^^+1 - you don't need to over torque the the riser plugs, block petcock or knock sensor. Keep them oiled up. I just make these plugs hand tight and then an 1/8 of a turn and never had a leak. I have the graphite packing in my shaft log and my bilge is usually dry..depending on how long my friends stay on swim deck to drain a bit before re-entering boat.
If you dry block - oil or anti-seize... if you have money to burn check out the www.evaporust.com
- I spent $100+ and removed a bit rust.....may spend $100 to keep water jacket channels clear on my 1995...
