Took out my first twin yesterday and noticed the rpms were about 500 off when both sticks were in the same position. It was choppy so I couldn't go above 4k rpms but for the short time I did it seemed they caught up at around 4k . So not sure if the gauges are off ..??
What's the best way to sync the motors? They are Tyler crockett 502 mpi

I do it by sound. A fast oscillation is not in sync. Get that ocsillation as slow and long lasting as possible. Then, the engines are in sync.

X 2. The only thing that sounds any better is trips. I wouldn't be to concerned until you get a little more seat time and go out on a calmer day. Your tabs / trims position along with over all conditions makes a big diff.

When your sinked you get a nice hummmming in your ears especially with some headers.. Be sure a and check your trim and tab position in ref to your gauges from one side to the other also when it's out of the water. Good luck.

I am guessing that once you get the engines synched if your sticks are not even you can adjust them by manipulating the cable connections at the helm/throttles?

By and install a Snyc gauge you will love it. Like said above when it gauge hits the middle and both engines running the same its a sound you will never forget. Like a smooth running sewing machine

He is as serious as a heart attack. Never used one but have seen them. As stated earlier, it is a sound you will know when they are running in Harmony.

Wow, nice. I did not know they where that cheap.

My tach's are not even close. But once that gauge is in the middle you can hear they are both in sync.

I thought came came standard on performance twins

Yes, they exist. I've used them on yachts back before the days of automatic synchronizers. It's just a meter that points straight up when the two tach signals are the same.
