Dewinterizing

Hello. We recently purchased our first boat; a 1999 Ski Nautique Open Bow. We are trying to get it ready to put in the water. When we purchased it this winter, the dealer winterized the boat for us. Can anyone provide some insight into what is required to 'dewinterize' the boat? We called the dealership and they can certainly do it for us, but the service technician that I talked to said it was basically just putting some 'plugs' back in and running some water through it. Is this something I could do myself? Any help would be greatly appreciated.

Thank you for the response. I'll give it a try. I'm assuming that if a proper winterization was done I don't need to do an oil change?

This is a great opportunity for you to start your own maintenance program! From here on out you will know when all the work is done on your boat... No more guessing.
Check you receipt for the winterizing some places do and oil change as part of the process, if not then the beginning of the season is a great time!
There will be a drain plug on each side of the block and one on the U shaped metal tube on the front of the engine. A little never seize on the threads and your good to go. Check that all of the hoses are tight, and the water strainer is spun on and tight
A new impeller for the raw water pump is a must! Don't take anybody's word on this! It's the best money you will spend on your new boat. A no good impeller can cause a major over heat and allot of damage in a,short amount of time. Learn how to swap a new one in now, save the old one as a spare, and replace the every 2 years regardless of how it looks! Cheap insurance.
Hook it up to a hose or use the bucket method and fire it up! Check for leaks, then head for the lake!
If possible try to tackle the maintenance yourself, you will get to know your way around the engine and if there ever is a problem you might be able to fix it and get back to the ramp!
Good luck! Ask questions! We're here to help!
