  • trim tab hose clamp?

    Its been 3 years since the last time i replaced the hose and no surprise; one was leaking this fall. I found the leak, again - no surprise at the edge of the rusted clamp that holds the hose on the tab's piston.

    I have spare hose from the last go-around but no clamps. Any reason why I can't use a 1/2" hose clamp instead/ That will allow me to back it off and replace it annually as opposed to waiting for it to rust out and cut into the hose.

    Larry- I replaced one side with SS clamp, no issues after a year. Planning on doing the other before launch. Just be careful not to tighten too much, it would be possible to break the barb.

      next question

      swapped out the hose today/no issues w/ the clamp. REfilled the reservoir after the hose was on.

      The boat is on the hard, unplugged, battery state is questionable.

      When I went test the tabs; the motor whined and groaned; Dytek temp gauge on the dash went bonkers which is a sign to me of a voltage drain. Neither tab budged; either up or down.

      There were no leaks.

      I'm happy to push this off a month till the boat gets recharged fully and test again at that point - other than hose leaks, can anything go wrong w/ the tab system or motor that I should look at before I splash in 6 weeks?

        The tab system is self bleeding and may take several cycles to get to the point to re-establish the oil level. One thing I have learned with marine hydraullics is that they hate the cold. I would suggest getting past this freezing weather before trying again. Then with a fresh battery/shore power cycle them a few times and refill to level. If you can find a 50 degree weekend I'm sure this will work out for you.

          you mean ATF isn't supposed to flow like honey ?

          duh - stupid me; the fluid in the hose was so cold soaked that when I took the reservoir end of the hose off I was able to turn it upwards and only spilled a few stringy drips.

          Last time I did this in mid summer it was a mess!

          I suppose i can wait a few weeks till it warms up and test then.
