    1983 Yamaha Mariner thermostat question

    we do not even list a 1982 Yamaha so it will be very hard for anyone here to say if it can or cannot

    Loud warning tone when at idle speed

    OK this should be a T60LB if the OP gave the proper info. being a 4 stroke motor it has oil pressure sensors. from what I have read in the past if the oil pressure gets out of the RPM/oil pressure range the ecu is programed to have, either too low or too high it can sound an alarm. some...

    Need good compression, good spark at the proper time, and check fuel rail pressure and then injector operation. test what you can

    F115 IAC not receiving signal from ECU?

    I do not think the temp of the valve should be that hot. from what I have read in the past if the valve sticks and the ecu keeps trying to make it move it heats up and eventually over heats the ECU circuit that drives it causing that to fail also. this is a stepper motor so it is not going to...

    Loud warning tone when at idle speed

    so what does this mean? WOT for 7 miles, (20 minutes) then abrupt slow idle, but alarm doesn't come on. does the motor drop RPM by itself?

    Loud warning tone when at idle speed

    your title on this thread says you have a loud warning tone at idle. now you say "Pees fine at idle. WOT for 7 miles, (20 minutes) then abrupt slow idle, but alarm doesn't come on," I am confused on what you are saying also. does the alarm sound or not?

    2001 Yamaha 50hp tlrz 2 stroke with prime start system starts and dies

    changing out the fuel tank and line should have been simple to eliminate those, by just hooking up a known working one without you having to buy new ones . If that did not correct the problem, look at other things. does not sound like they did much testing just replaced a bunch of parts but...

    Loud warning tone when at idle speed

    that is not what you started out saying When I'm at idle speed, sometimes I get a loud warning tone. 20ft Sunchaser with 60hp Yamaha. Motor isn't overheating - I still have peeing and runs nomally at speed.

    2001 Yamaha 50hp tlrz 2 stroke with prime start system starts and dies

    Very disappointing that they could not pinpoint what the problem was. in those 30 minuets did they run it in gear with a load on the motor/prop? I would be trying it out a lot sooner to see if they actually fixed it.

    2005 Yamaha F115 won't run above idle.

    check to make sure the VST if full of fuel, and if the pump in VST is running when it should be

    Yamaha 130 v4 idle mix screws

    that is news to me also. I believe the idle air jet and fuel jets are not adjustable. the screws allow you to adjust how much of that combination to let thru

    Does this sound like a bad head gasket?

    I am not sure which crankcase the fuel pump gets its pulses from, but as Raceron said check to see if it has leaking diaphragm

    Does this sound like a bad head gasket?

    so it went from fouling plugs to just fouling #2 plug now?

    Yamaha 130 hp oil pump rod adjustment

    check your service manual to see what it says. the manual for a 1999 40-50 says to open the throttle plates completly and adjust to 1mm away from the stop pin

    MPH not showing on Gage OX66 motor

    on my C40TLRX it comes out of the lower unit and runs up the front of the leg and over the T&T upper pin where it heads to the front of motor where it should be easy to see where it hooks into a small hose heading to the gauge wherever you have that mounted. if yours is something electrical...

    MPH not showing on Gage OX66 motor

    sounds like the hole in lower unit plugged up or you have a broken or plugged tubing leaving the motor heading to gauge. disconnect to tubing leaving the motor and blow into it with your mouth to see if the gauge responds do not use compressed air,it can be too much and mess up the gauge

    2000 Yamaha 150 hp runs fine then sputters at dock.

    if it did not run right after the work was done to it, you need to have them fix it right. if it ran fine at all PM after the carb work, but does not now, it means something got messed up . sounds like the pilot jet passages have a problem if it will not run at low RPM or one or more cylinders...

    2000 Yamaha F100 four stroke oil alarm goes off at first and then goes away

    a different prop or a small kicker motor for trolling might be the answer. do they make things you can drop over into water to slow down the trolling speed( kind of like a drift sock maybe)
