FF adhesive?

[DAK]

I am installing a new FF in my yak. Up until now I used a handheld and just rested the transducer in the bottom in a puddle of water. However with my new one I am putting both the transducer and the battery in blocks of closed cell foam that I want to glue to the bottom of the yak. Question is, what would be the best adhesive to bond foam to ABS plastic? Thanks for any info.

I dont know of any kayaks made from abs. But we use GOOP eclusivly here at the shop to glue the transducers in to Polyethelene yaks. I did over a dozen yaks in the last three weeks. Make sure the foam is cut right so it doesnt squeeze the transducer back up after you place it in the goop. I use sill plate insulation. Its only about 1/4 inch thick.

DAK,  I agree with Barrel... "GOOP" is what I've used in the past. Last install was in a Tarpon 120, GOOP'ed transducer right to hull, no foam block, no problems for 5 years!
I intend to do the same with the Phoenix, just rcv'd the FF last nite - Cuda 300...

Thanks guys. I don't want to permanently glue my transducer in, so I'm going to try just glueing the foam block to the hull, put a little water in the cutout, and stick the transducer in. This should work right?

I thought all plastic yaks were rotomolded ABS...they're polyehtylene? Learn something every day...

Vaseline is a better choice then water inside the foam moat.

I have heard that one as well, although since vaseline is a petroleum product it is less dense than water, which makes me think it would weaken the sound wave going through. I will give it a try though...
