    Default Bowl lube....grease or oil??

    I'm sure this has been hashed out, but now that I have my pump apart and can see what's going on ...it makes me want to go back to gear lube instead of grease. What's your preference??? I just broke off the brass plug opposite the zerk, so a drill and a tap later there are shavings in all my old water soaked grease......It's not pretty.lol Any suggestions on that mess would be appreciated also. Oh fwiw it's a split bowl berk I working on.

    about a month or so ago there was a thread about this, If I remember ...they were saying don't greese um, it will wear the shaft. but that's what A.T. tells you to do. A few friends of mine just pull the plug and run water with no problems.

    I mean the plug in the nozzle... the (at least mine) plastic one that you can see if you look into your diverter. but that's just what I have heard, I dont go that route. as of now I'm running a mix of 80-90 with a bit of Lucas to thicken it up a little.

    I may be reading your response wrong, I'm just a lurker. but if you have your bowl off you can see that there is a crevice between the 2 bowl bushings, and on the outside of them is a bowl seal and a plug ( on the nozzle side). when you put grease, or oil, in your bowl that's where it goes. I dont know if guys running water pull the seal out or not. I'm sure some will tell me I'm wrong tho. Ill go back to drinking and lurking now.

    Berk = Heavy gear oil. 90w

    After every trip I force the oil/water mix out and put fresh in just to be on top of it.

    If you put grease in you'll end up forcing the seal out before the grease comes out the opposite fill/drain hole. Don't use grease on a Berk bowl.

    We initially designed our Bowl to be a Oil Lube Like Berk... After look at the run of Average We decided to change to a Lube system.... Dominator Runs a Dry Lube system which has major short falls in brackish water. So Roll The Dice on which system to follow...

    Default pump

    You can eliminate running oil completely, remove the seal & throw it away, you also have to remove the large cone shaped plug & throw it away as well, the plug I am talking about is on the opposite side of the bowl where the very end of the shaft is, You use a massive screw driver to remove this plug. With this done the water will lube & keep your shaft cool at the same time, you don't worry about sand or debris getting logged between the bushing & the shaft. Many peeps do this modification.

    My boat was setup this way when I bought it, I havent had any problems with it so I plan on leaving it that way.
