use ringfree or cumbustion chamber cleaner. .3-.6v is good, all else is not.

saw your smoke video...just curious, do you use yamalube for oil?
have you adjusted your oil link rod?

use new gaskets for the O2 sensor housing. part #50, use the superseded part number.

Cousin,
Thanks for chiming in on the subject. And thanks for the helpful links.

Yes, I have only used Yamalube 2M and ring free additive since I purchased the boat used 2 years ago. The biggest problem from my extensive reading of this and other forums is my lack of routine maintenence. I figured hey it runs great and it always fires right up....well, I change the lower unit oil thats all I know how to do that should be good right? No, I haven't adjusted the oil rod.
from what I understand you need to idle the engine for 3 minutes and check you get "xxxx" ml of oil? I have to order the plastic linkage for it also.
I guess I've always figured a mix too rich is a good thing rather than too lean.

Mike

if your ABSOLUTLY POSITIVE your block on a 3.1L has never been changed since mid 02 production then the above part numbers may work.
however in mid 02 the redesigned the blocks and all replacement and production blocks use different gaskets.
cousin, remember to add, RAPIDLY SCALING.
if its sitting like a nut on a log at .3 or .6 it means the output is wrong.
must scale.

Rodbolt,
Is there a way to verify the 3.1 liter engine and vintage with a serial number on the power head?
This morning I placed the order for the o2 gasket, plastic link for the oil pump, high pressure hose clamps and seals for one of the trim rods.
So if I have the wrong gasket I may have other bad parts too?
I have read as many threads about excessive smoking and oil consumption,
what way would you recommend setting the oil pump linkage? Thanks again...Have a good one.

Re: What is the max run-out for 1999 Yamaha 200 HP???

UPDATE: I pulled the o2 sensor off today on a hunch that it would be clogged after reading about some other guys have similar over oiling on their similar vintage engine. Sure enough look at the pics....I spent a around an hour cleaning the housing, tube and sensor. I am going to go out in the morning and run the voltage test. I have a feeling that the sensor will never be clean enough again to operate properly. I tried the combustion chamber cleaner that was recommended by Cousin. This carbon was really tough.

will update later.

Re: What is the max run-out for 1999 Yamaha 200 HP???

For the oil linkage rod adjustment, disconnect the butterfly linkage on the starboard side of the motor, just the bottom set. This will allow the oil linkage road on the port side to seat freely. Use a feeler gauge on the oil pump, I have read .020 and .005. I used .005. on the oil pump, measure between the oil lever and stop. You may have to cut 5 threads off of the linkage rod to screw the plastic collar down enough.

For your O2 sensor cleaning, I use my wire wheel on my bench to remove the bulk of gunk and then soak in Techron, Cumbustion cleaner, RingFree or Seafoam. For the housing, I used a dremel tool with wire wheel to clean out. for the draw tube, I used dremel with a drill bit.

There are cases where the oring behind the oil pump leaks and needs to be replaced.

I would think calling Yamaha Customer support (866) 894-1626 with your serial number, they'll be able to tell what block you definitely have.

Great pics. I think you're on your way to getting that smoking problem under control!

Re: What is the max run-out for 1999 Yamaha 200 HP???

Cousin,
Thanks for the advice on the oil rod adjustment. I actually just completed that. I hope that fixes the over oiling.

I ran the test this morning and got 1.0 and up volts pretty much the whole time. It didn't go down to around .6 volts until I was on the way back to the boat ramp and as soon as I slowed down it went right back up to over 1.0. I am thinking the o2 sensor is bad but I may try cleaning it again. I never ran it over 4k rpms so I don't know if I still have fuel shortage issues at high rpm. I just hate to dump another $300 into an unknown. thanks again guys.

Re: What is the max run-out for 1999 Yamaha 200 HP???

O2 sensor should have RAPID SCALING between .3-.6v
at 1.0v it's probably faulty

The voltage shown on the meter screen will read between 0.3 and 0.6 volts DC with a good sensor and will vary continuously as the computer (ECU) adjusts the mixture. A lower voltage reading indicates a leaner mix and a richer mixture raises the voltage output from the sensor. If the voltage remains near 0.9 volts, the oxygen probe is showing signs of becoming fouled.

Don't run over 4k.

I had to change one of mine after 400hrs.

dang
I am liking cousinabe more and more.
one day I may have to ask him/her if ya need a job.
mcbassin.
you still have the original 3.1L block.
buy your parts by the engine model number.
calling yamaha most likly will be a waste of time.
your O2 sensor pics indicate you have the original style block.

Re: What is the max run-out for 1999 Yamaha 200 HP???

Rod, Thanks for the positive comments. I may take you up on that offer as I recently got back into corporate America and am thinking of a career change!

Thanks, Greg (I'm a he).

Re: What is the max run-out for 1999 Yamaha 200 HP???

Rodbolt,
Finally had time to wrench on my outboard.
I cleaned the o2 sensor again and ran it at the lake yesterday. After the engine warmed up the voltage was .2-.3 consistantly at 3k rpms. Then when I would slow to fast idle it looked like the o2 sensor was working.....scaling rapidly from .4-.7 volts. then as soon as I take off it goes right back to .2-.3 volts. Is this common? Do I need to just order a new one and be done with it? Neither of my volt meters (Fluke high quality) have been calibrated in a few years so I'm wondering if I could be getting an error with the meter?

Re: What is the max run-out for 1999 Yamaha 200 HP???

I read another forum where a guy used a chevy o2 sensor on his Yamaha outboard. Is this a real bad idea? Take a chance on burning up an engine? $70 versus $275 or versus a new power head? check out the link:

Re: What is the max run-out for 1999 Yamaha 200 HP???

anybody out there try an "aftermarket" o2 sensor?

 

[mcbassin]

Re: What is the max run-out for 1999 Yamaha 200 HP???

I replaced the o2 sensor ($250!ouch) back a few months ago and the motor is still running good. Now I am back to the original problem. It seems like there is still a run-out problem. How hard is it to change the prop shaft? What are the special tools that I will need? Would it be best to change the water pump too since I have had it a few years and it hasn't been changed? It still holds 23-25 psi at WOT. squirts lots of water and holds pressure so is mandatory to change the pump every so many hours of use? Does the yamaha parts dealer sell a kit to replace all the gaskets and seals for the pump and prop shaft? thanks,
Mike

Re: What is the max run-out for 1999 Yamaha 200 HP???

max runout is about .002".
however you really cant check it without pulling the propshaft and placing it in V blocks.
lucky for you that unit is fairly simple to get apart.
sounds like your familiar with machines cause you have a dial indicator.
only real special tool you will need is the puller set from BRP/OMC to remove the bearing carrier and a spanner wrench to tighten it on reassembly.
spanner wrench can be made.
I saw one in venezuela made from the front hub of a 4wd toyota .

You know what the part number for this puller? Is this shaft easy to pull? What seals or bearing will "need" changed? thanks

 

[rodbolt]

Re: What is the max run-out for 1999 Yamaha 200 HP???

not real hard.
call any BRP dealer and get the puller legs for the v6 v4 lower units and a standard harmonic balancer puller.
drop the gear case,remove the water pump assy, remove the 3 bolts holding the dhift rod plate, remove the plate,pull out the shift shaft,remove the 2 12 mm headed bolts on the prop shaft bearing carrier ring,remove the ring, remove the 2 10mm hex headed bolts that hold in the carrier.
hook up the puller and pull the carrier. once the carrier is out the propshaft and shift slide assy slips out.
replace all seals and orings removed.
reassembly is pretty much the reverse.
with a fresh water motor you may be able to pull it with some 3/8ths all thread with ends bent in a wide J shape, some nuts and washers and a standard harmonic balancer puller.

Re: What is the max run-out for 1999 Yamaha 200 HP???

Thanks for the reply Rodbolt! It seems like it would be a good idea to go ahead and change the water pump while I've got it apart. You have made it sound like it should be pretty easy.

Re: What is the max run-out for 1999 Yamaha 200 HP???

Mike:

Something you related early on in this thread was that your motor smoked "early in the day" and after fishing a spot for a long time. I wanted to suggest that, early in the day when the sun is low on the horizon, sometimes it can appear that an engine is smoking more than at other times when in actuality, it's simply a matter of perception because the smoke is backlighted. Also, realize that most often when you've been on a spot for a while, you've run at speed to get there beforehand..........makes me wonder if that has more to do with it than the time on station.

I'm not a pro mechanic like some of the great gear gurus on the forum, but thought this might be worth a mention. I'm caught up in your motor's situation and hope you'll keep posting the results - stuff like this is always educational.

Re: What is the max run-out for 1999 Yamaha 200 HP???

Thanks Tony,
Your probably right about the lighting thing. I did notice last weekend at our tourney. Early in the morning you could look around and spot the yamaha engines by their smoke "cloud" around them. And of course the Mercs were the loud ones. Not complaining about the high oil consumption. I did notice after Rodbolt told me how to adjust the oil rod it is a lot better.

 

[mcbassin]

Re: What is the max run-out for 1999 Yamaha 200 HP???

Rodbolt or anyone who doesn't mind helping me,
Well, I never got around to working on my outboard again, but with my fishing season about to get underway I started looking at it again.
I talked to the prop shop yesterday about getting my prop rebuilt and they explained how to find the runout of the shaft real quick and easy, by checking the runout at the centering divot in the end of prop shaft. It seems when I did the first runout check I was checking it on the spline. Well, on the end it is like .025" total, which tells me the shaft almost has to be bent, which is what I was thinking to start with. Anyway, he said they could drop the lower unit and pull the shaft and straighten it for around $300. So, has anyone had any luck with getting one straightened and did they get it back straight within tolerance? I am a little worried that it would be close but not as close as a new one.

Now, if I buy a new shaft ($200) and I guess I will need new seals any shims or anything on this? I was also going to replace the water pump? Should I replace just the impellor or is there a kit I can buy? Will I need other parts? Any help appreciated
