We just pulled these riser's. Stored the boat in fall of 98 It was running fine. When we launched it this year the engines were gone. How does this salt water get way up in the risers like this. Valves rusted on center cylinders. engines probably gone.

Best to start a new thread with your questions BOATLUD.
Not a good idea to just stick your question on the end of a year old post. Very few will see it.
