EME35AS - prop washer

Hi. I am new to gas engines. When I install the spinner back plate, then the prop and then the prop washer, the bolts that came with the engine seem to be too short. If I remove the prop washer, I am ok. But should I fly without a prop washer?

No, you absolutely need the prop washer to support the bolt heads and to create the necessary clamping force to retain the prop. Buy longer bolts but make sure they don't bottom out in the hub threads. Readily available at any good hardware store, building supply, etc. I assume there are such stores in Norway.

How easily should the bolt enter and go through the spinner backplate and the prop? Its very tight in my case.

Ensure they are high tensile bolts, Ie 8.8 or 12.9 Grade.
Dont Use stainless as they are around grade 5.
