I want to relocate my gauges to the port side coaming, up from the original ankle height location.Considering the fact that my boat is now 32 years old (hull number 8) I thought it might be prudent to replace all the gauges, switches and choke cable while I'm at it.This may be a dumb question, but are there marine grade gauges that I should be shopping for?I'm thinking that being up so high they will occasionally be hit with salt spray.Will I need to purchase new sending units as well?Also is an extra length choke cable readily available?The longest I have found locally is 6'
