Thanks. Nice love affair too.

That type of cooler needs flow across it to work. That flow can be from movement through the water, from inflow to the propeller, or from convection (warm water rising through grid, pulling cold water up from the bottom). On V-hulled boats they are located on the deadrise, part-way up from the keel, and benefit from both types of flow. On larger, flat-bottomed vessels they can be located on the rake just forward of the propellers, using propeller flow when moving but also convecting when stationary. On smaller flat-bottomed boats, like EDNA, there is no room on the rake forward of the propellers. If you put them on the bottom, they would be easily damaged when working in shallow waters, and there might be insufficient flow when stationary. If you recess them in the bottom there will be zero flow when stationary and the engines will overheat. So the trade-off is to put them on the hull sides for good convective flow, guard them with sufficient structure and fendering, and rely on good boat handling to prevent damage.

Did she give you that tire missing from her bow, hoping for one in exchange from your Prius?
