I think Mark diagnosed this properly. I still have my intake heaters but they don't cycle as much ever since I added Wolverine pan heaters.

sorry for my ignorance here but I think I can hear them turning on and off..... definitely can feel it in the engine sorta up/down kinda thing?
Your voltmeter will tell you when the intake heaters cycle. I know that with my boat I allow the first cycle and when the volts come back up, I hit the starter.

I am out on the water After just having had my alternator replaced. When I come up to speed my voltage steadily increases until it hits 16 V and I get an alarm. When I bring it down off of plane and go back to idle speed the voltage drops to 11.8 V. When I come back up again, same thing it’s slowly climbs to 16. Does anybody have any thoughts on that?

The voltage regulator is part of the alternator. Sounds like you may have a bad alternator. Your symptoms are exactly what I had when my alternator went. I replaced it and two weeks later the other failed.

Thank you for the quick reply. The alternator was just replaced. I replaced it because it was not charging at all underway. Today's issue was the first run with the new alternator. Both alternators usually ping pong back and forth at low rpm's from 12-14.4 volts. As soon as I am above ~12-1500 rpms, both immediately read 14.4 volts. The new alternator (the one in question) does not automatically go to 14.4 once I bring the rpms up. It slowly rises .1 volts at a time from 12 volts to 16. It takes 7-10 minutes until it gets that high. I bring it back to idle, the voltage drops to ~11.9 or so. I come back up on the throttles and it rises slowly again until it is too high.

The back and forth is likely the intake heaters cycling. They will do that until the temp is up or the rpm exceeds around 1400. The internal voltage regulator should not allow that 16 volts. If the gauge is accurate then you probably have a bad alternator. I'm assuming your alternators are the same as those on the 480CE which I owned. It's a PITA but you could swap sides and verify.

Due to high winds, the mothers day cruise was a bust :-( Will be at least next weekend if not later until i can get out. Sorry.

Just looking through the PO's maintenance records (thank goodness he was very meticulous!) and noticed that the 8D house batteries were replaced June 2020. However, they were replaced with "Flooded". How long do you think I will get out of them? Any special care I need to take of them (beyond making sure they have water?). My preference would be to switch to AGM's eventually but no sense in just spending money on new batteries when I don't need to.
Thoughts? Input?
Thank you,
Tim

Finally received the JL 880 Tower LED speakers and got them installed yesterday. Happy Mother's Day to me!!! (Luckily the Admiral was in favor of this addition LOL)
The pictures are a little skewed as I had to re-size them so they would upload in the right direction. The weather may LOOK nice yesterday but it was only 44° and blowing from the north off a chilly 47° lake Michigan. BRRRRRRRR

I run my boat a lot. I usually stay at anchor or moorings on the weekends so I am always using the house batteries. The boat is at the dock hooked up to power all week. I have flooded batteries and I usually get 4 years them. I don't know how much more I would get from AGM's. I have never had them.

When only on the batteries, how much time can you typically get out of them before they are drained down where you need to start the genset and charge them back up?

I just received my new sea water pump from seaboard. Has anyone swapped theirs out. I am doing the port as that is leaking and easier to access. Any tips or tricks that I need to know
Thanks
Thanks

I have not really tested the limit. I run the genny each morning and evening for an hour or so, or to run a/c appliances and the water heater during the day, charging the batteries as I go. I leave the boat all day and I have left it for a couple of days with the refrigerator running off the batteries and have had no issues. I hope that helps.

I'm talking about out on the hook without the generator.

Thank you. Going from the Clarion stereo to the fusion, was the wiring pretty straight forward? Any gotcha’s that I need to be aware of before I get into this project?

Very straight forward. I can't think of anything that would snag you up.

Very very easy and straightforward. I did both of mine a couple weeks ago and port took 15 minutes starboard took about 30. leave the intake hose and output hose on the housing and just remove the four bolts on each housing plates. Then remove the two bolts that mount the pump to the block.
You don’t have to use any gasket sealer just the O-rings that came with the new pumps.
