Where is the best place to connect the water supply line to the supercharger water intercooler? Currently its has a tee fitting on the hose that goes from the outdrive to the seawater pump...

most run a 2 stage sea pump,

I run two independent pickups and dump lines for the inter coolers

Separate thru hull pickup

resurrected - are you pickups through hull as well?

Yes they are, the set up is new to me this year. In the process of reassembling, so no actual results. The reason I went with independent pickups instead of 2 stage pump was, at idle a cold inter-cooler can cause fuel to condense.

Sales staff at Teague advised that I shouldn't need pressure blow off valves at the 80++mph top speed I am hoping to get to

If you live in a hot climate area, you may want to push water through it all of the time so it doesn't detinate after idling for any length of time.

Mine are plumbed off the sea strainer.

Multiple ways of doing it but as mentioned above climate and water temps have a lot to do with how you want to plumb it.

mine idled like **** at ROTO with full time water going thru the cooler. I added separate pickup . and a drain so water doesn`t sit in them when not in use
