yes, those back spaces in my 2011 Eyra are very useful. I keep tools, back up troller props, prop wrench, wheel chocks two flat boat bumpers in the space in back left. And I use water proof tupperware (bread loaf size) to keep items that require it dry. In the space on the right side has the oil resivoir outside the fuel tanks and it is raised to make filling almost spill free. Jamey is right, you need to crawl around on and Eyra to appreciate the storage layout. If you get near LOZ 35.5MM you can check my boat. I have a ProXS 200hp instead of 250 and it still touches 70 with no trouble with much improved gas mileage. I am due to replace it later this summer so come on over to take a look.
