Need some advice on what type and where to install a water pickup. 23' Tunnel boat Stern Drive. Need ram pressure fed pickup for the intercooler and oil cooler. Do not want to rob that much from the sea water pump. Even if we did, would need a bigger pickup.

How about some been there done that advice?

if you have trim tabs you can pick water off of them. if not then get a thru hull fitting and take the water from the bottom of the boat.
