    Yamaha T50 won't exceed 3500 rpm

    what is the HP rating for the boat? Probably too small of a motor for that size boat , The reason you could not find a performance Bulletin for it with a T50

    Yamaha 130 v4 prop question

    it does not make sense to me. slow to plane out to means too much prop, but that depends on if the RPM comes up fine, but prop is not biting good enough to get the boat moving fast enough. and then it over revs like there is not enough pitch or size to it did you find a boat and motor close...

    Yamaha 130 v4 prop question

    have you looked at Yamaha performance bulletins to see if they had a motor and rig like yours to see what it showed? I thought 6K was above the max on most 2 strokes

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

    did you follow the link and sync procedure in your service manual after you put the carbs back on? all 3 carbs throttle plates need to completely closed and tied together so all are contributing to the idle the same. (not just set at idle position) also the timing is part of the procedure

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

    you have not reported what the timing is doing with the new CDI box installed. at start up my C40TLRX shows around 5 BTDC and idles high. once warmed up it drops back to 7 ATDC. what does yours show? also post up a pic of your new CDI box hooked up. I am not following the problem with the...

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

    there is a chance you have a leak between the pump and fuel tank allowing air to be sucked in,. But then the pump runs off of the #3 crankcase so it just pulses ,so does not run a steady stream. rereading your other post, if pumping the primer bulb helps then look for an air leak between the...

    Yamaha T50 won't exceed 3500 rpm

    Only T50 I found listed was on a 15'7" toon I would not be expecting much on a 20' https://yamahaoutboards.com/outboards/jet-drive-high-thrust/high-thrust/f50-(high-thrust)/pb_god_mighty-g-cruise_t50lb_8-7-2022_pnt

    Yamaha T50 won't exceed 3500 rpm

    a t50 pushing a 20 ft pontoon? not much motor . have you looked at what other people are pushing a boat like yours with? also what prop they used? look at yamaha performance bulitens online to see if they list a T50 for a toon like yours , and if so what prop that used.

    Correct Sparkplug 2000 200hp Saltwaterseries 2 stroke

    was that a Yamaha service manual or an aftermarket one? Boscoe said the Yamaha service manual and owner's manual by the way you mentioned copper ring on some plugs, copper and aluminum do not get along well touching each other

    130 v4 oil tank refilling point

    simple to start draining the tank slowly and see when it refills but I would think your service manual for your motor would tell you about how far it would move to set the switch

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

    sounds like a lean sneeze. and pump is not doing its job if pumping the primer bulb helps. check to make sure pump is still good, and the idle jets/passages are feeding the fuel needed for each cylinder

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

    idle timing is After TDC, ( retarded timing) WOT timing is Before TDC.(advanced timing) guessing at what the timing is actually doing by looking at the none functional wiper does not help at all
