clunk when putting into gear.

[Givener316]

when i shift into drive i sometimes get a jump clunk, like the lower unit bounces up, and slams back against the boat.<br /><br />dealer said that the hydralics are o.k., so what can it be?<br /><br />1990 four winns 180 horizon w/4.3L omc cobra

What is the idle rpm?

Either the trail out switch or low fluid in the hydraulics. Get a new dealer. Worse when you do from reverse to forward? When in reverse...does the unit want to screw itself out of the water?

the idle rpm is about 700. i know thats alittle high, and that proably explains my shift problem, i need to lower it alittle.<br /><br />it only really does it in forward. and going into reverse is fine, and driving in reverse is o.k. <br /><br />when the boat sits for a few weeks i notice that the lower unit drops alittle. but the dealer said that they pressure tested the system and it was fine. is there anything i can do on my own?

Re: clunk when putting into gear.

holds pressure on the cylinders when you're in reverse so that the unit doesn't "trail" out.
