Recurve, can you find the exact spot again? If so, get the biggest magnet you can, and tie a line to it, and lower it down to the RR Spike Hawk, and pull it up. You can go on line, and look up rare earth magnest. There are various sites on there. I went with K & J Magnetics, Inc. there is no minimum order. I ordered, some in varying sizes, and a couple in 1 inch, by 1 inch. They tell you not to get near electronic items, with the one inch ones, as it will mess them up. Especially cell phones, computers, pace makers,etc. However, these magnets, are extremely STRONG !!! They would have no problem, pulling your motor up! I had one in my pocket, and was cooking, and I had all the burners, covered with pots, and pans, and I had just taken a now empty hot pan off the burner, and put another on, and went to turn to put the hot pan in the sink, when I was pulled to the stove, and there I was !
I couldn't get it off, and I am holding this hot pan, trying to figure where to put it, when I was able to slide the magnet in my pants pocket down to the opposite edge of the stove, and twist and pull at the same time and was able to get free of the stove, and quickly put the pan in the sink, and made a note not to put the magnet in my pocket uncovered, and not in a non metallic covering. They come with plastic, and plastic foam pads between them.
I had to take the one inch ones, and put one in a vice, and then very quickly yank the top one off. Then put it in something non metallic, or in an aluminum container, and then I had to roll the one in the vice up, and grab it, and yank it off also. Oh, I tried to put the separator pad between them, and pinched the snot out of my finger, got torn skin, and a nasty blood blister. They are indeed powerful. And they have bigger ones! But you can get one or two of those, and put them in a small can, and put a hole in the upper rim, and put a line through that, or put them in strong nylon type of bag, and tie a line to that, and then drag it across the bottom, and you should get your RR Spike Hawk back. Who knows, you might get another boat motor......or some disposed of evidence.....
But these things are powerful. You can just google them, and get a display of the products, and email address.
Well, you might want to be careful when she has that little rifle. She just might find it makes a handy little club! ;
I would not want to hear about you getting severely beaten about the head and shoulders with a.....Cricket ......
