Hey folks, I've got a bit of work to do on the injectors, and it'll still be 1.5 months before we have access to running water at the club. I'm wondering about pulling the impeller and running the engine for a few minutes with no raw water. I suspect the engine itself will be fine, given that there is still coolant in the fresh water side, not to mention it's -10c here. My concern is melting the aqua lift muffler. Any thought or experience with this? I understand it's frp? How big a risk is say 5min of running with no water cooling the exhaust, on a cold early spring day? I'd like to get the work done now, rather than rushing right before launch.
