dump to the river....the side plugs on plate is used for dry stacking adapter plate....
on a 2 piece plate they would come down off port side ...tee...one returning to 2 piece plate and other dumping out as the tale tell.

You should have the two thermostat housings dumps teed together and dump to the river out back of cowl.
You need to run the merc restrictor washers with the rubber gromment from the t stats on them.
If your merc dealer can't get them and don't know what the part number is I can go to the garage and look at the package. I have a spare set.
The poppet hose will need to come out the cowl, but you will need to restrict it to keep from dumping to much water. You'll have to play with that to get restrictions. Right. Most people stick a small peice of smaller hose I the end till they see the temps and wp they are looking for.

What all did you change, just from 2 piece to one piece adapter?
Check throttle linkage obviously first!
