Sea Ray SDX 270 Shore Power

[Weston White]

Hi all, first time post here and future Sea Ray owner. Been doing a ton of reading through past posts but can't seem to find a clear answer here. We just purchased an incoming 2021 Sea Ray SDX 270 that will come in 2021. I can't seem to find any documentation on shore power requirements, specifically amperage requirements. Our community docks share a 20 amp circuit and I'm trying to determine if a standard 120v/20amp circuit will suffice or if we need to upgrade.

Thanks in advance for the help and insights!

Most marinas provide 30amp 120v power. Double check to see. I wouldn’t trust a regular style 120v extension cord to hook up to the boat. Most have inadequate shielding and would be dangerous around the open water.

Thanks for the reply. I’m tempted to pay for dedicated shore power but I see other similar bow riders with an adapter for 30 amp to a standard 120v. It’s a community dock so I’m on that struggle bus.

The Sdx 270 does not have a shore power option, just a 120v battery charger. It will draw about 3 amps max. If your power pole just has regular 120v gfci outlets, use a high quality extension cord rated for the amperage of the breaker. If it has shore power outlets and 30 amp breakers, there is an issue with overloading small cords with a 30 amp breaker.
That said, you will not have a galvanic isolator and your 120v ground isn’t tied to your dc common, so I would be leary of leaving it plugged in full time while sitting in the water. Doesn’t really meet ABYC standards.

I use my 30 amp shore power for my trickle charger. I wouldn’t have an ordinary extension plug anywhere near my dock. Safety first!

I think you may be confused on what you're getting. Shore power isn't an option with that boat. You're probably thinking of the onboard battery charger option which just needs a simple, 120V, 15a plug (in other words, a commonly available extension cord).

Unless you asked the selling dealer to specifically install shore power for some reason?

So you're right, on the SDX 290 that we demo'ed it states shore power which I recall seeing the 30 amp twist lock. I just looked back at the cut sheet for the one we ordered and realized it says on board battery charger, not shore power. I had it in my head wrong.

So with on board charger, that is just a standard 120v extension cord?

Sorry for the dumb questions! Just trying to be prepared come spring time.

No worries!

Yes, just a standard extension cord - you don't even need a heavy duty one. But I would suggest an outdoor cord for longevity's sake. On your boat, you'll find a port with a rubber cover that flips open to reveal the male end of the cord from the charger.

Thanks for the tips and feedback. By chance, do you know how many amps a trickle charger requires? A Google search shows about 2 amps, does that seem right?

 

[paulswagelock]

As stated above, less than 3 amp.

The charger your boat will have is not a trickle charger - it's a more powerful charger, but a smart charger, so it has multiple phases that it can switch through. Take a look at what Paul mentioned above for power draw.

Edit: Take a look at what Paul mentioned TWICE above...

I am waiting for delivery of my sdx290, and we have shore power option ordered. Is shore power on sdx290 actual shore power or just a battery charger as it is the case in sdx270?

As noted above shore power is different than just a charger. Shore power is shore power... you will have at least one 120V outlet on the boat. You probably got the electric grill? Which is one reason why you'd then have shore power, as well.

Thank you for the quick and helpful response. We have not speced the grill, and we also did not spec the inverter. Just the shore power. That is why I am asking. If its actually shore power (as stated) I was expecting in my case (Europe) at least one 220V outlet. If its not the case, then I would be better of with adding battery charger myself (since shore power option is more that 3K EUR). Thank you for any aditional feedback in advance!
