    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...

    98' SeaDoo Gtx limited with hole in resonator (muffler)

    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. If I start to back the machine in the water it starts to sink very quickly. Is there a guide or can someone help me find a good source on how to fix this problem? Can it...

    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...

    Removing outdrive when not aligned

    Working on a 1982 merc 140 I/o that was making a god awful noise, first thought was it lost a ring. Go to pull the outdrive, mc-1, this thing is not coming off. It's in forward, verified by turning counter c.w. I take a look at the front mount and notice the adjustment nut is none existent, not...

    Merc 120 Hp (3849449) overheating

    I have a merc 120 hp model 3849449 that seems to have a cooling issue. The temp climbs to 180 degrees very quickly, i would guess that it would keep climbing but I haven't wanted to over heat the engine. I figure it's either the impeller, but this test was done on the muffs so my thoughts were...

    Shift cable stuck after outdrive remount

    I replaced all the bellows and shift cable on my MC-1 outdrive, 1968 4cylinder 140HP, and now it seems the shift cable has no movement. The intermediate shift shaft coupling is aligned inside the shift shaft slot and the shift slide assembly was also correctly aligned with roller to the best of...

    Mercruiser 120 Backfire After Rebuild

    Greetings, I'll try to be succinct. Working on a Merc 120 Hp (3849449) thought to be a 1975. When I try to start (it's out of the boat on a pallet) she cranks and wants to fire and then I get a *POP*. The popping noise seems to come from the carb and I even got traces of smoke, guess it could...
