I forgot about this with the larger screws. Thanks for catching this.

Aluminum and stainless steel are at opposite ends of the galvanic scale so will attack one another strongly in a moist atmosphere, like sea air especially.
I already have my aluminum screws ready on the shelf just in case I need them. 🤞 Ditto that!

You should download the Service Manual from the ‘TSB and How To ‘ forum on this site, it has all your answers in it. It is in the ‘Documentation’ sticky.
I would agree with your feedback above. That's why I used alloy steel screws with a corrosion resistant protective covering. Similar to those used in marine applications.

'Metric Socket Head Cap Screws - Corrosion Resistant; Type: Metric Socket Head Cap Screws; Thread Size: M5x0.8; Length Under Head: 16.0000 mm; Material: Alloy Steel; Key Size: 4.000 mm; Finish/Coating: Blue Polymer.'
