    1992 Evinrude 150hp EXEN will not run correctly

    just got a call from Bill with Mastertech, a rebuild kit is on the way, he has no idea what happened, slipped thru some how, but he is making it right, can't ask for anything more....

    I'll get it dialed in. I need to find the time to get the correct O-ring seeing how mastertech will not respond. Thought I would a quality part for what he charges... shame on me...

    1992 Evinrude 150hp EXEN will not run correctly

    Well, I received the new conversion pump system from Master Tech last week. I put it in and it ran fine, I thought, till I ran out fuel, like real fast. Apparently the O-ring that seals the forward pump plastic cover fuel inlet was the wrong size by about 1/4" in diameter to big so the cap never...

    HMMMMmm. if fuel restriction can cause the buzzer and SLOW then I'll check that tomorrow. Kinda makes sense seeing how it only happens over 3500 rpm where it's wanting more fuel... Thanks dwco5051

    1992 Evinrude 150hp EXEN will not run correctly

    it has to be something simple. I'm prusing thru my service manual now looking for something I may have missed... There has to be something that sets it off over 3800 and then reset. I used my IR temp gun and each side stays at around 125-130. I might put the old power pack in and see it that...

    1992 Evinrude 150hp EXEN will not run correctly

    put the boat in. Fired right up, ran rough at idle, I can deal with that. Motored out about 1/2 mile to open water where I can WOT. The motor ran mint at 4000 rpm which is as fast as I really feel comfortable going as it was low tide, after 1/2 mile the buzzer went off and it went into SLOW mode...

    1992 Evinrude 150hp EXEN will not run correctly

    10-4.... I had pulled it the other day to make sure the plunger button on the bottom of it was not stuck, seemed to work freely but that is not to say the switch itself went south.... I don't want to permanently bypass it either, if it is bad it will be replaced...

    1992 Evinrude 150hp EXEN will not run correctly

    I have a new optic sensor and power pack installed. I put those in last week. I'm thinking racerone might be correct with the neutral switch. If I get a chance I'll check that today or tomorrow...

    1992 Evinrude 150hp EXEN will not run correctly

    "Check that shift switch again" If it were a bad switch would it fire on only 3 at all rpms? not just over 1500? "-I suspect spark was lost on 3 cylinders" It purrs under about 1500rpm but anything over that and it's firing on 3 only so there must have been something let loose and put into SLOW...

    1992 Evinrude 150hp EXEN will not run correctly

    I could get up to 5000 but did not feel the need as the tide was low and didn't want to hit an oyster bed at that speed if you know what I mean.. It would scream when I first got it a few months back

    1992 Evinrude 150hp EXEN will not run correctly

    Back in the game, kinda... took the boat out yesterday afternoon after installing the high speed jets, Thank You Racerone, put the boat in, fired up, ran smooth, backed out of the 50 yard long chute, put it in forward and started going towards a 5million +$ yacht with no steering, the steering...

    1992 Evinrude 150hp EXEN will not run correctly

    the VRO was taken out so I premix 50:1 so no chance of fouling or burning up a cylinder due to no oil... the plugs are burning as they should.

    1992 Evinrude 150hp EXEN will not run correctly

    it all started with it not wanting to start but ran pretty good once it started up. Found out the plug gap was at 0.45 - 0.40 not the 0.30 so I fixed that problem. Then I noticed the carbs leaking because the old bowls were warped so I bought 6 new ones and replaced them but had no idea about...
