I have only had my Nissan 18hp for two years now but what I have done and what is recomended in the Manual and by Marine Products is to:
1-Change the lower gear oil.
2-Run Stabil though motor. Then drain any left over fuel from Carb.
3-Change oil and oil filter.
4-Change Spark Plugs.
5-Run fogging oil in each cylander.
6 Store motor vertical (Leave on boat) and wrap with a motor cover and a tarp to protect from the weather.
