Hi, does anybody have any pics of the feed and return line to the heater on a TBI 310hp engine pls? Assume the return will be on the up stream side of the raw waterpump, where is the pickup for the hot water on the engine pls?

Search "y-tube" and you will find a pic of the return connection. You install the y between the thru hull fitting and impeller housing 'y' upside down. You can buy the y tube on skidim.com

The hot should connect to a plug on the block next to the thermostat housing
