"1990 Evinrude 175 XP. found a little bit of black goo on motor underneath the front of the stator. not very much but some. does this mean bad stator? any way of testing?

if bad, can/will it hurt to run it until i can get a new one?"
 
"That's the first sign of

"That's the first sign of a failing stator. Those 35 ampere stators run very hot. This will result in weak and eventually no ignition. Replace it as soon as possible.

As the stator grows worse, you will have excelent spark when cold, but when hot, the ignition will be affected. Keep a eye out for this condition."
 
"joe, here is my situation.

"joe, here is my situation.

my engine shows as a 1990 175 on the plate but everything on the engine is different from the Seloc diagrams and some parts installed. I have a 10 amp reg/rect installed on it (585195) and the wiring is pretty much the same as a 1989.

i see what is supposed to be there and what is there and it's very confusing.

I am pulling the flywheel off tomorrow to replace the reg/rect. I bought the 35 amp to replace the 10 amp but am not sure if the stator is a 35 amp or another one.

will post as soon as I can."
 
"If a 35 ampere stator, there

"If a 35 ampere stator, there will be two large black coils at the rear portion of it, and most likely one large black coil at the front of it.

The flywheel will have cooling holes near the outer rim area."
 
the flywheel does have vent ho

the flywheel does have vent holes but why would someone put a 10 amp reg on an 35 amp stator or is it just a matter of cost?
 
"I just looked that number up

"I just looked that number up and it is indeed a 10 amp reg/rect assy. If it looks like someone has replaced it at sometime, I would assume that whoever sold it to the previous owner didn't know what he/she was doing, and the boat owner, not being a marine mechanic wouldn't know any difference.

Or if it was installed at a outboard repair shop/dealership.... well, that says something for the mechanic wouldn't you think?

A boat owner would need to be a complete idiot to go that route intentionally."
 
"pulled the flywheel today and

"pulled the flywheel today and installed the new 35 amp reg/rect. goo was present on front and back of stator. will order one tomorrow. if i install a new stator, do i have to do anything with the flywheel and its' magnets? will everything fit ok and work ok as well? i guess i should replace the power pack as well just to complete the "electronic rebuild".

any suggestions?"
 
"what exactly is the black goo

"what exactly is the black goo and why do these stators meltdown?

if this is such a common occurance, why didn't OMC fix it? if not a common occurance, what causes it?

just tryin to figure it all out !!"
 
"The magnets should be attache

"The magnets should be attached to the flywheel securely, separated by (approximately) a 3/8" gap. If any of them have come loose, the surfaces will require cleaning, and the magnets will need to be epoxied back in their spaced locations.

The 35amp stators run extremely hot, too hot! This, in time, results in those large black coils releasing their inner insulating properties, oozing out of their casings.

In my opinion, this is an engineering goof. Who really requires a 35 ampere charging system. The melt down will occur again, just a matter of time.

all magnets seem to be secure

all magnets seem to be secure but what i was wondering is the distance between the flywheel magnets and the new stator magnets going to be ok since the flywheel magnets are worn and the new stator magnets are new?

what else has to be done after the new install of the new stator?
 
"After installing the new stat

"After installing the new stator, as long as you now have spark and the charging system is functional, nothing needs to be done.

There are no magnets on the stator, only coils.

The flywheel magnets do not touch anything. They simply create a magnetic field as they pass by the stator coils. What makes you think they would be word?"
 
just thought the wear factor m

just thought the wear factor might come into play. i am probably going to replace the powerpack as well. is the timing going to be affected? do i need to do a sync and link?
 
"yes,.and yes,..........or ,u

"yes,.and yes,..........or ,u can inst it,and flip a coin,........which,is the professional,way to repair that exp eng.u decide........"
 
"a few posts up Joe says "

"a few posts up Joe says "who needs a 35 amp stator anyway."

would it be a bad idea to put in a 10 amp stator and regulator instead of 35 amp? i know the book calls for a 35 amp system but if it is not needed, what's the harm? i don't fish tournaments and don't have all the fancy equipment the tourney fisherman use/need so could the 10 amp system be possible?

just trying to save a few bucks if possible."
 
"update: installed new stator

"update: installed new stator and powerpack today, along with new 35 amp reg/rec 2 weeks ago. new battery as well.

she fired right up on the 3rd crank, went into quick start mode, then idled down properly. found 1 plug not firing. changed plugs with one that was working and the miss followed the plug. will replace plugs tomorrow and sea test as well.

thanks for all the good info earlier."
 
spoke too soon !!!

went bac

spoke too soon !!!

went back today and boat would not start. didn't even hit once. no spark at all.

anyone have any ideas?
 
that leaves the trigger and th

that leaves the trigger and the timer base. check these by the manual
 
what would cause the timer bas

what would cause the timer base and trigger to go bad since last friday? it ran like a champ after i put it all back together.
