    Thermostat housing hole.

    if that is a 3 cylinder motor then it is not a waste spark system so each plug should fire just once

    Thermostat housing hole.

    some of those inductive tachs have a problem with interference from the other spark plug wires . also sounds like a lean sneeze happening that causes the motor to kick hard and die

    1983 Suzuki DT-60 Outboard Not Running Well

    I would check compression, spark, and timing to make sure it is still in spec. something has changed that should not have without someone moving things. or an idle circuit in carb has plugged up or a vacuum leak somewhere.

    Yamaha 90 tlr not shifting

    can you explain what you meant by no rev?. I thought it meant the motor would not throttle up in RPM never mind I just realized it was no reverse, my mistake. many years ago I came across a shift cable that had slack in the movement of the inner cable. I have no idea how that could happen...

    Yamaha 90 tlr not shifting

    apparently something is coming loose to cause the motor to not shift and operate the throttle as you move the controls. how else could that happen?

    2007 yamaha 50hp loosing power

    since it was a spark problem before, I would monitor spark when problem shows up to see if all 3 plugs are getting spark. if not spark look else where. if it is a spark problem, see what input and out put of CDI is doing. by the way I do not see how loose plug boots would cause that kind of problem

    2007 Yamaha 50hp 2stroke stuck in limp mode

    you need to make sure all 3 cylinders are sparking while problem is happening. inductive timing light attached to the plug wires one at a time will indicate if the spark stays, it will also indicate if the timing is advancing properly and in spec. if that boat has alarms and they work(test...

    G3 analog tach reading high

    I would flip the switches that set the tach for the proper motor it is attached to. could be there is a bad connection in those connections inside the tach. flipping them back and forth may help

    Lack of RPMs Yamaha 40HP 2 Stroke

    seems the other tread states the jet lower will not allow the RPMs to reach 5500 due to the load put on the motor. do you have proof that those 40hp power heads will run 5500 with the jet lower on it? if so post up what you have

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

    prime start system is not a choke. but like you said in normal it should add extra fuel when motor is cold and then close off the extra fuel as the motor warms up. if it will only run properly in the open position, that bypasses the thermal unit and dumps fuel as long as you have the red lever...

    Rodbolt, purpose of the motor mounted neutral switch 1998 Suzuki DT 150

    Can someone tell me what the motor mounted neutral shift switch on a Suzuki 1998 DT150 motor is for? What does it change or effect? The 1997 does not have it and the manual does not have anything in it about it that I have found.

    Rodbolt advice needed on PTT pump filter falling apart

    The trim motor on my 1999 C40TLRX is rusty, so I decided to pull the whole unit to be able to get to the motor easier to clean up and repaint. When I tried to remove the bottom large shaft/bolt that runs through the assembly it would not move so I tapped on it with a brass rod and hammer trying...

    Yamaha C40TLRX main jet sizes

    Well, I just got a new #115 main jet from the Yamaha shop here, that they had to order one for me just to see if I was correct on how to check the orifice size on these Yamaha jets since no one could give me any info on how to check them. I was correct in thinking that someone had drilled out...
