    • 6bt 5.9 180 HP running high on temp gauge

We drove it like this for 4 days and we always checked both en…

      March 31, 2020 at 12:39 pm “Crazy behavior” in many instances points to bad electrical connections especially grounds. Have you checked, cleaned, lubed and re-seated all? Since you have twins, have you tried swapping the gauges?

      October 13, 2019 at 1:11 pm If you are getting full travel on the throttle, and are not able to achieve same rpm both in forward gear and in neutral, your vessel is most likely overpropped. (Assuming bottom and running gear are clean) This may be intentional, especially on a big, heavy vessel with limited power. If the previous owner kept records, you might be able to look up prop specs to verify.
