    3 blade or 4 blade means nothing without knowing the pitch of each. any mercury dealer should have them. The correct jet will balance the air/fuel mixture, and aid in running, but you will still experience a loss of power due to the air up there. probably loose 1/2 of your power at 8000. a...

    70hp Force 18’ pontoon

    Just a guess, but start with a 10p or 11p, and then check the rpm with the tach you are going to buy, something like a TinyTach, cheap, portable, easy to use.

    Silicone question

    My guess is that a previous owner did this. Doesn't sound like anything a manufacturer would put any effort into.

    4 flat 7 wire trailer connector

    your whites are all ground wires, they can be connected together. There are a few companies that still make the harness with full length ground wires running to all the lights. But everyone I've seen require you to buy the complete harness, not just the connector with pigtail wires.

    1984 35hp mercury steering part

    You might want to disconnect cable from motor and see just how much the motor can turn. Some older motors just don't turn as far as you might expect them to. You could spend time and money fixing this "problem" only to find you end up with the same result.

    portable jump starter.

    I wouldn't get one of the older style jump packs. The newer Li-ion packs are worth getting. Keep it plugged in so it is always topped off. I've used mine to jump start v8's in -10*F weather. Mine is a NOCO. There are cheaper ones. 1000Amp, 2000Amp, or 3000 amp
