I know every inch of storage is important but make sure you always keep one onboard and a spare nut and pin. I keep 5 pins and two nuts. When you can't get to the bank to change its not hard to drop the nuts and pins in the water while changing. In the summer taking a swim to change usually is very easy but hanging off the back of the boat is a job in its self. I rig my landing net in a rod holder off the back corner positioned under the foot. If you have large mesh or torn net. You still have a good chance of recovering if you drop any thing. Even dropping the prop is very easy to do. You can find kits with cases in the hundreds with the wrench and all but I like my extra room. A prop for a 115 in a case would fill up my whole storage compartment. I found an old transon mount trolling motor bracket and I am going to build me a mount for my cheap aluminum spare prop to mount off the rear of side of transom. and find a thick cover maybe something with a tie string or elastic that will cover the sharp edges.
