    Moeller Fuel Sending Unit

    A have a 2007 Crestliner Fish Hawk 1700 which uses a reed switch style Moeller fuel sending unit. Apparently the plastic float on the unit is gas logged! When I place the unit in a clear glass jar of gasoline the float remains at the bottom of the stem of the unit (doesn't float). I do not see...

    Need help.. 9.9 - 2 stroke fuel starved at wot

    I've got a 1999 9.9 2-stroke. I took it out fishing Friday and it ran fine. I took it back out today (Sunday) and as soon as I cleared the dock and gave it full throttle it started to lift the front end then became real sluggish and died. Started it back up and same thing. 1. Checked supply...

    1999 Merc 9.9 sputter/cough at low idle

    My 9.9 ssems to cough or sputter just slightly above low idle. It will idle (in gear) then cough then it seems as though the idle speed drops slightly then picks back up - cough and so on. If I throttle up/down just slightly it will stop. Is it possible that this is the point where the fuel...

    1999 25hp and 9.9 hp impellar replacement

    I'm getting ready to replace the water impellars on both of my OB's. I have a 1999 25 and 9.9 hp 2-stroke mercury. I have the OEM manuals and feel confident in doing this but was curious if there were any "tricks-of-the-trade" that I should be aware of before starting to tear them down? Thank...

    stumble at low idle

    Is it normal for a 2-stroke 9.9 to stumble right above the very lowest idle setting? I can idle just fine at the very lowest idle speed but as I throttle up the motor stumbles briefly (somewhat like a soft backfire) then as I continue to throttle up it's fine. Same thing occurs as you are...

    Good Compression - Low Power???

    I recently purchased a 1999 Merc 9.9 2S. First time out it seemed like the carb need adjustment - it would run fine at wot but when you slowed to just before idle it would idle rough and eventually stall. I took the carb apart and cleaned it out then I placed the motor in a barrel and made...

    1999 9.9 2S compression?

    Does anyone know what the cylinder compression in a 1999 9.9hp 2-stroke motor should be? I have 105psi in both cylinders, is that within specs for this motor?

    9.9 hp 4-stroke rpm range question

    At what rpms do the small (10hp) 4-stroke motors run at? I see in the specs that the hp rating is at WOT RPM's of 5000-6000 but can you actually run a 4-stroke engine at that rpm range for any amount of time without damaging the motor? I realize that the 2-strokes run in high rpm ranges quite...

    Do you own a 9.9hp Mercury?

    I'm trying to get some first hand advise on the performance characteristics of the lower hp 2 stroke Merc compared to the newer 4 stroke Mercs. If you have owned both I sure would appreciate your opinion. My main question is how to they compare at WOT. Is there much difference in top end...

    2 stroke fuel system explanation?

    Can anyone explain to me, step-by-step how the fuel system on a small 2-stroke (25 hp) outboard works. I'm stilling having a problem with a rebuilt motor whereas it runs, in nuetral, for a short period of time and then quits as though you shut off the fuel to it. I thought if I understood the...

    Opinions on MarFab

    I recently tore down my 25hp Merc and found I had scored cylinders that are going to need a rebore. I've talked to Kurt at MarFab recently and he seems like a straight up type of guy. Have any of you used them before and if so, what is your opinion of their work. Thanks

    1999 Merc 25 2 stroke timing question

    I need to tear into and possibly rebuild this motor. I've been reading as much as I can find on the tearing down and reassembling part. The part I do not fully understand yet is the timing issues. Can you use a regular automotive timing light on these OB's and just factor in the 2 for the...
