What is the difference between the Auto-Meter gauges that I can order from the Jeg's catalog that are available in both electric and mechanical and the Marine ones from Rex Marine and other suppliers???

I would like to completely redo my dash with these and Rex Marine says they are out of catalog's (yea right! they are always out of them when I request one)

Fred's has the cheapest and they look great just got some for a Canadian friend.

Trick Marine

Make sure they are the Marine version.

Differance??? they put an M in the part# and charge 20% more!!!

Dyno, that's what I thought!!!

I was going to figure out whice ones I wanted then give Fred a call!!

Don't try that with your alternator...

I don't know but when I bought my procomp gauges the salesman asked if I knew these were not marine gauges. I asked him to explain why the sell the outboard motor tach? No answer. They have worked flawlessly for thee years but they do live in a canopied cockpit.

constant exposure????put a cover on the thing!!!most of the race boats ran Autometer way before they made "Marine " gauges....take care of your stuff it will hold up.My .02
