Supra SmartPlate

[DDD123]

When the Smart Plate is at 100 does that mean it is fully down or fully up? What is more fuel efficient? I tried testing it by holding RPM's and going from 0 to 100 and seeing if speed increased or decreased. When I move it to 100 it planes out better and the speed appeared to increase but it could have been a fluke.

I am trying to find the most fuel efficient way to cruise.

Smart Plate at 100 equals all the way down. Interesting thought on testing this. Intuitively I would assume that the less plate when cruising the better the fuel efficiency (not sure how much) but I could be wrong. I would think that to test this you would need set the cruise to maintain your speed and then adjust the Smart Plate and see how it effects your RPMs. What were your water conditions like when you were testing?

Yeah I should have watched RPM's and not necessarily speed. Definitely windier conditions and I had a headwind so planing out could have just streamlined the boat from the wind and increased the speed. I'll test again next time I'm out and report back.

Correct the smart plate at 100 will lift the stern up and set the bow down fully planing out. It will increase speed, decrease wake, and should increase fuel efficiency as well. Granted an SE is only going to be so efficient like our Makai, but it will for sure help out a little anyways

Thanks for the response! It is interesting that putting it down, creating more drag would increase fuel economy but I guess it gets more of the body out of the water so it doesn't drag the actual hull through. Gotta love physics.

Lifting is the key there, getting the hull out of the water on plane vs running surface drag friction. At 25-30 mph cruising, watch the size of the wake change when you go from 0 to 100, there will be a noticeable change. Engine sound typically changes as well, kind of fun to try different things out. If you ever ski behind it you will want to set it at 100 to minimize the wake.
