Help! After 40 years with a sailboat, I finally saw the light and brought a 2002 Maxum 3100 SCR. Now I wonder if I made a big mistake. Took the boat out yesterday and when we came back to the marina, the port engine didn’t want to shift to nuetral. Are stiff controls typical of 5.7 Bravo 3’s? Also, can’t seem to maintain speed between 28 and 10. What am I doing wrong?
