Re: oil and water gauges
I bought the temp sending unit from catalinadirect.com. The sending unit they sell has the proper thread configuration. The gauges are from Teleflex. I removed my water heater and used one of the ports for the sending unit. However, if you have a water heater and want to keep it, I would think that you could tee off of the hose where it leaves the engine, but you may have to search around to find the right thread thread for the tee. Also, the sending unit has to be grounded to the engine in order for it to work. So if you tee'd it from the hose and not directly out of the engine you may need to jumper a ground wire from the sender to the engine.
I found that auto parts stores can carry the right thread configurations as it is common on Japanese made auto engines. The pressure sending unit needs an adapter for the Japanese threads but it can be found at the auto parts store. It is a standard pressure unit, but you need to make sure the electrical output matches the gauge.
As for an engine panel, you wouldn't have to get fancy and could make a standard flat panel out of 1/4" Starboard or Seaboard. It cuts easily with simple woodworking tools. I recently saw an add for a Panel Visor from SeaworthyGoods.com that would make waterproofing the thing pretty easy. I might have gone that route had it been available a year ago. Although, I don't know how much they want for it.
Shoot me an e-mail if you have specific questions. I'll help if I can.
