Preluber for the last 10yrs... Not needed, but it sure is handy for priming a motor that has sat for any lenght of time.
I use the preluber everytime I start the motor.. Maybe for the next ten I wont use it and see if it makes a diff.
I know a lot of guys dont, but I know of instances where they should have. Then of course we are a proud lot and most guys wont tell you when their stuff breaks..

Pre lube seems absolutely a logical and good thing to me. After sitting 3 months, it has to be a good for the moving assembly !
I can't understan why more are not in use.

I must agree with wobble. I've hit my pre-luber with the valve covers off and have seen oil. Not to mention I've been using my pre-luber for a couple of years and the two times that I've had to tear down my motor the bearings have looked great.
Just my two cents.....

I do not know if you need them or not, but the man that builds the motors for our race boat will not let a new motor he build leave his shop unless you have one on board.

If you've ever disassembled a properly built and maintained marine engine that was run within it's intended parameters you'd notice an almost total absense of wear.
I just took apart a 330hp 7.4 with 1300 hrs, many at WOT and was absolutely amazed at the the almost total lack of wear. Good oil, changed at proper intervals, and it just didn't matter that the boat sat a couple weeks between uses for 13 years.
The only time marine engines wear out is when they're spun too fast, run too hot, or other high power stuff. There's really no startup wear.
Prelubers have long been one of those "can't be a bad thing" add ons. I'd say in a marine invironment with good synthetic oil they've got to be close to useless. Oh yeah, and if you're too cheap to use a good synthetic, why are we even talking about a preluber.
But like they say "can't be a bad thing", and they're certainly less expensive than a lot of other stuff we put on our boats
And if you get the right kind, they make oil changes faster.

Every motor I 've ever taken apart has always still had a film of oil on all the bearings. Motors that have sat months before tear down.
I'm not to worried about the motor that sits idle for a few weeks. Between the oil film and the couple sec delay for pressure to register at startup, not sure I will ever have one.
Bottom line, can't hurt anything though.
