    2006 Mercury 9.9 HP outboard - 4 stroke

    it's hard to say till you look at it, it could be a needle value for the bowl that is not sealing and causing the bowl to overfill etc i'm sure most rebuild kit should have all gaskets and orings that you need in the pack, just shop around and check?

    yup thanks, I plan to get hold of fuel tank and lines, if it starts and runs for 5-10 seconds, then step 2, check LU, renew oil, impeller, pull flywheel and replace or recondition stator, then try to run it with earmuffs, if it still works, then will look at renewing or replacing wirings, then...

    quick update, I made some new battery cables to ensure a good ground because I tried cranking it last and it won't crank thought the solenoid went bad, but new cables sorted it out, and bonus now there is strong spark 6-8mm easily on both coil I'm pretty confident the engine will start now with...

    if you reckon the gasket is not correctly in place that would be the first place to check, if you got time, may as well restore the carby, should be plenty of kits for this, not exactly hard job, plenty of youtube videos, many reasons why carby leaking, try fixing the gasket first, if not, just...

    ic was referring to the switch box (332-4911A 8) yea i got the values, they range from 0.15-0.2 depending on the output of the alternator, so it's not something I could measure with my meter yup, will try to check out the stator tomorrow, but now I'm baffled at lack of spark, as there is only...

    yup thanks, i'll check the mercury switch last as that's the least important for now, probably easiest way is unscrew it and aligator clip the terminals to a multimeter? would I need to connect a check valve for the fuel tank or that could be skipped for now? just tested the stator, red blue...

    ic, so makes sense the mercury switch is still a very important safety feature as mentioned a few times now I do not intend to use this engine but also do not intend to bury it in landfill if it still works 2) my setup got electric tilt trim, that should be safe 3) checked the fuel lines...

    2) I thought the purpose of the mercury switch is when the engine tips over it cuts out engine? What's that got to do with reverse? 3) the diagram seems to agree the top goes to fuel filter and bottom to fuel lines of fuel tank? 4) I checked earlier and definately this is the linkage to the...

    honestly I know f all, that's why I'm here hahaha just took off the lower unit and it's shifting and spinning fine with minimal effort, but there's a small chunk of black thing near the water outlet which most likely was part of an impeller, will do the compression test tomorrow but as I said...

    found the service manual, all makes sense now 1) is the yellow cable 2) mercury tilt stop switch 3) that looks like the fuel pump, connects to fuel tank and fuel filter, strange to have to route the hose to there, maybe there was a hose missing 4) pretty sure this is throttle linkage 5) will...

    would almost certainly fully agree, I wouldn't be taking it out to the sea, but if I could get it running half reliably, some kid may want a cheap engine to cruise around in the river or lake

    hi everybody, I need some help please... just got this engine from a boat project trying to work out if this will start tried to do a compression test, but it's very hard to turn with the compression tester, and I noticed the prop will always turn even in neutral and I cannot find a spot where...
