Glacier Bay Motor Switch TRP215K-B, for 2006 Boat

our toggle switch is very corroded and needs replacing but can not find the switch plus the housing to rewire it. Anyone can help is greatly appreciated

Thank you very much, was hoping to find a prewired switch

the photos do not want to open under the next window asking for the url address

Here is a bit more info on the issue, Has low power to turn the motors over, twin 06 Suzuki, 150's. They either click or turn over very slowly. Terminals cleaned, 13 Volts in all 3 Batteries, 18 Volts at starter. Any Idea on where else to look, thought it might be the toggle switch but we can not find a replacement LIKE the old one.
