    2001 OX66 stumbles at idle after running wot

    It seems that somehow the linkage from the throttle plate to the oil pump linkage was binding keeping the throttle plates partially open. It was hard to track because it didn’t happen constantly. I found this myself after the shop said it was good to go. Now I have to readjust the oil linkage...

    2001 OX66 stumbles at idle after running wot

    VST and fuel pressure regulator screen was super clean. Not even a speck of dirt. I guess I’ll just take it in next week

    2001 OX66 stumbles at idle after running wot

    The oil pump linkage itself wouldn’t spring back. This was causing over oiling. It effectively held the throttle plates open more than they should be. The idle would occasionally hang at higher rpm’s. Changing the oil pump fixed this. I disassembled the oils pump and sure enough the little...

    2001 OX66 stumbles at idle after running wot

    Fellas I’m so sorry about dropping off the planet for a while. I was in the hospital then we had deaths in the family. Not to mention a good case of Covid. Anyway, this issue still persists. I did get some improvement after cleaning a really dirty fuel pressure regulator screen but that was...

    2001 OX66 stumbles at idle after running wot

    This girl runs great on the top end. Really anything above idle she runs great. However, when I slow down to enter a no wake zone or just to idle while graphing the engine stumbles and occasionally dies. She starts right back up. Also, when I first put the boat in the water it starts right up...

    OX66 loses rpm and speed at wot

    My 2001 OX66 (200hp) runs perfectly. She starts and idles like new. I can even run wot for about 15-30 seconds before it starts gradually slowing down. It will get down to about 53 mph and stay right about there. It just started doing it one day. I run it two to three days per week every day of...

    Stray hose on '96 Mercury 115

    My motor is idling really rough and barely stays running at low speeds (just beyond idle like when putting it on trailer). Sometimeswhen I engage the throttle it dies unless I do it really fast to get past that slowest speed. I have had it in the shop twice and they say everything fine and that...

    96 Mercury 115 2+2 question

    Is it possible to make the 1996 Mercury 2+2 4 cylinder engine to run on all carbs all the time instead of making them all kick in at 1800 rpm? I really hate this design but I picked one up really cheap so I thought "what the heck?" It suddenly dies at full throttle. I just want to change he 2+2...

    Mercury suddenly dies at full throttle?!?

    I have a 1996 Mercury 115 ELPTO that runs perfectly. The problem is that when I am running at full throttle the engine suddenly dies. It doesn't sputter at all. It just dies. Then I can fire it right back up and it will do the same thing again. It does feel like it wants to go faster for the...
