You havent seen porpoising till you've rode in mine. And for the record, the only thing shims do is allow more negative trim to make the engine push the bow down more and create MORE drag. Its an awfull band aid fix for a real problem. I still need to run mine again, but I put a permatrim on mine. I want mine to run properly, not with the engine plowing to bury the bow. A properly set up boat should run level with the engine nuetral trimmed or slightly negative trimmed. What happens if you raise the jackplate when its porpoising? Sometimes the engine is mounted to low, and causes it. The powertech scd4 is regarded as the ultimate anti porpoise prop by most, and has worked on quite a few CAROLINA SKIFF'S. It's an easy to tirn semi cleaver design. And the holeshot with them is out of this world. Give Ken at propgods a call, but I bet he reccomends a scd4 in a 17 pitch, and if you buy through him, it's $35 plus shipping to swap props.
