    Bad hesitation at 1200 rpm

    Hey guys, my 2005 3.0 tks has a bad hesitation at 1200rpm only. It idles smooth and will run on plane all day long but just that one spot in the rpm range it falls on its face. Not that it should be related but I recently had to pull the engine to replace the starter and flywheel. New plugs...

    Water tank fittings

    Hey guys, could anyone tell me the correct way to install male threaded fittings into a water tank? Would I use thread tape, o-rings or anything else for that matter? I tried asking the guys at westmarine but no one had an answer for me. Thanks!

    Can’t get outdrive fully seated

    I have the outdrive on with another inch to go but cannot get it to budge. I pulled it off about a dozen times now and everything looks good. I’m in gear, shift linkage all lined up, everything greased. What am I missing here? shaft should be well into the coupler at this point, right?

    New cdm-now won’t rev up

    So my 06 90 elpto carb suddenly started running very poorly last week. Came to the conclusion it had a bad cdm part 827509-a8. Mercury said its superseded by part 827509a10. Put the new cdm in and it started up and idled great, but now won’t rev past 5k, almost as if theres 5k rev limiter. I’ve...

    At what temp should an overheat alarm sound?

    I was running my 90 2stroke today at cruise speeds and the alarm went off. My temp gauge was showing around 135 degrees. Tell tale stream was relatively cool to the touch. Cylinder head was pretty warm but I don’t think I’d call it hot. I don’t think I was over heating, but I do believe the...

    Mercury 2stroke plugs surface gap vs standard?

    Hey, does anyone know if there would be clearance issues running a standard electrode plug in a 90hp elpto? I’ve had a few people swear that these 2strokes will idle & run better, especially at lower speeds over a surface gap plug. Is anyone here running standard type plugs?

    Merc 90 rough just above idle

    Hey guys, my ‘06 90 elpto 2stroke idles well, but gets rough with vibration just over idle rpms and then clears up over 2k. At 3k+rpms this thing runs superb(as well as my 4 stroke). Any ideas what could be causing this low speed roughness? Plugs, fuel pump new & carbs cleaned. My carb...

    Is there a general lifespan of reed valves?

    Hey guys, going through my ‘06 90 elpto- carb clean & gaskets, new fuel lines, plugs, filters, etc.. was wondering if reed valves are something to be inspected? Mine, I’m sure are the original stainless. I have no reason to believe they’re bad..Do these have some kind of lifespan associated...

    Mercury 90 loose lower cowling

    Hey guys, the the lower cowling assembly on my 90 elpto has a ton of play in it. I’ve located the bolts that hold the halves together and they’re tight but I cannot find where or how this thing is actually mounted. I see no other bolts or nuts anywhere that would tighten this up and take the...

    anyone been able to get their 3cyl 2stroke to actually idle good?

    If so, what did you do? My 2006 90 elpto idles like something from the 70's. I know they're not the smoothest motors out there, but I've read some people swear they were able to smooth it out by adjusting carbs, using synthetic oil etc.. Ive drained my oil & filled my oil with Amsoil Hp...

    Mercury 90 vs E-tec 90?

    hey guys, recently bought an 18' bowlder with an '06 Merc 2stroke elpto. I found a nice low hour E-tec 90 still under warranty i'm considering. The dealer is willing to take my outboard in on trade. He's telling me the E-tec will outperform my Merc even though they're both 90 hp and that fuel...
