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...
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...
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...
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...
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:
-...
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.

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.

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 -...
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...
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.

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...
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...
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...
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...
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...
