Want to build an 8' hydroplane with my 13 year old. Looking for an
outboard 10 hp (the law for him). Want to keep it cheap if possible.
Any recommendations? I see lots of talk on here about motors I know
nothing about. Are there any books, websites, magazines that I could
use to learn something about the technical aspects of go fast motors
and making stock outboards go faster?

Thanks for any advice.
