Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

I don't see why you cannot test on muffs. The tell-tales should be enough to let you know if the pumps are working.

If you don't get some flow from the exhaust relief with the engine running, you either have the exhaust gasket loose between the gearcase and the inner exhaust, your water supply is not adequate or you have not waited long enough.

If you don't have the grooves for the 0-rings below the splines at the top of the driveshafts, then the driveshafts are not the earlier ones used before 1993

The water shoots out of the black grommet thing like crazy. It has a hole in it too, makes me wonder if that is the only place where it "pees". Can you confirm if I'm supposed to get water out of the small black grommet on the starboard sides of the cowlings that is only connected to the throttle valve? It's the only hose on the throttle valve and it goes directly to the little grommet on the starboard sides of the cowlings.

I don't remember seeing that slot for an o-ring on the shafts but damn it I can't be sure without dropping them again.

Are the drive shafts interchangeable? I thought one was longer than the other?

In any given year, with the same case, length and HP, the driveshafts will be the same length.

So being I have an older case it isn't possible that I have the newer drive shaft? I'm sorry but your post confused me.

Oh and I'm heading to the boat now, any specific pictures that would help?

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

Here are some shots of the cowling cut out and the back of the engines, and one of the hose that is only connected to the throttle valve straight to the small round grommet. I don't know if they will help any...

Are the small hoses that go each cylinder for water too?

Those run to the recirculation check valves; they help to drain excess fuel mix.

86-88.
In 89 they came with the ejector valve and BIG hose for the indicator (pee) hose.
But most likely a couple of 'frankensteins' made up of a little of this and that.

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

I put them both at 1988, both big bore loopers, with the port motor having the counter rotating drive.

I agree with ezeke on years as 1986 CR lower unit wasnt offered, 1987 the engine started and ran backwards to make a CR unit and 1988 was 1st year of real CR unit.

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

I guess I will have to drop a lower unit to check and see on the o-ring thing. If it does have the slot should I just install one on it and leave the one in the pump?

Nobody knows if water is supposed to come out of the small round grommet on the starboard side? Or how hoses are supposed to be connected to the throttle valve thing? Maybe it's bypassed and that's why there is a hose with a bolt plugging one of the lines out of the thermostat cover?

Thanks for the help!

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

Ok, I see now that the throttle valve is not connected and there is no way water can run out of the small round grommet. Is this a big deal? Should I try to connect it up again? Looking for some opinions on this, I did read that a member dhardley (I think) had a write up about how to bypass it, but he has like 14,000 posts so I didn't want to look through all of them.

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

You should have water flow from the tell-tale on the starboard side of the lower cowl on both engines. The tell-tale flow ran from the outlet on the adapter on the 1988 motors (see #35 on the midsection diagram).

I will have to look for that next time I'm at the boat. I know that the throttle valve is connected via hose to the starboard side holes. But do I really even need this stuff connected? I already have a tell tale coming out of the back of the engine where the flush adapter/exhaust is...

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

Somebody has been mixing up used parts to make up your motors. The midsections with the Fast-Trak trim system are from 1993 and 1994 according to the model number tags. The Fast-Trak trim system didn't come out until 1991. The engine blocks and motor covers are from the older 1988 or so engines from looking at the thermostat and power-boost cooling valve. The stb. motor has broken throttle-spark dwell linkage which is not available any more, but you might find one used somewhere.

Your one piece driveshafts and o-ring on them means that the gearcases are older than 1992.

You may have fun getting the correct parts so it would be best to have an experienced J-E tech look them over to see exactly what has been mixed-and-matched.

It's kind of like Johnny Cash's '56, 57, 58, 59 Caddy song.

I can't do that because I'm in Honduras. So I'm on my own. What do you mean "throttle-spark dwell linkage"? Are you talking about the black plastic knob that adjusts the idle speed? If so I have a spare on another engine.

So in my mind I'm good with the tell tale coming out of the flush adapter/exhaust and don't need to worry about the small starboard hole.

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

When I was ordering parts from the model numbers on the plaque I got 4 thermostats/gaskets for the 93/94 model. I did some reading around here and it says I can convert to using them with a thermostat cap and spring from 93/94, does anybody know if I need any other parts to do so?

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

They did need the o-ring on top in case anybody else comes across this.

 

[Dhadley]

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

Both blocks appear to be 3 liter open deck blocks (1988 - 92). The starboard block is a 1991 or 92. The port block appears to be from 1988 - 90. Kinda hard to tell for sure on the port motor but if the tab on the head gasket has a notch in it, it'll be a 3 liter from 88-90.

Re: Need some GOOD info, this is a tough one. 200/225 Johnson questions

Hmm, well it looks like I don't have a spare spark advance link assembly like I had thought. Anybody have any ideas on how I can fix it being that they are no longer available?
