    MCM 140 EST Ignition question/diagram

    Gentlemen, I have a MCM 140 #6156174 and it has an EST distributer/coil system on it. I'm not really familiar with these, I am hoping it's gonna make my life easier in the long run, but it looks like I have a little learning curve to conquer first. I'm having an issue getting the wiring...

    Cleaning fuel system

    This is a copy and paste, original poster was Steach from http://www.greenhulk.net/forums/showthread.php?27314-DIY-Fuel-System-Cleaning. I just found it very informative and thought I'd spread his good thinking. If you have an older Seadoo with grey Tempo fuel lines (pre 2001) they need to be...

    Make this a sticky? Mikuni site link here:

    This has all the info you need and since these are the usual suspect I'd say a sticky should be added if someone has the ability to do so....just my opinion. http://www.mikuni.com/fs-carburetor.html

    Bent Drive Shaft, 98' Seadoo GTX

    Gentlemen....I got very slight bend in my drive shaft on a 98 gtx limited 951cc. I was just gonna buy one off of ebay, I just want to make sure I get the right one. The previous owner said they replaced the impeller and I'm guessing they just didn't align it correctly.

    Little Carb Help Please.....98 SeaDoo GTX Limited 951cc

    I can't get this bastard to start and I'm not sure if I have the jets all set correctly. I have the high speed jet screws (the ones underneath that you can't reach once it's all put together) set to all the way in then backed out(c.c.w.) 1/4 turn each. The top (low speed) are backed out(c.c.w)...

    GTX Limited...Lord let the problems end.

    Back to the drawing board:facepalm: Alright gentlemen, I have a 98 and 99 gtx limited. 99' runs like a beast, except, when you first go to give it throttle (I'm talking only on the lake) it bogs and will even die occasionally. However, if you flip the choke lever quickly, while giving it very...

    Odd water in oil question. Merc 140 model 2770087

    Mercruiser 140 i/o model 2770087 (1968-72). Milky oil came pissing out the gasket of the valve cover out on the lake (apparently the valve cover gasket is bad) but I don't understand the milky oil because the dipstick was totally clean, just low obviously. How can this be that the oil in the pan...

    Hi there, I have a 98' SeaDoo GTX Limited that has a hole the size of a half dollar on I believe what is called the resonator.

    Trim up on shifter not working

    I swapped out a gimbal housing from a post 78' to a pre-78', the one I just put on has a linear style trim sender and the broken one had the senders on the side of the gimbal housing by the hinge pin. Since the swap the "bow up" function doesn't work, the "trailer" button does and so does the...

    1999 Sea Doo Bombardier Stuck Choke Issue-(common)

    Hey all I noticed this to be a common problem with Seadoo GT_ models and I thought I'd share it. On the ones I've experience, they will fire right up, but as soon as you go to gun it...it bogs down and sometimes dies. This happen to you? Try this next time: After you are warmed up, grab the...
