Look up redbay on ribnet and it will also bring you to simillar discussions.
Define your needs, meet with lots of other ribbers, go for spins in lots of other boats, have a think about it, bring some experiened ribbers for a pint, go for some more spins(cost nothing and most ribbers are only too happy to help others) redefine your needs and only then go shopping. Form a relationship with a good marine mechanic!!!
Some boats slap because their under water profile is flatter than others. This often helps them to plane easierbut they are not as good a sea boat as deep v boats which carry the v shape the full length of the boat.
Honda engiine mentioned is good but heavy! check the power to weight ratio of some of the others. Whilst very good for its day i think the Honda design has been superseeded. I had a Honda 50 hp some years back and it was very reliable and quite economical.
Yamaha are my favourite engines.!!!!!!!!!!!!!!!!!!!!!!!!
Happy boating.
