OMG ! We Already Trashed the Dinghy Motor !

[Tori]

Ok so as you may or may not know we are new lives parse and just moved onto the boat
Last night we finally inflated the cute little west marine dinghy so we could take her around to the big boat and have her available to play on....
Having already tested the motor in a large bucket of water all appeared to be well... It is a 2.5 horse Evinrude unknown age. Started great has correct fuel etc. Had to inflate her over by the ramps and them was going to pilot the little craft out into the lake around the corner to the piers on the other side where the boat is. This is a 300 or 400 hundred yard trip. One third of the way motor sputters and dies... Ok she has been stored over a year so no biggie restarts sounds like crap dies again ten minute later and was hotter than hell..... Froze up so we had to paddle the dinghy another 200 yards to the boat lol
Bad impeller? I don't know haven't had time to check had to finish moving out of the house today. Maybe someone has another bright idea?
Good thing we took the oars or one of us would have been swimming ashore
