Boat Maintenance and Repair Kits

Curious to know what guys carry on the boat with them or in their trucks in regards to maintenance or repair for your boat/trailer. I'd love to come up with a comprehensive list of the items that are "must haves" and "nice to haves" and share it on WAFISH. 

I had some issues with my trim this weekend and found my self in need of a spanner wrench, snap ring pliers, and some power trim fluid, probably not necessary to carry on-board the boat but would be great to have in the truck. I'll have them next time around for sure in addition to the items below I always carry:

• Phillips and Flat Head Screwdrivers
• Crescent Wrench
• Prop Wrench
• Spare Cotter Pin 
• Small socket set
• Needle Nose Pliers
• Electrical Tape
• Zip Ties
• Spare Trolling motor prop and hardware

So what else are you guys, tournament fishermen or not, carrying when you head out on the lake for the day or weekend?
