OK. No laughing.
Glue it to the hull bottom in the bilge.
Connect the wires.
Use.
Don't glue it next to your bilge pump. Bilge pumps are typically screwed to a piece of plywood laminated into the bottom of the bilge. Don't use it on a cored-bottom hull. The signal won't cleanly penetrate wood.
Relax, this one's easy.

What about the intake? ANy suggestions there? Also if he is replacing pistons how about stroking the engine?
Another thought will be to replace the prop and have it labbed. It will get you another 2 mph on the top end. If you into water sprots the current prop will be a good spare and give you a lot of low end for skis and tubes etc

coolhand, if the engine has been maintained(oil changes reguarly, the bottom end of your 502 is still solid and you should not have to rebuild the whole thing . Your heads need to be rebuilt with springs, keepers, valves, guides, etc with top of the line stuff. Add roller rockers, then put on Gil exhaust and new risers. You can do this for 4000 to 5000. I did this two years ago and it has been good. The key is to have a good marine shop rebuild the heads with the best parts.

she seems tight i have noticed "chevy smoke" on start up and she uses a little during the summer. the valve guides are probably the start up puff so if the cylinders look good i will just upgrade the heads.

BBC's are known to use a little oil. I have had brand new 396 and 454 Chevelles that used to burn the top 1/2 quart within a day of an oil change. I have also had good 454's and 502 marine engines do the same. Unless you want to be a world beater just do some bolt on mod's with exhaust and maybe consider an ignition upgrade, next lo to propping the boat correctly. I think you would be very happy with it after that.
