    Shift shaft removal for o-ring replacement - 1998 Mercury 25

    Hi, I need to replace the o-rings (Items 35/36) in the attached pic and have to remove the shift shaft in my 1998 Mercury 25 HP Long Shaft to get at them. My question is, how does the shift shaft come out of the lower? I've already removed the water pump housing as I needed to rebuild that as...

    Bent upper shift shaft - easy fix? 1999 40 HP EO

    Hi, My older 1986 35 Merc finally died (splines on crankshaft to driveshaft connection worn) and I'm in the market for a replacement. I found a 1999 Merc 40 EO on Craigslist and went to check it out. Compression was good, it started and idled fine. The lower unit and oil looked good, overall...

    Water pump housing seal install ? - 1986 Mercury 35 HP

    Hi, I'm rebuilding a water pump for an 86 Mercury 35 HP and I had a question on which way the rubber seal and nylon washer (part 27, 28) go in. From the parts schematic (see attached photo) it appears they could would go in the water tube sleeve from the top of the housing. They seem to fit...

    Merc 35 (1986) - lost forward/reverse and pumping water

    Hi, I was out in my boat yesterday and my 1986 35 HP Merc lost forward and reverse gear all of a sudden. It also stopped pumping water. I paddled back to shore and couldn't notice anything obvious. The prop looked ok, so I assume I have to pull the lower. With the motor turned off, if I put it...

    Mecury 9.8 110 - Shifts into gear automatically

    Hi, I just picked up a 1974 Mercury 110 9.8 for my son. It's what I grew up on, so I'm willing to feel some pain of having an old motor for nostalgia purposes. It runs fine, but when you are in neutral, you can hear the RPMs change and it will switch into gear on its own for a few seconds and...

    Mercury 9.8 no water out telltale - blockage

    Hi, I'm having an issue with my 84 Mercury 9.8 outboard where water is not coming out the telltale. My impeller shredded and I think a piece got sucked into the block. I took the pickup tube out and it is clear. I tried blowing compressed air up the tube but barely any is coming out. I then...

    Broken Shift Shaft Assembly - 88 Mercury 35 HP - Long Shaft Outboard - Replacement?

    HI, I lost forward/reverse on my 1988 Mercury 35 HP Long Shaft Outboard (non-tiller). When I pulled the lower unit, the long shift shaft fell out. It looks like it snapped up near the power head as there is still a piece in there. Any idea on the level of effort to replace this? Also, any...

    88 Mercury 35hp outboard - no forward/reverse

    Hi, when pulling up to my dock I attempted to go into reverse and noticed I lost both forward and reverse. I pulled the motor cover and the shift cable and mechanism seem to be moving as they should when I move the console shifter. What would be the best place to start in troubleshooting this...

    Preload Pin Frozen - 1988 Mercury 35 - 2 Cyl.

    Hi, I'm in the process of rebuliding my water pump on my 1988 Mercury 35 HP outboard. I noticed my driveshaft has a preload pin at the top and it appears to be frozen. Can someone explain what that pin does and am I right to assume that should move freely? If it is supposed to move, what...

    Oil in bellows - Mercruiser Alpha One

    Hi, I pulled my outdrive off today and found a decent amount of oil in the bellows which appears to be leaking out of the upper housing. I'm assuming it must be a seal in the upper housing. Any idea what the likely culprit is and how easy is it to fix? Thanks, Ron

    Oil in Lower unit exhaust water - Alpha One 3.0LX

    Two issues: 1-It's snowing like hell and it's October 2- I was winterizing my Mercruiser Alpha One 3.0 and while running on the muffs, I was getting a lot of black smoke and the water coming out of the prop area had oil in it. Any idea what may be going on with #2? I'm guessing it is something...

    help with identifying this adjustment screw - stalls on idle - 1988 mercury 35 HP

    Hi, My 88 35 HP Mercury is stalling on idle and when you put it into gear. Once you get going, it runs fine. I am thinking it may be a timing /idle issue. My Seloc manual is on the way. I was hoping someone could help me identify what the adjustment is for in the picture below. Thanks!

    Hi, Could someone point me in the right direction. I have a 1988 Mercury 35 HP Outboard. The battery was new last season and I kept it on a battery tender all winter. I launched this weekend and the battery keeps running dead. I am wondering if it is a charging issue (rectifier or other)? I...

    Shift/Throttle Cable Adjustment 1988 35HP Mercury - Am I missing something simple?

    Hi, I am having trouble getting my shift cable adjusted properly so reverse engages. Forward and neutral are ok but the cable doesn't extend far enough to fully engage reverse. If I disconnect the cable and move the shift mechanism on the engine, reverse works fine. I have the barrel on the...

    Lower Unit Compatibility - 1988 35 HP replaced with 1986 45 HP

    Hi, I have a 1988 35 HP Mercury long shaft (2 Stroke). The lower housing is damaged and I am shopping for a used replacement. I found a decent one online but wasn't sure on the fit. It is also a long shaft but off a 1986 45 HP. Does anyone know if this is a compatible replacement? Thanks, Ron
