Well first, the oil lines are Tygon, not Tyson lines. I got hit with autocorrect there! I would add a capful of premix to the cylinders before the first start, but you’re going to be running premix for that first tank, so you’ll actually be over-oiling through the break in period. You really don’t need to prime the fuel lines, as they will fill pretty quickly while the engine is running on that initial bit poured in the cylinders, but you will definitely want to bleed the oil pump and be sure the small lines are filling up on the first start. Do a search for bleeding the oil pump, I believe there is a how-to somewhere here.
This is also an excellent time to clean your oil tank and swap to a API-TC rated oil if you’re not already running it. You don’t need to use synthetic in your boat, but definitely make sure it has that TC rating.
