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

[Van Wildonher]

Hi guys, I purchased a boat that has been sitting a while it has a 200 and a 225 on it... Model numbers e200txetf and e225txerk now the thing is, the engines look like they are from 1986 according to the cowlings, lower units, carb hose route, etc. yet I believe these model numbers are 1993-94.

I don't have pics right now, but it looks like the lower cowlings were cut to be able to house the exhaust/garden hose flush hook up. Did the 1986 motors have a garden hose flush hook up?

I had the model numbers so I went ahead and ordered thermostats/water pump kits for the 1993-94 model. The 1986 models seem to have an o-ring that goes on the top of the drive shaft and no o-ring under the impeller, and the 1993 models have an o-ring that goes under the impeller and no o-ring on the top of the drive shaft. Of course I didn't notice any of this until I replaced the water pumps and and installed the lower units.

I did not notice any o-rings on the top of the drive shafts when taking them apart, there were however o-rings under the impellers.

Basically I need to find out what exactly I have here so I can know what to do. I'm also trying to find out if water is supposed to come out of the starboard side hose/pee hole things. This hose is connected to a throttle valve thing but no water comes out. (I'm running on muffs because I don't want to launch and haul if the water pumps aren't correct) This is the only hose connected to the throttle valve thing and it's not plugged. (it goes from the pee hole to the throttle valve) I didn't see a way where water would even be able to get into this hose.

The OEM manuals for the 86 and 93 don't show cooling hose routes that I can find.

PLEASE HELP!

According to model number, it is a 93 and 94 engine.
Yes, water is supposed to come out of the 'pee' holes.
Running on muffs may not give you enough water for the system to work properly.
try to get some gig buckets, waterlevel ABOVE pump, and run. The only way to test on land if pumps and cooling are working properly.

Why would you have opposing motors that are not the same horsepower? It seems to me that the smaller motor would need to have it's own throttle cable system and would never match the bigger motor in power or rpm.

I do not know. I'm not positive but I think the carbs are from 225's because there are no adjustment screws in them. Maybe that makes the 200 a 225?

Like I was saying, I do not know what engines these are, everything on them look like 1986 but the model numbers say different...

My question is how, because by what I can tell there is no way for water to come out of this hole. Water does shoot out of the small hole by the exhaust where you would screw the flush adapter into...

Is it possible that it only has newer midsection brackets? (where the model plaque mounts)

A 1986 would have power boost cooling valve like you describe and no poppet valve/cover on rear of block and dual packs on the heads unless ignition has been changed. If is a 86 motor its the smal bore 2.7 block. The only difference between a 200 & 225 is carbs as venturi opening is 1/16 larger.

Can you explain this poppet valve to me? I also know that it takes the thermostats from 86. I think I have some pictures, I'm going to put them up now.

If you can see the last picture well you can kinda see where it looks like the cut the lower cowlings to fit the exhaust. Where I want to know if water should come out is the small round black thing above the cowling bolt in the last image.

Oops I messed it up. Will fix and post again...

The upper cowls look like those from 1988. Both engines have water control valves, so they are not from 1993 or 1994.

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

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

Is water supposed to come out of those valves? They only have one hose connected to them (it has places for three) that goes directly to the little black rubber grommet hole seen in the picture.

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

If these are from 1988, does that mean the drive shaft in the counter rotating engine spins the opposite direction? I installed the impeller key thinking both drive shafts spun clockwise.

The impeller kits were for 1993/94 models.

I do not see the part number 0345586 GROMMET & INSERT on the 1988 model schematic.

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

It does not matter which direction you place the impellers' vanes, they will align correctly as soon as you run the engine under load.

Both engines turn the driveshaft clockwise, so the waterpumps are the same and turn the same. It's the gears in the gearcase that function differently to determine which way the propeller turns.

What is just behind the flush inlet inside the lower cowl? Can you get a picture?

After 1992 the gearcases changed to two part driveshafts. The cranks on the newer engines had the o-ring inside, rather than on the driveshaft. The newer driveshafts were of a different length.

I don't think that you will find that particular part numbers on any of those engines parts diagrams until 1993, when they first started using them. The part number was 0337782 in 1993, superseded by 0345586 in 1999.

If you want to go back to the original part, see the lower cowl diagram.

The engines are not earlier than 1988 because it has the wrong powerpack for the earlier engines, among other things. It's not later than 1988 because from 1989 on the motors came with the extra PT&T switch on the cowl, among other things.

I was talking about the key for the impeller, it says to have the sharp end pointed toward whichever way the drive shaft turns. So I guess that's not a problem.

I'm not sure what you mean "What is just behind the flush inlet inside the cowl?" I had the whole black thing (grommet) off yesterday and there are two small rectangle looking things and a tube that the black thing goes on. The black thing to the rectangle things are secured with zip ties and the tube has a hose clamp.

I know the lower units are from 198? As they don't have the removable screens without removing the lower unit and water pump. So for sure I have installed 1993 water pump kits in these 198? lower units. And I for sure installed the o-ring inside the pump and not on the top of the drive shaft. (which is how I found them)

I still need to know about the throttle water valve thing and if the pumps will be ok like this or what...

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

I don't have a barrel to test in, and I don't want to launch the boat as it is very hard to haul out with what I have available to me.

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
