Hey all,
I have a 2018 (maybe 19) Honda 9.9 powerthrust that is giving me problems. It starts up with no issue but water does not come out of the “tell” unless I rev it a bit. Is it idling too low to engage the impeller? Is there a way to adjust the idle? It stalls out sometimes too if just idling.
A little history on the water pump. Last spring when I went to fire it up for the season (northern Michigan), no water came out of the tell so I brought it to a shop. The guy said the impeller was total destroyed and he was a little worried that some of the pieces might have gotten into the cooling system. I ran it all season without issue although I always felt it didn’t have a very strong water stream at idle and it would occasionally stall out. I mostly use the motor for trolling so it almost always has a “load” on it and performs just fine.
Another detail is that when I checked the gear oil before winter it had a little water in it. It was a very small amount of milky color but I drained it all out so it wouldn’t freeze. Is seems strange to me that this new of a motor would already be having these kinds of issues. Could water get into the lower end from the impeller housing area?
A little more detail to add. sometimes when I start it, the water comes out within a few seconds, but then once it gets to its idle speed, the water stops. Before its stops and its just a trickle, the water is SUPER hot. If I rev it a little, the water will come out faster and cool off. I wonder if it is stalling at slow idle because it doesn’t want to overheat?
Any help on this is appreciated.
Thanks
