I'm going through the same process you are planning. My pads are steel, with carpeting on them, Probably not a great idea as they retain water too. See if you can find some grooved belting. It will work
As for the engine, Mine was winterized and sat for 5-7 years. When we went to start it up, the mechanic
spun her over with the compression
levers depressed for a couple of minutes, then let the levers up one at time. She fired right up and ran smoothly.
However, after running for about 40 hours, the rear main seal let go. Dried out over the years and never recovered. Perhaps turning it over regularly will prevent that from happening. I would say cranking the engine over manually every couple months might be a very good idea. If you are taking your batteries out and don't have a manual crank ability, bring your car along side and use booster cables
if you can get long ones. Alternatively, you can rig a gantry on deck
and haul your battery
up via a block n tackle.
As for major corrosion
below the waterline, We don't seem to have that problem unless there is damage to the paint
finish. My boat
is 34 years old, and has multiple layers of bottom paint
. Very little rust, but I too will be wet blasting her both inside and out. I have more problems inside because of poor layout of the furniture and lousy loose insulation
Have a look at my blog, It may give you some ideas. URL is below in my sig.
