Issue with a Stator ass'y

[dompie99]

I finally succeeded to get this rig on the water element this week-end. but two things came up.

1: The mid section (Original) is a 1994, 225hp 3.0L, the replacement is from a 200HP 2000 3.0L injected. After two to three minutes on the hose, ( LWP ), it went up to 160, 165 on IDLE. It never did that before and it stayed at Thermostat temp ( 145* ) on hose. I went for a ride on the river and If I stay ar 3000 to 3500 rpm's, it remains at 165* on temp gauge. After discussion with Crankbearing, it seems that the tuner could be in cause and I should have switched the tuner BEFORE assembling it back together. Part number for the original is 826384 and for the replacement it's 833116A 4.

2: The stator coils under the flywheel went '' wako '' so I had a replacement and even this replacement was also (on a different cylinder ) WAKO so in undertook the coil switch-a-roo .. and took the defective coil and changed it with the same one on the other stator. I finally gor ALL ?'s to fire finally.

Could there be that some one might have one of those stator coil for a carbed 1994, 3.0L V6 on hand. ???

As for the mid, I will undergo the dismanteling of the power head AGAIN and replace the TUNER with the 225hp one. OMG what a mess.

If you are running the complete 2000 mid, i wouldnt mess with it... The '94 mid is a completely different animal... Exhaust housing is different inside, tuner is different and the '94 has a smaller water tube... I know the later tuner wont fit in the earlier mid, but not sure if the early tuner will fit in the later can...

[dompie99]

Unfortunately I found the hard way that the water tube is a lot bigger. And also the tubes (2)that comes from the thermostats output are also bigger.
One of the things you mentionned was that you were not sure about beeing able to fit the 1994 exhaust tuner to the 2000 can. I know i will find out this week-end but you throw me off my chair !!!!! Is anyone awsre that they might not fit because i don't think i have a choice i can't run the engine anywhere above 3000 rpm unless it start to get to 170* on both heads. And it's not a lean gaz issue.

I've been down this path putting an opti powerhead on a 94 mid.. The more I think about it, the early tuner won't fit in the later mid..
you are currently running a later mid and tuner and 94 powerhead?? Is that correct?

Opps.....wrong post. Please disregard..

[dompie99]

you're right. The ''can'' is from a 2000 200hp 3.0L and the ''tuner '' is from a 1994 225hp 3.0L ... do you think this is a disaster ?

[tony1204au]

I didn't think you could get the 94 tuner into the 2000 can.. The 94 tuner is half the size of the 2000... What adapter plate are you running?? If it's the 2000 adapter, that's probably where all your problems are.. In your shoes, I'd get a 2000 type adapter and tuner in there..

[dompie99]

I already and the adapter and tuner from the 2000...the motor is a 1994 carbed engine. The main reason I want to modify it is because it's not adequate for this engine and it keep the engine hot ( 165 on idle and on hose ) as compared to the 140* before with the old mid section for the 225hp 1994.
If I go beyond the 3000 rpm mark the temp rise. and I don't want to fry the engine again

[tony1204au]

Now I'm assuming you are running the '94 adapter and tuner. Putting the 2000 can on it, shouldn't affect your temps at all because the cooling side of things in your mid have not changed.. I would recheck things such as thermostats, poppet and water tube grommet/adapter first.. Personally I'd run the whole 2000 model adapter/tuner/mid since you have them, but I don't see these making a difference if you have a problem elsewhere..

[dompie99]

Your assumption is not exact. I am using a 1994 225hp 3.0L on a mid section coming from a 2000 200hp EFI or DFI (not sure). I did not exchanged any items from one another mid sections or not yet. HUrry up week-end so i could look into this


Crankbearing told me that the reason it's keeping itself hot could be that the exhaust tuner might not be '' in tune ''with the engine causing restriction and keeping a back pressure in the exhaust system. I know that on a two stroke, tne exhaust is critical up to a certain point.

Before with the original 1994 mid section, the temp was steady at 135 to 140 on the hose compared to now at 165 on the hose and on idle. I checked the Popet and it's okay, the water pressure ( on these beast ) is quite low, around 5 to 7 psi on Idle and a max of 10 psi at WOT..

[tony1204au]

I dont see how the later mid/adapter/tuner can affect your temps... Unless the water tube is split or the grommet is leaking... There is less restriction in the exhaust of the later tuner and a bigger water tube for more flow... Your water pressure numbers seem to be right..

[dompie99]

Honestly, I do not know where to look for this issue.

When on hose, I pulled poppet out, water was comming out, pulled thermostat hose, water was warm and flowing good,
could it be that the adapter plate is not exactly ''fit'' for this engine although I have my reserve, a 3.0L must me close to it anyway.
