Matt, I had my transducer installed by a marine electrical company,due to it being covered by an insurance claim. I have installed a few transducers and it is pretty straightforward. With the forward scan you need to locate it down as low and forward as possible and of course the transducer needs to be installed absolutely level by contouring the plastic shim to fit the hull , of course it needs to face absolutely forward.
Having said that, I will now say if I had to do it again , I would have saved my money and not installed it. Maybe it is just my experiences,but I find the images so erratic,to be useless. I thought it was because of the soft mud of the Chesapeake affecting the returns, but I am now in the Bahamas with packed sand and the returns are still useless. I wish it worked well here , but it does not and I don’t even turn it on.
I have spoken to the B&G reps. At the Annapolis  boat show the last two years,even showing them videos of the erratic display. They had no explanations, when I asserted that they would not sell a product that is useless,would they.
I hope you have better luck than me, most everyone does, in any circumstance. I have the Luck of the Irish,but not the good type.
Good luck,

Mike & Eric,

You have figured correctly.  In the method I used the epoxy is ONLY inside the foil, not overflowing into the collar that connects the foil to the gearbox.

Anytime you need to get epoxy to lose its grip, apply heat.  Most cured epoxies begin to soften at relatively modest temperatures, usually below 100C.

Hi Mike,

Thanks for your correction .

I see what you mean. 

Seems Bill did it the right way and the previous owner of ABAYOMI ( Nathape) not .

The manual gear box is still doing ok so I guese I will have to have a collar pre machined and once it comes up change it the right way.

Cant think of an other way right now but if you have a solution do not hesitate to jump in.

Here a photo of the situation.

Took out the lower bolt but the top one and collar would come out. You can see the epoxy on the top edge of the collar. 

Did not want to force it as all appears ok and someone told me if it is not broken don’t fix it😂 

Only wanted to check and pre maintain the 

Manual gearbox.

Hi Eric,

Bill's method has the bottom of the foil taped to hold the epoxy while it cures. Only after the epoxy cures is the foil put back into the collar and bolted in place.

If yours was repaired in place, it is possible epoxy has bonded the foil to the collar. I'm not sure if there's an option to separate them beside the procedure you've outlined. I will think on this. Maybe someone else has an idea.

Hi Bill, 

Have been reading your weblog about your repair solution of the main foil collar filling  with epoxy.

My question would be what to do when you need to overhaul your manual furler gearbox? 

We own now ABAYOMI since June last year and found the previous owner did the same you did and filled the collar with epoxy. 

But this means we need to cut just above the collar to be able to get the manual gear box off when we want to replace the seals and O rings in the manual furler gearbox . This would mean I have to machine a new custom made collar as Amel can not supply those anymore.( I checked last month with Maud)

Do you have the same situation now or did I mis read the way you did it? 

I my opinion a half round bar filler in the foil would be a good alternative. 

Best Regards,

This is how we did ours. http://fetchinketch.net/boat-projects/amel-mainsail-foil-repair/  Come back to us in another ten years and we'll let you know how long it might last, but after three years, it is still perfect.  A LOT cheaper than the Amel kit, although that should be a very minor consideration for such a critical part.

The Amel kit either wasn't yet available, or just a well guarded secret when we did our repair. The kit from Amel looks to me to be a LOT more robust than the original design, but if I had to do it over again, I still would do it the way I did.

For anybody needing to do this repair, I would STRONGLY discourage just drilling a new hole and calling that good. The foil does not have enough thickness of metal to transmit the torque from the motor via a single pin without very rapid wear.

Michelle and I are preparing for haulout in a few weeks, and intend to install a B&G Forward Scan transducer while out of the water. 

Question: Does anyone have any knowledge to share on do's and don'ts from your installation?
