Leg Trim Again

[whisper]

You may remember that we had major problems with our 290 leg last year - in forward gear it kept dropping and the rams wouldn't hold pressure. In reverse the leg tried to climb out of the water.
Professional advice was to spend approx £1500 on a new pair of rams - pigs to replace.
Following other forum members' experience and their efforts to correct same problem, my colleague got the pistons repaired/repolished and then reinserted into the existing cylinders.
Cost - no more than £250.

Boat relaunched last week and problem seems to have been sorted. Well perhaps!!
When we set the leg at say +2 it will drop to 0 over a period of about half an hours use at speed.

Is this normal "troops"?

In a word, No. They should stay put wherever you set them - mine do.
Sounds to me like you may have a leaky valve in your trim motor, or a fluid leak. No doubt somebody with a more detailed knowledge of where the problem could lie will be along shortly.

Thanks for replying. Your answer was not what I wanted to hear - bu**er!!

Don't know where the rest of the "experts" are.

Our present situation is far far better than pre-repair. Then we even had to tie up the leg to prevent its downward movement, when on our drying berth. Now the leg stays up on its own, thankfully.

Along with the slow downward slide we now get a 1 point movement when changing from forward to reverse gear.

Hey Ho.

Are you sure it is dropping and not the sensor just skipping a "cog"?

Thanks,

Never thought of that. How can one check if that's what is happening?

Atleast it would appear that this year we can use the boat without worrying about using reverse , wandering into shallows or drying out.
