    Looking for pump to drain oil through dipstick tube

    fire the motor up and get it warmed up , shut off, and pump it out. long as you get the tube to the bottom of the pan it will be the same as pulling the drain plug. what do you think will be so heavy that it would settle out into the bottom of the pan and not be able to suck it out?

    sorry, but I do not know much about a Suzuki motor. I have no idea what Suzuki does to limit tilt or even if it does

    normally there is a sticker on the motor somewhere indicaing what plugs should be in it. but a owners or service manual should give the proper information

    is the side pressure you put on it acting as resistance to keep it from turning too easily which in turn causes it to rise instead of just freely turning around maybe

    if moving the motor around affects this, you have a bad connection or wire itself

    2001 DF70 won't go over 3000rpm

    thanks for the update , I do not think anyone could have guessed that was the problem I am sure you will double check things to make sure from now on. and others looking to solve similar problems will need to double check things they did also if they read this post

    Suzuki DT 140 2 stroke carburetor version tilt and trim stuck in down position

    if you have 12V+ heading to the T&T relay when you operate the switches either the relay is bad or you have a bad connection on the Pos or neg somewhere to the relay. have you tried jumping the relay to see if the relay or motor will operate?

    Boat going in reverse but not forward.

    since the OP did not give the motors model number we have no ideaa what it is. but Yamaha switched to a twist to shift in 1995 ,I would have to guess his 80s 40 is a push and pull shift rod. drop the lower unit again and place the lower unit in reverse and the shifter in reverse and hook back...

    1996 15 HP mercury with spark on only one plug

    what are you calling the ignition you want a pic of and what does it have to do with the operation of the trigger? I did finally find this on the CDI electronics trouble shooting web site for mercury's, but not for the 1996 15 hp section. The center hub on the flywheel also contains magnets...

    1996 15 HP mercury with spark on only one plug

    I do not have a pic of the flywheel, but if you read my posts above you will see it is the center ring of the flywheel that the trigger rides next to. the outer ring of the flywheel has 2 magnets and the stator LS and HS charge coils and the lighting coils are what those magnets run by

    1996 15 HP mercury with spark on only one plug

    why would it be sparking on one plug and not the other. there are no magnets passing by the trigger that I can see or detect. I would think it would need 2 magnets 180 deg apart positioned in opposite N S poles to give it the Positive and neg pulses. my question has been and still is , how...

    1996 15 HP mercury with spark on only one plug

    He said he checked the numbers on the original switch box, to order the ones he did troubleshooting info says it should have Pos and Neg pulses out of the trigger that fire different SCRs in the CDI. I am not seeing any neg pulses going to the CDI. swapping the trigger leads into the CDI...

    1996 15 HP mercury with spark on only one plug

    I am down to either the flywheel that gives the trigger the magnetic pulses is bad or the new trigger is bad. this is why I asked how this trigger is supposed to do what it does. and no one can explain how it functions/works, so it is a head scratcher.

    the manual advance moves the trigger coil around to change the timing

    1996 15 HP mercury with spark on only one plug

    done all that testing, but there is nothing written about how to test the pos and neg pulses from the trigger or more importantly how they are made. we did hook up a Simpson 260 to the trigger wires and rotated the flywheel with a drill motor, all I see are pulses in one direction this is...

    1996 15 HP mercury with spark on only one plug

    thanks but that does not help me understand how the one trigger coil is suppose to send out two different pulses (one Neg and one Pos) to the switch box telling when to fire the 2 spark plugs 180 degrees apart on the rotation of the flywheel. as I said the only way we can get the other plug to...
