225 promax overcharging?

[Bunger]

Had the Sebring out this weekend with the family and noticed the voltage gauge pegged out at 16v while running 4500rpm. It drops down to about 13-14 at idle. Voltage was getting high enough to where the head unit was shutting off. Turn both battery’s on and that dropped it enough to where the stereo would stay on. I have the old voltage regulators with the yellow potting. Could that be the issue? The tach works perfect no issues. 392977

Get rid of those yellow potted regulators and get the new updated ones. Had the same issue with my Pro Max a few years ago.

thats what what I figured. Do you know the p/n for the updated ones?

Tip...anything with a voltage regulator should have a battery switch installed and turned to OFF when you walk away from the boat.

I’ve got one. Just need to remember to turn it off now lol. Left the boat on the beach for an hour and came back and some how the trim relay got stuck and was sitting there forcing the trim down for god knows how long. Luckily didn’t fry the pump or anything it all still works.

I have it at home or call Fillers Marine they a supporting vendor and will hook you up.

The number is 883071A 1. These are fused and require some mods but instructions come in the box. Fullers stocks them.

thanks bud appreciate the help!

Got new regulators and I’m going up to the river this weekend to change them out. But I’ve been reading a bit, could the type of batteries I have be causing this? I’ve got a everstart marine starting battery and a dual purpose Napa battery. I don’t think they are deep cycle or anything.

[Bunger]

Keep reading about not to use “maintence free” batteries? I believe both of mine are. Not sure why it would be a issue. There not deep cycle or agm
gel or anything. Just everstart marine cranking batteries

[twinrigskier]

So what would be the best recommended battery to use with a 1997 225 promax ?

Thats my question. From what I’m reading a wet cell battery. I don’t know enough about batteries.

[twinrigskier]

So where in the same boat.... haha. You thinking interstate deep cycle from now on?

I basically read that anything deep cycle maintenance free gel or AGM is no Bueno. Hoping someone else on here can clarify though. Because I’m wondering if this is what is causing my high-voltage problem

[Dave Strong]

Pretty hard to find a non maintenance free battery these days. Starting battery any good non deep cycle 650 - 800 cranking amp should be fine.

[ So stay away from deep cycle? Starting battery only huh?

Starting battery to run the motor it's what they are designed for, not sure what the 2nd battery is for.

[I have nothing extra in my boat to run/start other than the engine itself. A wet Starting battery that gets its charge from a 40 amp stater would be better than a deep cycle in this case? And would help steer away from any type of electrical problems with that particular engine?
