I would appreciate hearing about any experiences or thoughts on these systems. Do they actually reduce start up engine wear in a meaningful way? Do they justify their expense? Thanks in advance.
I put one in the first year that I had the boat but took it out the next year because it was a pain to change the oil. I refreshen the motor about once a year (every 100 hours or so) and I didn't see any difference in wear between using it and not using the pre luber.
