hey!
Just got a 15ft trihaul with a Evinrude 1975 70HP (70573B) motor on it and i have a few question.
they guy i got it from replaced the lower unit last year. Now i dont know a whole lot about boats (this is the first one ive ever owned, nore has anyone in my life ever owned one ) however, i can read. and im fairly confident that there should be water venting from the two holes at the back of the motor. now one would believe if someone replaced the lower unit, they would replace the impeller. however, when the motor runns its bone dry back there, just fumes.
is this normal?
or does the boat need to be in gear?
my common sence tells me the impeller is fried and needs replacing. submerged the unit fully and nothing. also ran the motor while checking to insure it didnt overheat.
now that being said. after running the motor in a drum, i get some serious black oil in the water. tank is mixed at 50-1. motor runns like a dream stars right up. if the lower unit was replaced and never ran, could it be grease or something?
thanks guys
