Hey everyone, I just bought a boat for the first time ever it is a barette open bow 19 ft it has a penta Aq131a 275 Volvo outdrive I have a few problems when I took it out for first time first thing steering was very easy out in nuetruel but once in gear pulls completely left and steering gets very hard to turn ??? Also when I went to take it out of the water I could not get my tilt up even one person in water lifting while one pushes tilt up I had to take a but off hit the bolt out that runs horizontally through the out drive at the bottom it freed then tilt took it right up works up and down until it fully goes all the way down then it latches around that bolt ????

On the 275 drive, the exhaust outlet housing serves as the trim fin/torque tab. It is rather small, and does not do an effective job at it, unlike the 280 etc.
If the boat pulls to the Port side, you'll need to adjust the trim fin/torque tab to Port.
Loosen the center bolt and make an adjustment.
This will help remove what we call prop wash steer torque.
You will not be able to correct it for all speeds, but it will help.
Keep adjusting it until you get it correct for the speed that you cruise at.


Also when I went to take it out of the water I could not get my tilt up even one person in water lifting while one pushes tilt up.

That would be the "set pin", and it should be installed in the center position.
As you operate the Lift Out unit, the vice rod will extend.
As it extends, the vice rod pressure plate will contact the push rod thrust sleeve.
The push rod will depress the latch unit and it should release for Lift Out.
If not, you'll need to go through the entire system and find out what is wrong.

Correct..... if all is working, as the drive is lowered, the latch hooks will grab and hold onto the set pin.
The system is actually a "break-a-way" feature in the event of an impact.

"As it extends, the vice rod pressure plate will contact the push rod thrust sleeve. "

I'll add a quick comment, based upon a couple of hours of happily troubleshooting a similar AQ131/275 lift problem. Look carefully at the end of the vice rod and confirm that the "pressure plate" to which Rick refers is actually present and screwed tightly in place. On my rig, it apparently vibrated loose and fell off (after only 30 years of use!). When this happens, the threaded hole where the pressure plate screws in can encompass the push rod thrust sleeve so that it isn't pushed down against the hook assembly, causing the hooks to remain latched.

This is an almost unbelievable story. I ordered a new pressure plate and problem solved. The next time we went down to our usual launch and while waiting in line, I noticed something shiney sitting on the edge of the pavement; you guessed it - it was my missing pressure plate. Now I have a spare...

 
The vice rid pressure plate is locked in place by a tab washer.
When the pressure plate has been tightened correctly, the tab is then bent into a recessed area.

Hey guys is there any kind of schematic on what you guys are trying to explain to me so I know what I am looking at I have been trying to google it but can’t find anything on the it
thank you
 
Vice rod...... not vice rid!
sheesh!


Yes, I should have a schematic or a few images.
I’ll see if I can find them in the morning.

This will lead you to a schematic for the lift-out unit.

In this image I show how the vice rod's pressure plate contacts the push rod's thrust sleeve.
The thrust sleeve will sit "proud" of the suspension fork.
Prior to the pressure plate actually forcing the suspension fork down and raising the drive, it will first depress the thrust sleeve, which in turn pushes downwards against the push rod, of which releases the latch hooks from the set pin.
Once the latch hooks have released their grip on the set pin, the drive will be raised to the desired height.

What may appear to be overly complex, is actually very simple once you've had three or four shots of Whisky and have stared at it for an hour or so. ;)

By the way..... the lift out unit incorporates a clutch system that allows the drive to be forced down in the event of powering-up while the drive is in the UP position.
To test this, raise the drive up with the lift out unit.
Push down on the lower unit housing.
If the clutch is working correctly, you will be able to push the drive down and will see the latch hooks lock onto the set pin.

At this point, the pressure plate will still be in contact with the thrust sleeve.
You will now operate the lift unit (drive down) until the vice rod becomes fully retracted!
Once fully retracted, you will have the necessary space between the pressure plate and thrust sleeve, ensuring that the latch hooks remain latched.
