Hi,<br /> I just recently bought a 1985 Evinrude 25hp ob short shaft. i ran it for a day and the next i had problims, it ran for 2 hours and than it started surging, i found out that the fuel vent was closed, but it wouldn't start for 10 mins after it stalled. i got it home and but a new water pump in it. the old one wouldn't pump any water. now that i have the one pump in, the motor still runs about 190* is that to hot for it to run. the tell tale line shoots out waterand the water will burn, but the water coming from the exaust is still cold, whats wrong with my motor, any help will be great!
