Re: old speed boat find
In looking at some of the parts on your motor, I would say that it probably is a 1976 ERude.
As for the fuel pump, the stock setup consists of two OMC vacuum/pulse units, which should probably be mounted on the port side, ahead of the starter. They are the three hose type that receive the impulses via one of the hoses, which attaches to a nipple on the engine. I believe the nipple on your motor is located on the bottom of the intake manifold.
My own choice would be to get rid of the electric pump, and go back to the original setup. The bad news is that the pumps cost about $81.00 each, plus you will have to relace all of the hoses, T fittings, clamps, etc. I think you are also going to have to go through the engine pretty thoroughly, because in looking at the rats nest of wires (coil wires, etc.), who knows what other "make shift" fixes have been made.
You might also want to buy a parachute ..... I think that boat is going to "fly" with a 200 on it!
