I have a 290 duo prop leg and have just started having a problem with the trimming it will come up but wont go down to get it down I have to release the hydraulic fluid once this is done it goes down.<br />Today I have power coming up but no sound from the pump to go down. So again release fluid stand on the leg and it goes down again trimming up no problems any one had this and what fixed it<br />?<br />Many thanks Nick
