Hi, I'm in the process of installing a heater on a 2000 Xstar with Indmar 350 engine. From looking at some other threads, the normal, location to tap in to the hot water is on top of the engine. As can be seen from the pic here, both are being used already.however. I need to tee one of these to add the hose barb or try another location.
The second pic shows an Allen headed blank that I am thinking I can use, wondering if anybody can confirm. It is on the port side just below the temp sender. Any thoughts?
