I owned a 1985 Outrage 18 for 5 years and used it in the waters around Vancouver Island. It handled great with the original Johnson 150 (about 400 lbs) as well as with the Suzuki DF140A (about 410 lbs) I repowered it with.
However, when I added a 110lb F9.9 to the transom for fishing trips, I could really feel the extra weight on the transom and didn’t like the boat as much. I would opine that while the boat can handle 600 lbs, I think you would like it more with a lighter engine. There are some good choices in the 115-150hp range that are under 500lbs.
