    Ok you knowlegeable boat and boat motor owners, Bubba and I want to post a few questions here and see who can come up with the most complete answers.

    We won't ask why you think what you do, or where you got the information. When we feel we have the most or best answers, we'll post our answers or just say, ya'll done good. Then on with another question.

    This ain't no damned chat room, so keep the bs to yourselves. We just want a complete answer as best you can do. Some of you may be surprised at what you read here.

    We'll get into explanations of answers later, if anyone wants to know how come it's that way.

    First question is in the next post:roll_eyes:

    List everything you know of that creates, controls or limits the heat in a 2 stroke outboard powerhead.



    Sounds like it could be an easy answer to this one.

    Fuel,spark, and combustion creates the heat.
    Thermostat controls the heat.
    Water pump limits the heat.

    Short, sweet, and simple.......
    Let me know if i'm close.... LOL

    You got some of it. No need to add the exhaust valves, ain't none in a 2 stroke; Exhaust ports:roll_eyes:

    C'mon folks, ya'll ask us questions all the time. Now we ask you and we get one response in a half hour.

    Hey Bubba, seems like a one way street here.:confused2:

    Well, I'd be happy to answer if I had a clue.. Just got my first boat late last year and still learning...

    Your one way street is mucho appreciated btw, I read alot in your threads, just nothing to add so I dont post there much :embarassed:

    Okay, I know I'm ignorant. Does it loose any heat by air?

    creates the heat:
    fire from burning fuel
    friction from moving parts

    controls or limits the heat
    fuel/oil mix
    thermostat
    water pump
    water
    air flow
    don't know of any heat sinks but I am sure the electronics have some

    The fuel flowing in a 2-stroke is a major source of heat control.

    And no, I didn't have to look that up... :tounge_out:

    you all are missing spark plugs the heat range is how much heat it disperses

    That so far, is the most complete answer, but you need to add what Dafin posted. Yes spark plugs play a big part in controlling the heat in the cyl head.

    Now we can go on to discuss and question how these things do what they do and for what limitations.

    Hey Bubba, not bad for a first question, huh?

    What, out of the previous post would anyone like to know about, or is it enough to say they do what they do and no one cares how?

    Now's the chance for the ones who claim to know very little.

    Not going to page 2 yet. But I'd guess water flow thru the engine controls the heat. combustion makes the heat.

    Bob, fill us in. As I've told you before, I'm not the most mechanically inclined person I know. It never hurts to learn though. With a little thought, I can envision what the parts are doing. I may not understand exactly what they are doing or how but I can rationalize the principles.

    A little knowledge is a dangerous thing.....:big_smile: :cool2:

    Assuming the outboard is working properly:

    Creates:
    Spark
    Spark plug heat range
    Friction
    Compression and combustion

    Controls or limits:
    Amount of fuel getting to the combustion chamber
    Fuel/oil ratio
    water pump
    thermostat
    exhaust and intake

    In the case of an air cooled two stroke, I would say the surface area of the block contributes to its cooling.

    Timing could both create and/or control heat. I would also add that fuel delivery (ie. fuel getting to all cylinders) could have the same effect, but I'm assuming the outboard is working properly...

    I am smart enough to not even begin showing my ignorance. LOL
