    Stiff throttle, and it's not the cables or shifter!

    Airshot suggested that he check the throttle cable while motor is running. He told OP to remove the shift cable before testing, but I think OP overlooked that step.

    Fuel pump diaphram

    I just Googled "1984 35 HP Mercury Outboard" Just slightly over 4,000,000 results. Time to shop!! Not hard to find parts online.

    Can I use this spark tester in cdi?

    What did you set the gap at? 3/8" or even 7/16" is a good indication of a strong spark.

    115 Yamaha overheat alarm at 1,800 - 2,000 RPM's

    My 9 year old granddaughter asked me to take her tubing today. Great fun! I dropped everything to take her and my son out in the boat. Boat ran great, but on 3 occasions while I was running at about 2000 RPM's to go pick her up or just to make it through no wake zones, the overheat alarm went...

    Motor has no power under load

    What problems were you having before the carb adjustment? How is it running? What are your RPMs? When will you be taking back to this mechanic to tell him about the new problem?

    Mercury 50 hp, no power at prop, engine runs fine.

    If you supply the model number of the motor, we can tell you more about the shifting mechanism. Not all motors have a shift shaft that moves up/down, many have a shift shaft that turns. If the shift shaft isn't going up/down, look for the connection from the cable hookup to see if something...

    High compression in 1 cylinder - 7.4 carb

    I'm not an inboard/outboard guy, but that knocking is definitely a valve knock. Either like someone suggested above the rocker stud has worked loose, lifter has gone bad, or for some reason a valve is not opening on that cylinder. I'd certainly remove the valve cover to look for issues before...

    1995 Skeeter ss140 - 135 Mercury Black Max G179207 Constant Alarm

    I can't speak for Mercury outboards, but I've had 2 Yamaha outboards that have had the floats in the oil tanks go bad and cause the alarm to go off indicating low/no oil in tank. On Yamaha, there is a tank on the motor and an auxiliary tank mounted somewhere else that feeds the tank on the...

    Yamaha 50 tlr prime start test

    The only solution I can come up with is like you say take the cowling off, turn prime system on, start and let warm up, turn primer system off (so it doesn't run too rich), put the cowling back on and go. Or, you could run wires to a switch on the console to turn the primer system on and off...

    OEM digital gauges for 1999 115 Yamaha

    I guess I've not been doing a good job keeping the cover on my boat. The gauges have gotten all cloudy and I can't read them any more. They're the OEM 2 round gauge set. Does anyone have a set laying around that they're not using that they would like to sell or trade something for them? I've...

    Bow light not working

    Thanks for backing me up guys. I was the lone ranger there for a while. It could also be a lighted switch wired incorrectly. A switch that has a light that comes on when the switch is turned on basically has 2 circuits and at least 3 wires. Hot, ground and load (power to the light in this...

    Evinrude 150 xp 1990 trim switch blowing fuse.

    Yeah, I was pretty sure that motor had 2 relays. My son recently had to replace the entire system on his 115 Johnson. The sockets for the relays were worn out and became very "iffy" only working sometimes. That first wiring diagram has a mistake. I've always told folks when working with...

    Yamaha 50 tlr prime start test

    I watched that video too. My son has the same motor, but his is a 2003TLRB. the "B" is used on year models where there is a significant change from previous models. That change in 2003 included that priming system. It's a pretty neat concept, but my son just started having problems with cold...

    Stiff throttle, and it's not the cables or shifter!

    You haven't told us what type of motor you have, but most outboards have grease fittings on those moving parts. Obviously, you could start by spraying a bunch of WD-40 all over those parts and linkages and working the controller a few times to let that work into the pivot areas and see if that...

    Boat wont steer right

    Disconnect the cable. Then determine if the problem is with the steering wheel or the foot of the outdrive. Once you know that, you know which one needs some force, penetrating oil and/or some further inspection.

    1980 Evinrude 100HP - Low compression on 2 cylinders. Need help

    You're tagging on to a thread from 2012. You probably need to start a new thread. You lost compression as a result of fixing a lower unit issue?? Did you remove the power head to address this lower unit issue? The gasket that goes between the powerhead and mid section could have been damaged...

    Prop Locking Question (Reverse Locking Cam?)

    Your motor only running on starter fluid is not an ignition problem, it's a carburetor problem. Specifically a lack of fuel to the cylinders. Your neutral start switch might be in the control box. If not, google some information on the motor and I'm sure you'll find answers to most of your...

    Merc 35 horse

    Pretty much every motor out there has the ability to be a good motor. A bit more information is needed. A '65 Mustang was a good car, but if it's been left to rust and it hasn't been maintained very well, then it's garbage today. Same with a used outboard motor.

    Bow light not working

    All a switch does is make contact between the two wires. It basically makes the two wires touch each other.
