The Suzuki is like this. You need to:
1. Take off cowl
2. Lift off the cowl seal.
3. Remove the pin that retains the cowl latch, and remove the latch.
4. Remove the philips head screws that hold the two halves of the upper cover together. From memory, there is one under the cowl latch, one at the front of the power head inside the cowl, 3 or 4 on the right hand side of the upper cover.
5. You can now remove the right hand side upper cover - the only thing still attaching it to the engine should be....the tube connecting the telltale to the block, approx 5mm diameter x 20cm long.
I haven't disconnected it, but assume it unplugs from the telltale 'nozzle' at one end and the block at the other. You can then blow through the tube / see if you get any water out of the block with no tube attached.
Let me know if you get stuck and I will double check mine.
