It will be "accurate". Just "proportionally" lower. Just mark the zones on the gauge so the operator can understand whats going on. I use automotive decal vinyl around the outer edges of the bezel it sticks to the glass real good. Operators don't always read the numbers on gauges right. Anything important like oil pressure, coolant temp, pyrometer etcetera get some green, yellow and red so the operator can tell at a glance what his status is.:drink:

I know what you mean about operators not always reading things right. the more simple you can make it the better.

I used a tailstock and a special made splined adapter to make the connection between enginea and drive,I was thinking about making one from a solid plate ali
If I only knew where to buy one back then...

6LY series engine has a industrial SAE #3 flywheel & housing setup. Cummins 6BT has a SAE #3 housing set up and is sold in a sterndrive package with a bravo out drive:drink:

No Bling Bling?
 
It's looking like a good straight clean install..... Just a minor suggestion from the peanut gallery..... On the step on surfaces polished stainless steel diamond plate. On all sides and bilge 1 mm mirror polished stainless steel. It makes wiping up messes real easy and sets every thing off.:drink:
