Again thank you guys, I took pictures of the wiring on my cap and the engine and boat, but having trouble posting them. I know my #1 wire is at 7 o'clock and my #2 is at 5 o'clock. How do you get the #1 cylinder at top dead center and then should I just change the wires and see what happens? Going back to the lake this weekend.

could remove the valve cover and watch the valves. turn engine, intake opens then closes and then bring crank mark to tdc(0*).

or remove #1 plug, put finger over hole and turn engine over by hand feeling for compression, then set to TDC.

best to remove VC which is more foolproof. and yes just can move wires from where rotor points.

You can have the #1 at 7 o'clock right now as long as 843657 follow in that order clockwise until you get to #2. Don't go pulling the distributor just yet unless you have done this type of thing before. Distributor also drives oil pump through a shaft that inserts into the bottom of distributor. Just make sure at this point that rotor points to #1 when timing marks are aligned at crank pulley. If rotor seems to point a little past #1, that's ok. Keep in mind that crank pulley can slip if it has the rubber doughnut in its makeup, so don't completely trust it quite yet. When you get back to the lake take somebody with you that can drive the boat and you reach down while underway and operate the secondaries and see if the engine falls on it's face. If it does, we have some things to check. The engine may bog for a moment while doing this this way but it should eventually start to pull strong fairly quickly. All things considered though, if you were to line up marks right now, put a sharpie mark on distributor body where the number two wire is now and move distributor counter clockwise a couple of teeth so that rotor would point to this #2 mark and move the distributor drive the same amount, and then move wires to the next counterclockwise spot on the cap, you would be set except for setting the dynamic timing again.

So I can't post pictures. So it doesn't matter if my #1 is at 7 O'Clock as long as the order is good from that point?

I went to the lake today and looked over the wires and found out that wires #6 and #8 are crossed. Can I just take the wires off the spark plugs and switch them since they are right next to each other. And my #1 starts at 7 0"clock.

Affirmative. That might just make all of the difference in the world. You wouldn't have to move the distributor either, just leave it as is for now. I'm guessing that the engine doesn't idle very well at this point. Swap those wires though and she should smooth right out.
