That's not a trunk - it's a hose!
If you have a long shaft engine and the trunks are towards the edges of the transom you shouldnlt have an issue.
My new trunks when I got them were so long that they stuck above the trasom by about 3". (76.2mm for those of you who think metric) wghen folded. They would have fouled my prop spectacularly, but they only need to be long enough to get above the waterline at rest (+ a couple of inches / few CM for dealing with waves) to function properly- so I cut mine level with the top of the cut-out for the engine - if the water gets higher than that it has a much easier route into the boat anyway!
