transducer question.. airmar p66

[simonpp82]

I have a furuno fcv 620 with the standard airmar transom mounted transducer. I'm having trouble with it being knocked out of its "locked" flat postion every time i hit a big chop at speed or catch a little bit of air (both fairly common offshore obviously). I'm aware that this is a design mechanism that will prevent it from being snapped off if i hit something, but I'm getting really frustrated because i can rarely get a reading at planing speeds offshore. Has anyone had a similar problem and fixed it? I thought about super gluing it in place but i don't know whether this is a good idea. So you know, it's mounted on a haines signature 542 and the bottom left corner of the transducer is about flush with the hull just like it's supposed to be. It also sits very flat (the back of the transducer isn't protruding to far), any help much appreciated - Simon.

G'day Simon

Bit strange mate . I run the same transducer and it is well below the hull to get clear water and so would have more load on it . Never had it kick up . Maybe have another look at the install pics for the x'ducer and make sure it is right . The little tab in the top helps to lock it from memory as well .

Mine does the same thing as yours simon i was going to put a dab of sika on it.

Thanks Hagar..

I did go over the installation instructions numerous times and i'm confident that it's been done about as good as it could be.. It may just have a weaker "lock in" than yours? It is good to know that it's not normal though, hopefully i'll find an answer

[simonpp82]

hey jimbo..

Frustrating isn't it!! Where u gonna dab the sika??

[jimbo59]

just under where it tilts up just in case it bumps somthing it will still come up but it is only a band aid job.

[simonpp82]

yeah might be the only option?? I'll give it a go too and see how it goes

Mine was doing the same thing also, until the little ledge that it locks with broke off completely.......................( pretty crappy design really )
Now it looks REALLY dodgy, a pile of duct tape seems to hold it in place, but far from desirable.
Hopefully Airmar can supply another lower section of the casing when I get around to chasing one.

Try using some heat and bending up the locking flap. Apply the heat evenly until it starts to bend, it should tighten it up nicely and lock in properly.

Mine did exactly the same thing,good luck with the sika,that lasted two trips for me,I ended up pop riveting it right through the two sections and supa glueing it as well,hasn't budged since.......I do have a spare one though for when the inevitable happens.

It looks like the knerling on the plastic isn't aggressive enuff to stop it from moving

I put a a tech screw in each side perfect now.

G'Day,

Mine did that once also, out at the Banks, lateish in the afternoon, middle of winter, guess who had to go over the back to fix it? not easy or much fun in a pitching boat!

As other have said, I just put a small amount of silicon on it then locked it into place, hasn't come up again.

Stick a self tapper screw into one side of it, but cut the screw off so that it will break away if the ducer hits something solid.

mine did the same thing, very frustrating

cheers

Mine does it as well when I get some air offshore. I use the gaff handle to click it back down. Very annoying
