Here are the items I go through each spring when I bring my boat out of storage. Some of this may not apply to you and as a FYI: I have a 2 stroke outboard. Please comment below with anything I missed as part of your procedure and I’ll add it to the list.
- Check the trailer lights
- Jack up trailer, verify wheel bearings are solid and grease as needed. I use bearing buddies and highly recommend those. (Repack every other year)
- Inflate trailer tires to recommended PSI
- Inspect winch strap and winch functionality
- Torque lug nuts
- Remove rodent/mice prevention (Moth balls, dryer sheets etc)
- Visually inspect wiring, gas lines and oil reservoir.
- Ensure batteries are charged, mine are connected to an onboard charger that remains plugged in all winter
- Quick check bilge pump operation by switch
- Check/Replace fuel/water filter if equipped
- Place motor muffs over lower unit water inlet screen with water running and start motor. Let motor run until thermostat opens and fogging oil is burned of.
- Remove, clean/replace spark plugs. Keep the original spark plugs for a backup
- Make sure you have your drain plug and a spare ready to go
One of the most important pieces from this list in my opinion, is ensuring your motor starts. Ok, all of these points are important to a degree but using the motor muffs / rabbit ears / motor flush kit or whatever you want to call them is the easiest way to ensure you’re not “that” person at the boat launch.
