If you mean the 1936 Johnson Model 100, 1.7 hp, go to www.marineengine.com and look under Johnson manuals. They have a parts manual and diagram for that model for $27.50.
The 1974 is a two stroke and weighs approximately 72 lbs. The four stroke equivalent from Johnson today is a little over 100 lbs.

I just got a boat with one one it and from what ive been able to see on the net, its a 1966... but Im not 100% sure
it all depends on water conditions and the boat.the right size boat for a 100 hp should do around 55-60mph
The smallest motor for a 16 foot Lowe boat is about 30 horsepower. The maximum size should be no more than 100 horsepower.
It can be several things. Here are a few simple (cheap) things to check 1. Does the boat have a sub floor that has filled with water? 2. Is the motor trimmed in? 3. Are you using the correct pitch propeller? Once planed does the engine rev to manufacturer's specification? 4. Is the bottom of the boat "bowed" or have a "rocker" as opposed to concaved which would make the boat plow.
although the sticker on it says 100:1, mix a 50:1 ratio. In 1986 & 1987, for some reason Johnson went to a 100:1 recommendation. I actually like a 64:1 ratio in my pre mix 2 stroke outboards. That's 2oz of oil per gallon of gas.
$50 - $100. Depending on parts required.
Generally, somewhere in the 100 psi range, with a minimum of around 80 - 90 psi.
