I recently purchased two Masterlube Industries pre lubers for my boat. They seem a very logical addition to me. If they are as great as I believe them to be, why don't more people use them ? Why not everyone ? They're not really expensive. I also use Alysin oil. No one on this board seems to be familiar with it at all. All the piston aviation guys know the name well.

Just curious for input.

kind of interested in prelube myself; always my understanding that a disproportionate of wear occurs in the first several seconds of start up; more of an issue in boats that aren't usually fired up every day (Florida boaters excluded). let us know how it works out. -jeff

i believe that they dont hurt anything and do help. i've installed more than my gfare share.

I went with an electric Pre-Luber. I figured I may as well go electric for its versatility to be used as a pre-luber as well as an oil changer. This pump will empty my 12 quart pan in no time. Beats the hell out of sucking the oil out.

I have the standard accumulator tank style. I think it works. I know I store about 60 PSI when I shut it down. Has to go somewhere when I turn it on right?

I`ve always wanted to install a pre-luber, but have never stepped up and done it. I think for me, it`s probably the cost that`s held me back. They are about $250 right ? I can always think of other things to spend $250 on ...

I have built many, many engines over the years and have always wondered about pre-lubers. The fact I l always come to though, is that I have had absolutely no problems relating to lubrication issues ever. If an engine is properly blueprinted, I see no advantage to a preluber set up. I have torn engines down after years and years of service to do HP upgrades and have yet seen a problem in my case related to oiling. imho.

ghittner I see no reason whatsoever to doubt you in any way. However, I still believe in the basic concept of pre lubrication. I don't know what the typical engine build you do is. I believe most boaters don't need maximum output 100% of the time. Most go for long term reliability. I believe pre lubrication will aid in achieving that goal.

It would be difficult for anyone to prove to me that having oil everywhere in my motors prior to turning them over even once is not a good thing.

Thats another misconception. People think that when they prelube that ALL internal parts have oil. Not so. The motor would actually need to be spun over while prelubing in order to have oil threw the crank, up to the cam bearings threw the lifers then pushrods and rocker arms while bleeding off at the timing chain and clearances. The preluber is designed to make sure the oiling system is full and the crank has oil at start up.

But I do use them!

I bought my boat with them already installed. A couple people have told me to remove them. Since they are there I use them, but I don't think I ever would have installed them.
