@Mr. Anderson OK, Mr. Anderson I have a rubber piece at the top of my water flowing and I have another piece up inside so them to join together, would you put any grease on the rubber the slide in there?
When I take this over 10 mph the red light will come on until I drop the speed back to about 10mph. The RPM does not drop until I do it on my own. I don’t leave it above 10 mph long. This is on a small 16 foot StarCraft so weight shouldn’t be an issue
