    Long or short shaft

    What works for you running a larger heavier boat with a large 115 HP motor at your particular leg's height setting doesn't work for me while runing large sibs/ribs with usual medium light (L) 18-30-40, 2 stroke maxed propped motors sitting on the back. Let's leave it there. Merry Christmas...

    Engine won't reach max RPM under load

    Timing on these mechanical motors factory adjusted don't change whatsoever, unless being factory delivered badly adjusted which has happened several times, an example is the posted 40C motor pic, boaters fiddling with the carb/time advance synch and boaters buying second hand motors in which...

    Engine won't reach max RPM under load

    Let the OP decide that, will need to go that route the sooner or later if wanting his horse to run top and agile. If the tank, the internal mesh filter and the carb's fuel filter are impeccable clean now with a new fuel hose and fuel pump do the following : remove the fuel filter's hose that...

    New (Out of Box) BF20D Over Heating

    Why did you assumed the motor overheated ? the block was very hot as to let your hand touch it for a very short time? Start the motor in a tall bucket and poke up-/down several times in a row the red plastic cannula found in WD-40, carb cleaners cans the deepest will go inside the peeing...

    NS18E2 factory timing info

    Much better is to troubleshoot spark issues with a spark tester, the ones you can increased/decreased the electrode's gap, will tell how healthy or not the Ignition Coil is. If the carb, exciter coil and CD are in excellent shape when having strange rpm behaviors throughout the throttle range...

    Evi 2 stroke 2 HP Motor.-

    Thanks Racerone and Faztbullet.... So max head screws torque is 9.0 NM and max connecting rod torque is 7.5 NM. Being a tiny motor no wonder having such small torque specs. Happy Boating

    NS18E2 factory timing info

    Thanks Tjgatorland, With respect to spark plug intensity, which spark tester was used, the one with a light bulb ? If so, that's not that accurate, measure the spark again at a dark garage and check if bettered. Achieving sparks at both plugs end is no indication that the motor will run top...

    Honda BF15 15HP outboard dies at full throttle

    Was the motor run with a special test prop in a deep water tank at full throttle in forward gear ? If the hose was the cukprit get a new fuel line and test the combo at open water at full throttle and check if misses or not. Happy Boating

    Long or short shaft

    Only a wot run as stated will indicate where is the water flow paasing at plane that's under the upper small plate or over the AV plate. Both plate settings will dial different water performances, being the first one the best overall permormer in all water conditions with modern Tohatsu motors...

    Long or short shaft

    If plan going for a Tohatsu 20 HP short shaft motor, need to check if powers the boat efficiently. Trim it to 90 deg, with deck load well distributed go for a wot run, once on plane, pull your head side of transom and check at which lower leg's plate is the hardened water flow paasing by...

    Fouled Crankcase.-

    There's too many issues associated to this notor : Runs low to medium throttle range - Powers a large medium light boat - Prop has not been maximized, surely revving way under the min lugging wot rpm factory stated when transporting many boaters to their respective anchored boats - The motor is...

    Fouled Crankcase.-

    In previous 2 strokes, 2 cylinder18 HP motors restorations have always found the upper piston to have carboned up more than the lower one and that issue seems to happen in many non Tohatsu motor brands. The posted pic seems corresponds to a 3 cylinder motor, if so, not valid for comparison...
