Re: Transducer Mounting
I always use epoxy resin mixed with West System's number 404 High Denisity filler. I don't use their resin (I get mine from Raka) but I like their fillers.<br /><br />I just mix up a little bit of epoxy and then add filler. I mix the resin/hardner first and take a Q-Tip and dip it in the mix then use it to go in the holes and wet them out. Then mix the filler in until you have a consistance about the same as peanut butter.<br /><br />Anyway the trick is to get it in the hole and to fill the hole. The medical unit where I work gave me a handfull of syringes a couple of years ago. I just use them, with no needle of course, and pack one full of the mix. Then the nozzle tip of the syringe goes into the hole and I blow the paste mix into the hole from the back. Fill it up and real quick stick a piece of tape over the hole. Do them all.<br /><br />Take the tape off the next day and then using a sanding block and some 220 grit paper smooth them out, then hit it with 600 grit paper, then 1,000 and then hit it with some rugging compound and a minute with the buffer and it will look like new. YOu won't have a perfect color match, but it will be white and it will be dead smooth and waterproof.<br /><br />Its really not much work to do. When I mount a transom mounted transducer I like to just go ahead and laminate a block of plywood and then take that block and epoxy it to the trasom. Then I can simply mount into the block and not penetrate the gel coat. It goes a long ways towards not getting transom rot started. I simply do not trust 5200 or any other sealer to stop water intrusion into a transom. If the block starts to rot off you can easily replace it. Put a little paint on one and it doesn't look bad either. The if you have to move the transducer you really don't care much about the old holes, but if you do they are easy to patch.<br /><br />Thom
