The pump doesn't suck much at all, and putting it in a tote even that high is not enough. On the hard it should always be with muffs
Since muffs do not work its either the muffs (cheap ones, something wrong with them) or there is a restriction between the drive and the pump
The VHF gets out much farther then CB and its clear. Last time I checked (few years ago) it was still illegal to put one in a vehicle, but as many things, its only if you get caught.
You should have 240 to 33 ohms (cold to hot) gauge and sender.
Take the wire off the sender at the thermostat. With key ON (motor OFF) ground the sender lead to the block. Doing this should peg the gauge hot
Lots of rust, must be near or on salt water
Agree, think I would replace the coil also
The post does rust up if unprotected. Put a thin coat of grease on it after taking a small wire brush to it
