Hey guys I have a 84 Larson delta conic with a Volvo Penta AQ 125 and the 280 Drive problem is when the boat is put in gear the lower unit will lower it so down to normal drive this is very frustrating especially in weedy or shallow areas not exactly sure where to look any help would be appreciated thank you

I take it this is a tilt/trimmed engine. If so, it sounds like you have either air in the tilt/trim hydraulic system. or a seal with some leak by...

The Aq125 would have most likely come with a 270 outdrive. Either way, they both had the same mechanical tilt setup. You're going to have to inspect the tilt assembly to determine the cause. There is a clutch system that is adjusted by tightening the upper cover of the tilt assembly, under the black box.

I would look into tightening the housing a half turn to see if you can keep the drive up better.

Have you read the manual? Sound like it is working properly.
The drive should go down if you push on it, same as motoring with it halfway up. Pretty sure the drive is not designed to be used unlatched.
