Simrad tp10

[thorJ30]

Hi
I have a tp 10 selfsteerer for my j 30 ...

that silly thing seems to work ok. for about 3 to 5 minutes... than it starts to pendle more and more, until very shortly thereafter it gets itself totally out of wack. An audible warning tells me that we are now going in circles...lol

Any ideas ?

p.s I am on a lake with almost no wakes, it does that crap under engine or under sails ..

Thanks Thorsten
