Passarelle Upright angle

ah! I'd also check what oil is there. IIRC Bez expect iso30 hydraulic fluid and not ATF (but I may be wrong on that) tbh shouldn't make much of a difference as viscosity is similar...

When you lift it as high as it goes, you should hear a clunk as the cylinder hits its max extension stop and the pump motor should carry on running, possibly with a change in tone. The motor should not stop. (This is perfectly ok - it is ok to run the motor against the stop because there is a pressure relief valve). Can you describe whether this is happening, or what else is happening, exactly?
The motor continues to run with change in tone but not hearing a clunk (will tune in more to this next time though).

OK but if you can't hear the clunk of the cylinder extending to its maximum can you feel it hit the stop as a single vibration, if you put your hand on the neck of the cylinder?
Need to know whether it is extending to its design maximum (ie touching/hitting a stop) or if something else is preventing it from extending.
 
Apologies if I'm going over what has already been suggested but how about supporting the passarelle and disconnect the ram from the bottom of it and operating the ram without any load and see how far the ram retracts and extends and you can then have a close inspection to see if it's movement is being restricted in any way etc.

Yes, when they install them, they just tie a rope from the passerelle to the flybridge railings to support it
 
They weigh ( or our Pincraft did ) a ton .Be very careful, gets some big blokes and arco prop ready if disconnect.

We , the equivalent of a front row of a rugby team :) had to support it while I moved its adjustable fulcrum back .

v.heavy, and awkward. Got mine in place with a HIAB(sp?) and built a custom wooden ladder to support it after getting the pivot in place and before deciding the final position for the ram mount on the stern
 
Luckily my boat has its own crane (which I electrified with a remote control)..this allowed me to do the job single handed...but my passerelle is a lightweight aluminum one (but still heavy)
 
After some trigonometry calculation or my preference a scale drawing, can you have fabricated a stainless steel extension between the ram end and fulcrum. Needs a bit of design thought to make sure it doesn’t ‘flop’, maybe utilising the LHS hole to stabilise.
I‘m guessing now that it won’t compromise the horizontal position

I've only just seen this thread, but it all strikes me of an effort to find a solution to a problem that doesn't exist.
I mean, in my boat the passerelle probably goes a tad higher than in the OP boat, but surely doesn't stretch as vertical as in one of the previous pics.
Anyway, even if it would, I would never, ever lift it up to that point, for two reasons.
First, I can't imagine any situation where doing that would serve any practical purpose.
Second, and more important, the forces on both the passerelle hinge and the cylinder attachment are bound to be rather odd, both while lifting and lowering up to that vertical position. And the last thing anyone in his right mind wants is crack a GRP transom - which is very far from being unheard of!
 
P, I assumed OP wants to walk behind/under the passerelle in order to enter/exit to the pontoon on a bow to finger mooring - I may be wrong though.
 
Just a thought. If you’re still struggling getting it up you could try viagra ?

Sorry. Been reading the various posts and biting my tongue but couldn’t hold back any longer :)

I’ll get my coat (or most likely a bollocking from the anti-fun forum Police)

Hi guys

I'm new to the world of passarelles. I have a Besenzoni on my new (to me) boat and trying to figure out if I can adjust it to be more upright in it most upright position. The attached photo shows it in its most "upright" position but I've seen other boats where the passarelle points straight up thus allowing for better access on swim platform. Any thoughts on whether there is opportunity to adjust it somehow? Hard to judge if I'm at theax angle for the ram, it looks like there should be a bit more in it.

Many thanks

Just out of interest....if you put it all the way down would it hit the swim platform ?
 
Apologies its taken time to get back. Mystery solved, its at its max extension. I lowered it a bit then manually lifted and I can feel it hitting its stop/top of the ram. A bit baffling as the comparator boat (same model) has exact same passarelle with exact same brackets fixed in same place (to the cm). I guess for some reason mine got fitted with a shorter ram OR got replaced along the way (although it also looks identical)

I will run with it for another season, if it continues to get in the way ill remove it.

Thankyou for all the suggestions and guidance

What a pain in the backside. That said I've come to accept the 'hand made' nature of boats and two identical boats can have oddly different fixtures. I wouldn't be surprised if they happened to have a shorter ram version in stock when building the boat and thought it would be good enough.

Or the other boat got a longer ram by mistake
 
Placing a block of wood in between the base of the ram and the transom will raise the passerelle to a high angle...but make sure you have done your trigonometry properly or it might not come down low enough
