I do...I found it is best to do all of your other items first i.e. fuel treatment engine fogging then working on the raw water components remove impellar remove zinc anode on heat exchanger and drain remove hoses on transmission cooler ( raw water hoses only) then the exhaust manifold hoses they have a garden hose connector it is on the starboard side by the oil dipstick. I may have forgotten something I will check my engine out tonight after work and repost anything else... I'm sure someone will come along and add to the process.
