I'll second what Andy said...... having a tower makes a huge difference in the usability of the boat. But if your not planning on keeping the boat, it might be too much.
Nate: The Globe impellers have a guarantee that you can run the engine dry for up to 15 minutes. I will usually start my boat for a few seconds to blow the exhaust & mufflers out so they don't freeze in the early spring or late fall. The Johnsons have worked for a year or more in the past. Just thought I'd check this one out. Google "Globe impeller" for more info.
Mike: No pics of the LEDs or disco ball on my own boat....... yet. We took a trip out to Banks Lake (central WA state) last year with some friends who have a 23' LSV. He had the disco ball but no LEDs. It wasn't out while we were riding but was a riot during the booze cruise at night. The LEDs should just make the effect even crazier. I picked up the 8" one for like $10 on Ebay.
