Stator question

[phebus1]

Can you replace a 9 amp stator with a 16 amp stator without replacing any other parts?

Motor is a 1984 Mercury 115 inline six.

Was looking at CDI's website and saw a listing for both for the motor, but did not know if I had to replace with the same amp rating that was on there now, or if I could upgrade. Stator needs replacing due to the insulation on the wires breaking down.

Thanks

Re: Stator question

I can't answer the question about interchange of the 9 and 16 amp stators but IF (repeat IF) it is possible you would also need to change the rectifier as it probably is not capable fo handling the additional current. Check the rectifier part numbers to confirm this. Same goes for the regulator if the engine has one.

Re: Stator question

The CDI stator for your engine (174-5456) is only offered in the 9 amp series, the 174-5456-16 is for V-6 engines...

Re: Stator question

Thank you very much. I saw a listing for both on the CDI site, but did not know which was specific for my engine. 9 amp it is.

Next question. Is it preferable to stay with the oem part, or is the CDI unit as good, or possibly better?

Thanks

Howdy phebus1; Would like to offer tip if you want it. I purchased a seloc motor manual compensatory to motor I own. Found it to be invaluable tool for do it selfers Happy & safe boating to you.

Re: Stator question

I have the Mercury manual, and have found it invaluable, but it won't answer questions such as if the stator can be upgraded to a higher amp model or if aftermarket parts are as good or better then oem.

I find this site invaluable for that.

Thanks

Re: Stator question

Rarely is an aftermarket part better than OEM. If you think about it, the OEM manufacturers to critical parameters their motors demand. And they test the motors to those parts - not aftermarket. The extra money you spend for OEM is a wise investment. Can't go wrong and warrenteed. Good luck.

Re: Stator question

Why don't you cut the wires close to the stator and splice some new ones in? Heat shrink tubing and some bare butt connectors work great.With the plastic off the connectors you can see that all the wire is in the connector and lined up properly,then put the shrink wrap over the finished product.

This I disagree with as a OEM stator is only has a 30 day warranty if installed by a DIY customer and most dealer have a no return policy on electronic part installed by customers. CDI does offer a 1 year warranty no matter who installs it and Sierra/Teleflex has a limited lifetime warranty and they pay labor and towing if installed by a Sierra/Teleflex dealer.

IERRA INTERNATIONAL INC. (“SIERRA”) warrants its products to be free of defects in workmanship and materials for the useful life of the product (the “Warranty”). If a SIERRA product fails to comply with the Warranty, SIERRA will repair or replace the defective product free of charge. The Warranty is subject to the additional terms, conditions and limitations set forth below.

Warranty Claims for Professionally Installed Products:

For any SIERRA product that was originally installed on a vessel by a dealer or other professional installer that fails to comply with the Warranty, in addition to repairing or replacing the product free of charge, SIERRA will also reimburse the customer for reasonable labor charges incurred to replace the product, and reasonable towing and other similar incidental expenses incurred as a result of the failure of the product to comply with the Warranty. Labor will be calculated based on the installer’s posted shop rate that is competitive with their local market rates. The original work order along with the original invoice and a copy of the new re-work order must be provided to SIERRA to file a claim for reimbursement of labor expenses. Towing charges will also be paid based on reasonable and customary rates in the local trading area. A copy of the original invoice for the towing service must be provided to SIERRA to file a claim for reimbursement of towing expenses.

Re: Stator question

Insulation is cracking off the wires as they come throught the plastic fitting on the bottom of the stator. So, unless I modify it, there is no room to splice. Only option would be to completely replace the wires coming off the stator. I kind of like staying with the original wires with the color coding (striped, colored wires), so if repairs or testing is ever done in the future by anyone, they know what they are dealing with.

Re: Stator question

All aftermarket stators are color coded correctly, go with the CDI ....

+2 what Fazt said on post #9

CDI or Sierra for electrical parts, ALWAYS.

Re: Stator question

Let me add to the dogpile, IMHO the CDI replacement parts are Better than Factory. I have Never had a CDI part go bad but have replaced tons of Merc OEM electronics! And it's hard to beat the much better warranty.

If you want to improve voltage regulation on your Tower of Power, pick up a Regulator/Rectifier assy which you can mount on your electronics plate or another suitable location, it'll be a big improvement over the unregulated voltage output of the older-style "square" rectifier.

CDI part # 194-5279 (bullet connections) or 194-5279R (ring-tongue connections) are typical examples of what you could use for your Inline Six. Use the Search feature and you'll find many threads regarding the V. Reg. upgrade.
