1980 115HP/I6 - replacing stator and switchbox

[hempfarmer]

Hi everyone:

My stator has finally failed (tested) and I am now debating how to proceed.

Currentely have a CDI stator and switchbox.

Questions:

1. Should I replace the stator and switchbox at the same time? As far as I can tell there is no problem with the switchbox but I have read on here that you should replace the switchbox when replacing the stator. The age of my failed stator is unknown but it is likely 5+ years old. The switchbox was replaced 3 years ago.

2. Is it worth the extra money for a OEM stator and switchbox? It seems that online everyone swears by the CDI product(good value and support) but I have also heard the mercury OEM stator for my engine is a much better product and worth the money. That came from a mechanice who has worked with both and is testing them all of the time.

3. I also read on here it is recommended that I switch to a flooded battery. I am using a AGM battery right now and I was told it may put more stress on my rectifier and in turn cause my stator to wear out sooner. Any truth to this?

Any feedback is greatly appreciated!!

....we always need the info on your engine (make, model, serial, hp, etc) to help better with these types of questions.

If you have a new switchbox, maybe you should just replace that along with the new stator, they say it is good practice to change both at the same time anyway. CDI products are good. CDI claims their stators have some internal regulation on their circuits to protect the engine from voltage spikes. All their stators are now open windings for better cooling. It is also important that the stator be installed in the exact orientation as the original. You also want to test the regulator/rectifier.

The serial is 7158643, made in Canada. Inline 6 with thunderbolt ignition.

Really curious what people have to say about the Optima blue top AGM battery being paired up with this engine. Some things I have been reading have me really concerned. Ex. charging at too high of voltage and damaging the batter.
