>From everything I have seen, the Beta Marine engines are a great option. One of the biggest problems with engine replacement is getting the bedding correct. Beta addresses this by designing mounts that are designed to be like for like with popular counterparts such as Yanmar and Universal. From what I recall the price is about half that of a Yanmar and without the cost of a re-bed the Beta is very competitively priced. I have a 30Hp Yanmar 3HM35F in my 37+ (40 ft) and often feel like it might be a little anemic. I would avoid turbo charged versions if at all possible.
As for a feathering prop I have one (Max Prop). I like the engineering but if doing the annual maintenance is something you would rather avoid then a fixed prop might be a better choice. A fixed pitch prop requires a transmission that can freewheel/waterwheel or has a shaft break. Check with each manufacturer. The nice thing about the max prop or similar is that if you find that the boat is over pitched or under pitched you can adjust (not on the fly). The new max props can be adjusted by a diver in the water, older style require a haul out.
