Hi BBP! Nope, haven't run her on muffs yet this year, this damage happened in the fall when I was winterizing her. I was running her on muffs, the muffs slide down just enough to run her dry! I thought I caught it quickly because the engine never got warm, but long enough to toast the impeller. After this debacle, I bought a pair of Mercruiser muffs with the steel pin that runs through the drive, I won't ever make this mistake again!Big Block Power wrote: Wed Apr 29, 2020 9:32 pm Unreal. Did you run it on the muffs this year? That's one thing I like about Volvo is no muffs needed.
Check your pwr str cooler and T stat and cool fuel and the bottom coolers under the exhaust manifolds.

Re: Impeller Replacement
Hi A7! I had Greene Marine in Wilmington NC change the impeller, I'm going to flush the raw water system myself to get the impeller pieces out of her!AsLan7 wrote: Wed Apr 29, 2020 9:22 pm .
