Message: <blockquote data-quote="Crazyboat" data-source="post: 498510" data-attributes="member: 21552">When I was a kid I bought a long shaft for my little tin boat, not realizing how it would wreck havoc on how the boat handled. My dad and I simply bolted a piece of 1/2" plywood to the back of the boat, cut her 5" above the old mark and filled in the gap with scrap wood. Painted the daylights out of it with (I'm sure lead) paint and dropped her in.  She ran like a champ and I never thought about it again, until the regular untreated bolts started to rust, so we changed them with galvanized ones and it was all good. If I was going to do it different today I'd built it taller and shave off as needed to peak performance. In your case add 3.5" of height and use a circular saw to drop her a 1/2" at a time until she doesn't cavitate any more.</blockquote>
