Ok, I read your other post.

MPH Gauge - Figure out what you have now - most likely a 4" VDO gauge. You can order these off the net with a search or go to your local Marine Supply store and order from the catalog.

Trim Gauge - I'm guessing you have either Inboard/Outboards or Outboards. Do you know if your problem is your trim gauges, wiring or trim lever switch? Usually the switch goes before the gauges. Figure out what brand gauges you have and see if you can order parts.

The bathroom drain - If you just need the stainless grate, pull it off and match it up at your local Marine or RV supplier.

The Portlight is more tricky. Do you know what brand you have? Taylor? Once you find the brand, do an internet search and see what you can come up with. If it is unavailable, you may have to pull the old one and take it to a plastics specialty company and see if they can make one for you. It will likely be expensive to have a one off piece made, but it may be your only option.

Good Luck!
