    Yamaha 70B too much Autolube

    I thought all Yamaha's used linkage from the carbs to the oil pump and it was adjustable. threaded rod if it comes off the oil pump goes full on

    Yamaha 200 static flush with boat in water

    I would think someone could rig up something easier to get to. quick connects for garden hoses are readily available at hardware stores if nothing else set a Tee in and bring it out to an area easy to get to and then put a connector on and rig up a cap or plug to close it off when not flushing

    Engine stalls when put in gear

    trash in the air box means mice or something else got in there. no telling what all they could have done. make sure the manifold pressure reading at key on is the same as the local weather station report at that time. change in altitude will affect the fuel to air ratio and power. will...

    2017 F90 cranks but won’t start

    need to know if the rail pressure is in spec. injected motors will not run if there is not enough fuel going thru the injectors

    1999 Yamaha 9.9hp 2 stroke popping sound at WOT

    only popping noise I can think of would be a lean sneeze

    1986 YAMAHA 50HP 2STROKE NO REVERSE STARTS IN FWD!!

    I believe even those old motors were spring loaded into forward. So you have to force them into neutral and reverse. check to make sure you have both the motor and the controls on neutral when r the same gear when putting together

    VIDEO: Runs Perfect For A Minute Then Red Light Comes On, Motor Shutters & Stops.

    yep the red light tells you the motor has a problem and RPM is limited also to help you know to look at the light and shut down the motor as soon as it is safely possible

    General MAP sensor question

    motor not running it should match what your local weather station lists for that time once running there should be more of a vaccum so it should change

    Suzuki DF250S pumping fuel into air intake

    that fuel running everywhere can catch on fire, does not sound like a good way to go. very bad to watch your boat burn as you jump overboard these kind of things is why6 you should sign up for Seatow or other policies. or ask a friend /neighbor to pull you to the ramp. 3 miles is not far

    VIDEO: Runs Perfect For A Minute Then Red Light Comes On, Motor Shutters & Stops.

    well if the alarm is not for low oil pressure then it is probably for overheat or maybe oil pressure out of range

    Suzuki DF250S pumping fuel into air intake

    I have never worked on a DF250 so not much I can say about it, I have no idea where the pump is on your motor just thinking about how injected Yamaha motors are set up with a VST. those are serviceable by taking them apart

    Suzuki DF250S pumping fuel into air intake

    VST is the Vapor separating tank. it houses the high pressure fuel pump that feeds the injector rail

    Bad Spark plugs?

    when you pull/unscrew a plug on a running motor the compression will blow the plug out and probably take some threads out of the head with it as it shoots somewhere never to be seen again. also the coils are not on the plugs, plug wires maybe what you are trying to talk about

    Bad Spark plugs?

    I see no way you can pull the plugs on a running motor I would guess cleaning the injectors or replacing the plugs is what helped

    Suzuki DF250S pumping fuel into air intake

    where is that fuel coming from? if from the VST then the float is not closing off the fuel when the VST is full. extra fuel dumped onto a gas motor floods it, not raising the RPM you have to have fuel and air in the proper ratio to the motor to run properly. adding fuel without adding extra...

    1989 DT115- High idle 'scream' then chugs/quit

    I am not any help on that old Suzuki, just mentioned how some motors advance timing electronicky to increase idle RPM

    Bad Spark plugs?

    Just my opinion, the ones with the tan colored porcelain look like they should, the ones that are still white are not getting proper fuel to burn properly

    1989 DT115- High idle 'scream' then chugs/quit

    some outboards advance the timing at start up and then drop timing back to normal, this causes a fast idle during the warm up. service manual for your motor should give specs for timing, and is easy to check to see what it is with a timing light

    DT200 Power Head Experience - Remove Cylinders?

    I never heard of a outboard that you could pull the cylinders out of the block. have you looked at the parts breakdown to see what it shows?
