The shop I purchased this o/b from was demonstaring the engine in a big tank at the rear of the building to show me the "no start" condition was fixed (new powerpack was required).
They had backed the boat/motor/trailer to the tank and lowered it in with the tilt. It was running pretty good so the tech put it in gear and reved it up to about 3500-4000 and got the tank pretty churned up (the tank is about 4 feet wide, 12 feet long and pretty deep.
Anyway a small rooster tail of water started out the top vent of the tank and at the same time the tell tale stopped pumping water and the overheat alarm started.
The tech reacted by saying...the water gets too turbulent in the tank and eddies near the leg are pulling water away from the intake so he let it fast idle in neutral...the alarm continued for about 15 - 20 seconds and then it pumped HOT water, I mean boiling hot for 20 -30 seconds before the alarm went off and it started pumping cool water again.
I was pizzed off thinking he had roasted the impellor or worse but he insisted there was no harm done. However I noticed that the pee stream appeared to be weaker than before the incident (worn impellor from abuse?)...he said NO.
With some misgivings I took it home but before dragging in 250 km to the lake I ran it on the muffs and noted the left bank (V4) was cool (90 degrees f) while the right bank was hot (137 degrees f)...
I called and told them what I found and was told they had replaced one of the thermostats because it was running hot, they didn't say which one though.
My question is, should I insist they replace the water pump AND both thermostats on their dime or has there been no harm done.
It is going back today (Monday) to deal with the thermostat problem anyway.
