Just replaced the water pump in my 2001 9.9 seahorse. Running it on muffs, how warm should the powerhead get to the touch? It has great water flow out of the peehole, but I cant for the life of me remember how warm it got before I replaced the pump. I can touch the powerhead, but It gets real uncomfortable after say 10 seconds to keep my hand on the powerhead.. I just want to make sure of this before I take it to the creeks this weekend.. Any input appreciated..
