Engine hatch vibration 360 DA

[Al Andalus]

I have a really noisy vibration coming from my engine bay hatch. This only happens when I am at speed and seems to be coming from just under the hatch around where the table leg sits or in the middle of the hatch just under the rear seat. The boat is a SeaRay Sundancer, 360DA/395 International. If anyone has had similar and are able to help me out or even point me in the right direction I would really appreciate.

Many thanks
Al

Have you checked your Alignment on the engines or have the props scaned recently? I would start there...

Thanks Siboatguy but the noise is more like a loose bolt or screw under the engine hatch or in that area. There is no vibration in the boat from alignment or props problems. The boat runs smoothly. I do have a table that fits in a recess under the engine bay hatch which I thought might be causing the noise as this was in direct contact with the hatch but I put some padding around this and it fits snugly so that is ruled out. All screws and bolts around the hatch have been checked and tightened.
