Re: Bent shaft

You could get some miles out of it by babying it. There may be a buncha vibration,and the seals will therefore fail much faster. The light prop will help.<br />The best scale to judge on,would be lube condition after each trip. Buy a pack of pipecleaners from the drug store,a 5pack of vent screw gaskets,and check it thru the "vent" screw hole (like a dipstick on oil). If it's milky, like a peanutbutter milkshake left in the sun, the seal has failed,and is due to be torn down.<br />You will quickly get an idea it's ok if, after you ran it a few times,and still have no water in the lower end, that it's probably<br />best to "run with it". Good luck with it,and tite lines.<br /><br />------------------<br />the Early bird get's the worm...So, he don't have to stop for bait.
