Rounding out the last step would be "fogging" or often referred to as "pickling" which is a process of coating your engines internals with oil. This helps to protect seals and rotating surfaces keeping corrosion away. While all of this is a methodical process it keeps us in touch with our boats needs.
Winter is also a great time to take your propeller and have it serviced or lab finished for better performance. Remember, dinged, and dented propellers are most usually out of balance. Unbalanced propellers can cause larger, more costly failures with prop shaft seals or other drive components. Companies like BBlades propellers offer winter specials and this leaves your summer to no down time having your prop gone as well as improved overall boat performance. If you do live and boat in the frozen parts of the country we hope you are planning your performance upgrades and using your off season wisely.
