ARCO Marine Zeus 24V 7kW J180 4" Alternator w/Isolated Ground [4503]Zeus 24V 7kW J180 4" Alternator with Isolated Ground The ARCO Zeus 24v 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real world terms, a marine diesel engine at 1,500 RPM with a 2: 1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3. 21: 1 ratio

Zeus 24V 7kW J180 4" Alternator with Isolated Ground

The ARCO Zeus 24v 7kW alternator generates extremely high amperage at cruising and higher RPMs. This alternator continuously generates over 3kW (109 Amps) at just under 3,000 alternator RPM and almost 6kW (218 Amps) at under 6,000 RPM. In real-world terms, a marine diesel engine at 1,500 RPM with a 2:1 pulley ratio generates over 3kW, and a Mercedes Sprinter at 1,800 RPM with a 3.21:1 ratio generates over 6kW!

The ARCO Zeus 24v 7kW alternator turns on for cruising or at mid to higher RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact onthe  alternator lifespan.

A little greasy, stains hands, smells great
This tanning lotion is better than Planet Fitness lotion, but I am giving it time since I just started using it, but I can tell it smells delicious, lotion as well. A little greasy for my liking but it gets the job done! Make sure to use a glove as the stuff can stain your hands!!! The lotion goes on like BUTTER! 🧈

GREAT - Must buy!
Cannot reccomend these enough. Actually helps turn your burns into tan and reduce redness with the after sun product and the tan enhancer REALLY works. Be careful to let the brown enhancer dry if you're wearing white as it will rub off on your clothes but it did wash out!

Does not absorb all the way BUT STILL THE BEST!
This is THE BEST outdoor/by the pool/by the water tanning lotion ever! I have used it in my tanning bed for years. It gives you a STUNNING rich, brown tan after just a couple of sessions. I will say the browning lotion doesn't absorb all the way so it does and will make a mess! But it does NOT stain ever, it washes right off. Once I am done tanning, I just take a dry towel and remove excess lotion. The after tan lotion is amazing and will turn any little burn into a beautiful tan overnight! My all time fave! It smells like mocha and coffee which makes sense because there's coffee as an ingredient!

Love love love
I have never had a tanning product work so well for me. First off let me start with saying that how quick it works is based off of where you are in the world in my experience. For example, if you are at the beach or an island or somewhere the sun is closer to the equator, it works quicker. If you are somewhere further north, it takes a bit longer, but still not by much. I would say only about a 15-30 minute difference for seeing results varying UV index. This product has definitely made it easier to tan living up north. And the aftercare lotion with this stuff is *chefs kiss*. I would put the aftercare stuff on after laying out on the beach and getting red like Larry the Lobster, then would wake up the next day with a tan and moisturized skin. Plus, with working, it makes it harder to spend my day soaking in the sun(sadly). But I still have a great tan after a week. Also, I am a skincare finatic and this did not make my face breakout or anything. (It does also have a sort of molasses smell but it really isnt horrible). So yes, buy the product. It’s so worth it.

long, tan, & handsome
Love this product. Bronzes even the palest of the Irish type. The after sun lotion is AMAZING. I use it anytime after I spend time in the sun - it really helps lock the color in and keep your skin so smooth and lush. I ease in, I wear it outside for a bit then put on sunblock until I have a good base tan - everyones different, without sunblock you’ll still burn… (since this isn’t sunblock) Putting it on is my least fav, hate the feeling of it on my hands, will get on everything in a 20 ft radius of you, but once it soaks in you’re good to go. You will smell like coffee for the next few hours, which is nice if you enjoy the scent.
