Posted last week about an engine shut-down problem after it runs perfectly for 20 minutes or so. HAve to sit and wait 1 hour or so to get it to re-start. Engine turns, but will not run. Suspect it is a heat-induced intermittent failure of the powerpack.
Took it out yesterday, went about 1 mile and engine started and ran fine. Sat for about 3-4 hours fishing, but when I went to leave I was unable to go beyond idle speed. Seemed like only 2 -3 cylinders firing.
When I fired it up on muffs last week, I noticed that water leaked around the seam between the lower unit and upper. I have never seen an O/B do this; I always put sealant there when replacing the impeller. The jet from the telltale on muffs was a trickle.
My hypothesis is that I have a weak water pump which isn't pumping enough cooling water to the top of the engine, which is where the powerpack is.
Can the powerpack actually be good, and just shutting down when it gets too hot up there ? Incidentally, the surface water in the JAmes River in Richmond yesterday was 100 degrees. I didn't beleive it until I got in the water; it was like a hot tub down to about 3 feet or so.
