Really want to upgrade stator on Evinrude 88 SPL

[shane0926]

Hello,
I have been searching the net for some time looking for information pertaining to a stator upgrade for my boat. I've been dealing with the issue of dwindling batteries while out for the day. My boat has a lot of heavy draws on it, most notably, a large sound system. I didn't realize that I'd be facing this issue after choosing to purchase an outboard...but, here I am...

The boat has stock power trim, so it should be equipped with a 9A stator (OE part # 583536, 583340, 763767) and it just doesn't quite keep up with my uses depending on how much floating I plan on doing that day. I'm looking to get in the realm of 15 - 35 amps if at all possible. Not sure if this has been done on this motor, and I don't quite know where to start.

I know I would have to upgrade the rectifier and potentially wiring as well, which is fine. I just don't know if there is any sort of standards for stator physical sizing, spacing, hole location, etc...there are so many different ones that I find on many sites.



I have already installed a Blue Sea Systems battery switch and charging relay that allows 2 batteries to be charged while saving one for starting only. This makes the best of a bad situation, but I'd rather fix it right.

Any insight into this issue would be greatly appreciated, this is something I REALLY want to do!

Thanks!

Have you checked CDI Electronics?

Your stuck with a 9amp... only way to get 35amp is to upgrade to looper engine 120-140hp

Unless you plan to run the motor for an extended period of time, you aren't going to keep with up the demand even with a higher output system, although some people do cruise around with the sound system blasting. Anchoring in a nearby cove doesn't allow for much charging time.


​I had one of these motors and never looked under the flywheel, but on some stators there's enough room to mount another set of charge coils. It's up to you to see if this can be done and figure how to do it.

Thanks for the reply. I am definitely willing to do it. I will be removing the flywheel to take a look at things. Do you know if there is any sort of standard among the physical dimensions of available stators? (Spacing between coils, etc.?) They all look very similar.

Look into mounting a belt driven alternator from a small car.----Would have to modify the cowling on one side or the other.----A real " power bubble " so to speak.

Thanks, I thought about something like that, but I would hate to destroy the cowling...a possibility though.

Yeah, bolt a good sized pulley to the three flywheel bolts and fab a bracket to secure to head bolts? Hoods are cheap and plentiful - buy a used one to hack up.
