Anyone know if there is a procedure for bleeding air out of the lines on a K-plane?

Noticed one of mine drooping and spongy over winter storage. Cycled it up and down a few times and seemed to correct it, but a few weeks later it was drooping and spongy again. Not sure if there is an air pocket in one of the lines or if the cylinder is bad. Any ideas?

Usually you bleed the air out by running the k-plane up and down a couple of times. But if it creeps down,may have a problem. Could be a lose hose, check valve in the trim pump(dirt under it or debris),or oring/check valve in piston. Best bet is to put Merc's hyd. test guage on the pump and check the pressure/bleed down rate. Make sure the lines aren't backwards to the trim pump too (found one like that once).

Marinetrans,

Thanks for the suggestions. Reversal of lines is possible ... I bought the boat used without power so several people have wreched on it before me and I have had little time on the water before putting into winter storage. Will check out your other suggestions as well.

Sincerely,

Chris
