I have the Arid 2 zone system.
Think I’m on my 3rd year with it.
Does what it’s designed to do..
I use standard drip shaft packing so, during a run I get a small amount of water in the bilge.
The Arid machine works well for this..
I just completed my AP install.
Started the process 10 years ago…time fly’s :)
Its all outdated Raymarine stuff but, works Amazingly well.
I’d say pick your favorite brand and get that.
If you ever get a new plotter..it’ll match and likely network easier.
I’d recommend Garmin.
Yes, it could. Or it could be several other things.
With any heating issue, it’s best to start at the water and work inward after checking the obvious coolant level.
Intake clear?
Thru-hull.
Hose.
Strainer.
Oil cooler.
Seawater pump.
Trans cooler.
Heat exchanger
Exhaust elbows
Hull exit.
Along...
I’ve been down this road before....
What your hearing could be the damper plate but, is more likely gear teeth clash in the trans. It’s a known phenomenon and is harmless according to the tranny manufacture. It’s only on one side because of the extra internal gear to reverse the prop shaft...
Use OEM parts.
You have two choices, the ceramic coated or the E coated.
I buy the ceramic but, believe the E coated are fine..
Replace the elbows and gaskets every 5 years without fail.
Replace the manifolds every 10 years even if cooled with antifreeze.
Check the mounting surfaces are flat...
Last years dock rash from a deflated fender in a wind storm vs screw head holding fender to dock!
Didn’t do this repair myself due to timing/wx/launch day.
Looks okay for my ol’sled.
Filler then, Spectrum gel-coat to the rescue..
Well, the inexpensive Rustoleumn stuff worked great!
I just prepped the running gear for this year and the stuff adhered very well and almost zero barnacles..the prep for new paint was easy.
I’ve never felt threatened, attacked or uncomfortable while participating in CSR. I do not like the direction a lot of things in the world are currently going but, let’s leave the CSR alone..
I helped my dock neighbor replace his backend on a 1995 45 dancer diesel Westerbeke. Same process, got it done in the ER. I removed mine to make it easier.
