Small leak, only when running

[BellevilleMXZ]

2005 5.7 GI-e SXM DP This leak started late last year. ONLY leaks when running, and is down at the very back, can see it drip down transom. Idle, barely a drip, if you tach it up, its a steady drip. Not much back there to leak is there other than y pipe? Kind of scary to crawl back/under there with it running at 2k! Weird it might be y pipe, as its a low hr corrosion boat/engine. I going to have a closer look, but not looking forward to it with it running.

Is your power steering cooler on the back of the engine? It might have a loose hose, or at the worst a leak. That's where I would start looking first. If the cooler is on the side, You might have a loose connection on the fresh water pick-up hose. Good luck Dave-R

Possibly the raw water inlet. The tube that the inlet hose connects to can corrode or possibly just the hose is bad. Power steering cooler would be up high and raw water inlet should be low. Both would leak worse at higher rpms. Good luck!
