Took the boat out yesterday - glorious 50NM on the water. Going out and coming in, engine easily got up to 2100 RPM. Today, on a solo run, engine cranked and started normally. Got out of the slip and gave it fairly high throttle and it wouldn't go above 1700 RPM. The engine didn't sound like it was firing on all three cylinders (Universal 3-banger in a Pearson 37). Looked over the stern and saw black crap in the water. Returned to the slip.
After tying up, opened the throttle wide (no load) - got about 2000 RPM, still putting black crap in the water. Shut the engine down, checked the oil level. Normal. Any ideas? Tks.
