Follow up - after Thanksgivings:
I really thought the access to the engine was easier than my Carter 33... not really
But I did the filter and oil change through the dip stick - OK
But, I did manage to check the impeller - OK !
I did manage to unblock and open/close the blue faucet the the water intake. - OK !
I removed the hose at the faucet, , dunked it in a 3 gal antifreeze and started the engine... Aaarhhh - no fluid was pumped, no suction on the tube, no spit through the exhaust and the manifold got too hot too fast. I immediately shut off. So, my Lady it is still not winterized.
What did I do wrong? Is it maybe because I had an air-lock in the tube?
For my westerbeke, I had gone to a 2 days eminar by Hansen Marine. does anyone knows if Volvo offers something like that ?
