    M40C Timing

    That's why always recommend to go for a Hardline Tach/hour model HR-8061-2, check Amazon, costs bit more ($ 28.00) but way to go along best investment ever. The motor will be happy counting with it.... Send the current one back to Amazon, tell them that doesn't work well and trade it for the...

    Suzuki dt9.9 no water at taletale help!

    Was this motor run in salt water before by previous owner way before you bough it ? That's a 40 year oldie. When on muffs if there's water exiting through the prop the pump is working, seems there's a internal blockage somewhere in the water path that carries water out the peeing port. With...

    Which tach brand did you finally got, are the idle readings half or double say from 900-1000 K idle readig. Six wraps is too much, just wrap 4 full turns around middle on any spark plug wire. The tach should read well when set to 2 sparks per revolution, my tachs on my Tohatsu horses are set...

    I use it regularly but not for an overnight soak, 2-3 hours will suffice, clean every fuel passage in the carb body and every orifice in the jets, etc. Clean and micropolish/shine the valve seat with toothpaste and a cottoned wooden stick dampened in water to immaculate clean condition, the...

    I'm open going for a further tech discussion endorsing such motor height installation and the prupose of it with proven tech facts if wanting to go that route, if not will leave it there.... Happy Boating

    Really, with due respect you definitely don't know what you're talking about by simply watching a pic, why would you need to raise the motor for, where do you think that with such setting is the water flow passing by ? give your best wild guess, this is where geographical location and boating...

    Tohatsu 2012 15 Hp Floods

    If the float's needle is not siting and sealing well against the seat valve will see fuel coming out from upper carb but not flooding the cylinders, is that what's happening when you say the motor floods ? Once carb has been stripped to pieces with removed float and needle check with a...

    When priming the fuel bulb with the stamped arrow facing up till firm, is there any fuel pills anywhere inside the motor. There shouldn't be any side effect when the line is connected or not. Maybe Paul has a tech clue as to what's happening to that motor... Happy Boating

    Slow 9.9 Mercury

    That setting it's relative, You will see a drastic speed drop and a back water splash if the water flow at speed bangs against the upper middle leg area... Ideal is for water flow to pass right under the mall upper plate or above the AV plate which it's a matter of personal preference...

    With a standard fuel line and tank with vented cap, the tank is constantly venting small gasoline fumes, with those EPA fuel lines and tank the venting will take place after the tank has released the built in fuel pressure, some say that occurs between 3 to 5 PSI ? Won't releasing small fuel...

    Order a new prop once you know the wot rpm achieved on a water test with current installed prop, not before or worse going for the same prop pitch. Happy Boating

    M40C Timing

    Sorry, missed number 10, good to have all 3 hoses brand new. The fuel pump is suspended by 2 side screws, with a screwdriver check that both screws are screwed fully in till stops, air could be entering there and the fuel pump not sucking fuel right. The motor's posted pic is far away as to...

    By bypass you mean removing the middle air valve at middle hose and installing a fitting there to cancel it ? if so, try it, does the current tank vents by itself or must be operated with the air valve opened if happens to have one installed at middle cap ? Know many boaters complaining about...

    M40C Timing

    A pity that current prop was not tached when new or before was on its way to become spun, won't know if revving at wot as usually loaded to at least middle to max wot rpm range which is ideal, go for a new prop maintaining same brand and pitch or to a less pitch prop to pull wot revs up. Once...

    That EPA fuel hose seems to have flooding issues specially when building too much pressure inside tank. Try out the old tank and connector, if solved the problem saty with such tank. Happy Boating

    Thermostat housing hole.

    So the motor is running much healthier now than before, right ? One less trim hole from 90 degl will make the boat to ride with the bow slight downward which is good as will need to shift less weight up front to plane faster. What happened to the tach, did it finally read true, half or double...

    The neon ones will lie to you depending on your vision state, it's a matter of watching the spark jump intensity and color at a dark place as a garage, put a large towel on yourself and motor and have someone else crank if for you to check the spark. If it's a intense bluish color is good to go...

    You're welcome Marvin, Personally dislike central consoles as well, tiller driving fast response has always been for me. Yep 40's idle bit rough, seems its the spirit of that beast. Nice to count with an induction tach, can install it side of the tiller grip. Which type of decarbonization...

    Welcome back Doug, thought that were long vacationing at Easter Island LOL!! Was the transom height a XL size to match a L shaft motor ? Who chopped the transom down, the horizontal cut looks very uneven. What do you plan doing as not to move the trim setting when solo boating and boating with...

    M40C Timing

    As you have witnessed there's an great timing difference between idle and wot when the gear level has not been put to forward. Some issues : have that motor since brand new or its a second hand one, to know if the timing advance has been messed with. Is it a tiller or remote installation ? Who...
