Wow, that is a flat cam..... I prefer to see more duration on the exhaust side than the intake. Seems to me that cam will bottleneck the engine.
One question that was never asked of you in this thread and should have been the first..... How old are the manifolds and risers? Just by...
You are right. fastener manufacturers do have charts for using lubricants or dry applications. Most fasteners should have some form of lubricant...

two things,,,,,, your automatic choke might be set too tight or your float level is too high.
General rule.... the top of the exaust riser inside the boat should be at least 12' - 18" above the water line, if it is, you are fine with your...
the parts books do not show any modules earlier than 1986
That engine sitting for 15 years..... will likely be a money pit and way too big for the boat. Sell it, get a 30 - 40 HP engine and have fun.
I am a marine mechanic here in Fla. Typically, a four stroke outboard will cost you more in maintenace than a two stroke couter part, but not much...
What altitude are you at? Try two things. First try pumping the primer ball at full throttle and see if the engine spools up. If it does, then...
