"Can't think of a better way to spend Christmas Eve - fixing my 8 HP Honda outboard. Love to work on my boat! So... I took apart the whole lower unit, replaced the impeller (which still looked good), put it all back together, and the same problem remains - no water coming out of the outlet pipe. I'm thinking there is a salt block in the engine, or maybe the thermostat is bad.

"I have 1999 90hp honda,when running wot about 5 minutes red alarm comes on engine shuts down to idle i can get right back on wot in seconds but in about same amount of time it will do same thing.It only does it wot,i can back off throtle will run all day.I changed impeller,thermostat also cleaned on bottom side of where water line goes in a pressure regulated spring thats what it looked to me.was told to take themostat out leave thermostat cover off ran engine in tub of water in neutral at high rpm for a little bit to clean out any build up in ports.after putting back together pea stream still seems to not be as strong as once was and seems to fluctuate.any advice on what could be going on would be great."
