I have a 1994 Mariner Magnum 40HP tiller.
I put a new impeller in it in early 2017, old one was gone.
When I am running at idle or slower speeds, I get a good healthy stream of water.....about 97% of the time.
Sometimes the stream will stop for a few seconds, then start right back up again. It's hard to tell if I am getting a good stream of water at full speed, since there is so much splashing around that area, I can't tell.
Is this normal for the stream out the peephole to stop once in a while, then start back up again ?
I make sure that the tube from the top of the engine is clear and it seems to be, I've cleaned it out a number of times.
The water coming out is very, very HOT, which I assumed it would be.
Otherwise, it runs out good.
Could the impeller be going bad that quick ?
