Hi all. So after doing a full service and getting the boat in the water for the first time, the engine runs great. However, when on tickover there doesn't seem to be any water coming from the pee tube! If I give it a few revs it starts coming out. It seems really strong when at full throttle doing 23kts. But when I came alongside my friend, knocked it out of gear and had a chat, the overheat alarm went off and realised there was no tell-tale. Its a brand new impeller so why is it not pumping at tickover anyone?

Did you personally install a new water pump kit? Never do just the impeller; always do a complete kit. A lot of things could cause your issue. Did it cool once you revved it up a little? Check the actual emgine temperature with an IR thermometer to see if you are actually overheating.
 
I bought a service kit off ebay for £115 pounds. What exactly is the water pump kit? I put a new impeller in which was part of the service?
