Ran my Boat all weekend ran fine,but when I was washing It I noticed that a small hose on both the drives with a yellow twist lock coming from the uppers to the lowers was not connected.What is this and did this cause a problem?
Drives were off at end of last season when I had boat serviced

speedo

Thanks speedometer worked but thats probably because its a gaps.Plugged it back in so it doesn't get tangled thanks again
