Make sure you get the motor mounts for the 3Ym30, very important. I installed new 3ym30 in winter of 2004-5, and have 745 hours on her, only problem I had was over heatung issue which had sea weed blocking the inlet of the heat exchanger. And yes had a strainer, but now I have two of them. The weight of our boat is 20,000lbs, being a deisel mechanic I'm happy and impressed with the engine.
