    1989 70 - won't idle in gear

    OK, I have a 1989 Johnson 70 that will not idle in gear for longer than about 30 seconds. It will idle forever in neutral. I have already changed the idle mixture as detailed here: http://forums.iboats.com/showthread.php?t=361234. The mixture change improved things, but it still won't idle...

    OMC 70 TSB 2276 - that never happens!

    So yesterday I went to apply TSB 2276R1 to my 1989 Johnson 70, as detailed here: http://forums.iboats.com/showthread.php?t=222677. I have a very occasional overheat problem, so wanted to bring the motor up to date with all the TSBs. I got my 1/8 NPT tap and drill and was ready to go. It...

    1989 70 - update carbs for better idle?

    I have had a 1989 70 for about a year now, and it does not like to go slow. After you've been running at speed for a while, you can idle in gear for about 1 minute, maybe a bit less, but then it starts to stumble and cuts out. The motor is fine above about 1200 RPM. I've completely rebuilt...

    Lower Unit Eaten Away by SS Jack Plate

    I'm not sure of the best place to post this question, so I'll try here. I'm being told that a jack plate made from stainless steel will cause the lower unit of my outboard to get eaten away very quickly by corrosion. I am not sure if this is a real issue, or an old wives tale. People don't...

    Mounting / electrical ?s - non-VRO pump for 1989 70

    I am replacing the fuel pump on my 1989 70 - the oil line on original VRO2 pump has been capped off for years, and I am suspicious of diaphragm problems, so I have acquired the non-VRO pump, p/n 438559, based on advice from this forum. I have some questions as I start to tear into the job: -...

    Symptoms of reeds not sealing properly?

    What are the symptoms of one or more reeds not sealing properly - is it obvious? I am in the process of rebuilding my carbs, and I'm trying to decide whether it's worth the time to pull the manifold off to check the reeds - they look OK from the carb side. Tim

    1989 70 - cam follower bushing p/n?

    The plastic bushing that covers the throttle cam follower on my 1989 70 is pretty worn. I can't seem to find it in the exploded parts diagram - can anyone help with a part number? Anything else needed to replace it? Thanks. Tim

    "Extra" water pump gasket - 1989 70

    The water pump kit I got for my 1989 70 contains a gasket whose outline is the exact same shape as the bottom (metal) plate of the pump, and the inside is open. The gasket is not shown on any of the diagrams I have seen, and my factory manual does not mention it. It's a standard paper gasket -...

    Idle Pickup Timing - 1989 70

    I have a 1989 70 triple, early production with the non-adjustable carbs. The OMC manual has 2 different link and sync procedures; apparently there are 2 different throttle cams and there is a separate procedure for each, called "Method A" and "Method B." I have the cam that corresponds to...

    Sierra carb rebuild kits?

    The Sierra carb rebuild kits are about half the price of the OMC ones - have these worked OK for folks, or is this one of those cases where paying for "the real thing" is worth it? This is for a 1989 Johnson 70 if that makes a difference. Thanks. Tim

    Idle Fuel Flow in 1989 70?

    I have a 1989 70 triple, early in the year when the carbs had the fixed idle air bleed. Can someone explain to me the fuel flow at idle? In other words, where is / are the passage(s) that bring fuel in at idle? I know the air comes in through the air bleed, and I can't see that getting...

    Gas back through oil line on 1989 70

    I have a 1989 70, and the previous owner had disconnected the VRO by capping the oil pipe inlet on the outside of the cowling. Yesterday, when I squeezed the primer bulb, I noticed a drip of gas coming from the fuel connection area. After further investigation, it's not coming from the gas...

    Unregulated Power Supply and Maint. Free Battery

    My 1989 70 (and the attached boat) came with a maintenance-free battery. This is clearly not recommended by the manual. However, the battery does seem to be working and holding a charge, and there is no spitting of electrolyte visible on the battery or in the case. My voltmeter does show a...

    1989 70 - Remote Wiring Diagram (in color)?

    Does anyone have a color copy of the wiring diagram for the remote control for a 1989 70? My manual's picture is black and white, and I can't tell what feeds into what in the connector. My warning horn doesn't function when grounding the temp sensor, so my next step is to unplug the remote...

    Intermittent restarting problem with F200TXRD

    My 2004 F200 has had this problem occasionally since new. It crops up maybe 2 or 3 times a season - other than that, the motor has been flawless. The symptoms are that after you've been running for a while, you shut the motor off for a few minutes - say 15 or so. When you go to restart it...

    Adjusting idle mixture w Boyesen reeds

    This is for a Johnson 70, if it matters - the instructions I have seen for installation Boyesens include replacing the orifices to run a bit richer, to prevent the possibility of backfiring. If I remember right, the instructions indicate that even a single backfire could damage the Boyesens...

    1989 70 - orifice service bulletin?

    Some time ago I ran across a post that referred to a service bulletin about a changing the stock orifices - I could be misremembering, but I think it was to avoid a potential lean condition. I know that the one sure way to trash the classic triple is to run lean for any period of time, so if...

    Lifting a 1989 70

    My 1989 70 has what looks like a lifting ring bolted to the crankcase aft of the flywheel. However, the manual talks about using a lift rig that bolts to the flywheel - said rig comes at a price, of course, so I would prefer to use the existing ring if it is adequate. I am concerned that the...

    Why change to adjustable low speed jet?

    While looking into parts compatibility for my Johnson 70, I noticed that OMC switched over to an adjustable low speed jet sometime during 1989. Does anyone have insight into why the changeover? Were the fixed-jet motors not performing satisfactorily? Tim
