Default Enertia Eco vs Enertia Eco XP

Anyone have experience between these two props? Mercury racing came out with the latter and you'd think they'd be similar, but from their own websites, the Eco claims bow lift and the Eco XP claims stern lift leading me to think they have a different blade cup arrangement. At the same time, Racing also says they are to fill the gap between the different pitch sizes.

Bumping this thread.

I'm testing a 21p Eco and can only hit 6000rpms. However i can manipulate the RPMs by raising the jackplate but I see no increase in speed only RPM.

I'd like to get my hands on a 20.5 Eco XP

If they're claiming the XP provides more stern lift, then they have taken some rake out of the original Eco. It was my understanding that the XP was to provide "extreme precision" when dialing in 350 and 400 Verado powered boats. 16.5" - 22.5" pitch sizes available in 1" increments with the XP vs. 17" - 23" pitch sizes available in 2" increments with the standard Eco.

In my experience, Eco props lift the entire vessel compared to other props. We haven't had the need to try any Eco XP props yet.

100% right about the prop lifting the entire boat. I was surprised by the extent of the lift that the ECO provided.

I've never heard of the XP Eco increasing stern lift. Where does it say that?
The stock Eco does carry the entire hull and runs well.

Talked to Scott at Merc Racing and he says they remove a little bit of cupping in certain areas to achieve the extra RPM in the XP. With that being said I asked him if the slip would increase? His response was in the dual engine configuration it wasn't noticalble but they hadn't tried it on a single.

I'm thinking about getting a 20.5 XP

Did you pull the trigger on the XP? I'm thinking about getting the 19.5.

Thanks

Negative.

Ordered a 20p from Ken yesterday. He called me this morning to tell me they aren't shipping until October 23 from Mercury... However that shipment date isn't guaranteed, it could be even longer. P retty much sucks! haha

I went with the 20 due to the fact I could mod the prop to help with performance as opposed to take a larger pitch prop and work it backwards because I couldn't get the RPMs up.

We shall see. I just have to wait for it to get here.

Does anyone think the XP would be a better suited prop on a stepped hull like my Donzi ZFX? I am running twin Yamaha F350s and seeing 68mph @6100 rpm with the Bravo-1 4blade 24" props turning IN.

When I tried the 17 Pitch Eco It sold me on the improvement of no slip what so ever., when compare to my Yamaha SDS. But I could not get it to turn as close to 6K as I would like. So I purchased the XP. at 16.5 pitch. And Now I'm up to 5800 and Have not notice any slip yet. Lift and fuel has improved. over the Yamaha Prop. I'm running a 300 single and this prop looks to be a winner.

How does the ECO run compared to the Mirage Plus or Tempest Plus of the same pitch??

Echo Xp is a larger prop. Repowered a 36YF with the 300v8 and ran the mirage 23p old props until the 21.5 XP’s came in. Same speed pretty much out of both props but the hole shot is much much better with the XP and it’s the right prop for this boat. 1.3mpg @38kt cruise with matching rpm across the board. Mid range of the XP is impressive and it pushes right through the step like a ski boat now. We often fish very heavy and this XP setup should be golden for us. Here is a pic of the motors with the 21.5 XPs. They are huge compared to the mirage

You will need 2"-3" LESS pitch of Eco than Tempest Plus.

I ran a 19 enertia ( not Eco) on my 300 Verado. Then swapped to a 17 enertia Eco and 17 Rev4. WOT rpm is the same between those 3 props.
Eco is a smooth prop, whole hull lifting, good top end performance, but terrible for reverse thrust and around the docks. The Rev 4 is bow lifting on my boat, not excessive but noticeably different, just shy of the Eco top speed, a little slower on hole shot, but much better around the docks. Both outperformed the enertia in holeshot, top speed and fuel burn.

Was there a difference in fuel economy?

yes, the Rev 4 and Eco both improved midrange fuel burn from about 10.8 gph to 10.1 gph at 28 mph mid range cruise speed. Those 2 props appear to be about the same with a small nod towards the Eco, but not much.

In my experience, the Yamaha SWS Series is more efficient than the Rev4 and the Enertia ECO is more efficient than the Yamaha SWS. The Rev4 has 14 5/8" diameter and the ECO is 16. That is a huge difference.

Here they explain it in a short video, how adding the 4 blade does not help.
