried measuring the resistance between the red wire and the base, old and new stators, but there was none. There may have been too much paint on the metal and I didn't want to scratch it in case I need to return it. Without the limiter I'm thinking it will run like before, up to...

    Does the switch box impact the rev limiter?

    It doesn't require the rev limiter. I have disconnected the black/yellow wire from the switch box for the limiter and will test next week after the crowds go home from the lakes. Yes I do have a factory service manual, but there are errors in it. For example: If you have the stator removed in...

    Does the switch box impact the rev limiter?

    It is a separate component, but my motor has one. I've already replaced it once. It stacks on top of the temp sensor alarm, right/port side of the motor.

    Does the switch box impact the rev limiter?

    Okay, Chris. I can head to the lake next week. The limiter is supposed to be set to operate at 5250, which is just above the normal 5200 for my motor. I think the CDI switch box is affecting this somehow. I will head there next week and report back. Everything that floats will be on the water...

    Does the switch box impact the rev limiter?

    Newer fuel line/bulb 3 years ago, fuel pump rebuilt a few weeks ago with no debris inside it, new fuel filter on port side last fall, new small fuel filter on starboard side 2 weeks ago. No problems at WOT 5200 RPM last fall except the motor would shut down below 1200 rpm and not restart until...

    Does the switch box impact the rev limiter?

    I just installed a new CDI brand stator and switch box on my 1995 Mercury 115. The engine now starts and runs very well. I'm happy with that. However, it now seems to be hitting the rev limiter at 5,000 RPM. With the old switch box I never experienced that. I'm pretty sure it's the rev limiter...

    Mercury 1995 115 runs well until below 1000 RPM

    My 1995 Mercury 115 started having problems last fall. After a long run to the marina when we got into no wake and I slowed to 1200 RPM it was putting along fine. I dropped to 1000 RPM and it immediately died and refused to start. (Died like the kill switch was pulled or key was shut off.) I...

    Can a faulty voltage regulator cause intermittant drop outs?

    This is for a 1995 Mercury 2-stroke 115 HP. The OEM regulator was failing maybe 8 or 9 years ago and was replaced by a Mercury mechanic at that time. Voltage reading is up to 14 volts but normally around 13.8 when charging. Starting in fall last year I experienced a "bump" when up on plane at 40...

    1995 Mercury 115 bumps and chirps

    My 95 Merc 115 has been a good motor but it started acting up in the cold (43F) water yesterday. I was out on Tuesday, running up to 20-30 mph with no troubles. Took it out yesterday, Thursday, and started having problems. I made a run of about 5 minutes full throttle, got to a spot and started...

    1995 Merc 115 slowly loosing power

    My 1995 Mercury 115 performed well for many years and really isn't performing too badly right now. It seems to be losing power. When new, it would get to 53 mph but the last few years it's dropped to 48 and now 45. It starts ok but will flood easily if you're not careful. The hole shot is...

    What to use on interior fiberglass hull after removing transducer

    I am in the process of replacing the GPS / Fish Finder on my Ranger R72 boat. The old transducer was mounted to shoot through the hull and was quite large (old model Bottomline Sidefinder). I am in the process of removing it and the epoxy it was mounted in. When I'm done there will be some...

    Replacement fuel gauge died too

    1995 Merc 115 and Ranger R72 boat. Last year the fuel gauge quit registering any fuel. I took the boat in for something else and had them replace the gauge. I checked it when I got home and the new gauge was showing fuel; that was last fall. I went out to the boat yesterday, still sitting in...
