Winterizing tip to prevent cracked blocks
Today, 08:57 AM

This only applies to those equipped with single point drain systems. This is the 3rd boat that I have found the block drains "blocked" with scale.
You MUST remove the quick connect hose and probe the engine block drain holes .
Failure to do this critical stem will most likely result in a cracked block. This also applies to those who have a flushing attachment hooked to the block drains and manifolds. You need to remove the flush hoses to make sure the connections are not blocked by scale.
In fact, it may be to your advantage to completely remove this system and install brass drain plugs.
