I need some merc savy advice. I have a line on a 1989 90hp Merc that was submerged in saltwater for one nite. The skiff had sunk in the evening and the next morning the mechanic was able to retrieve the boat and motor. The merc was flushed out with fresh water and they changed all the fluids and ran winterizing fuilds, oils through the whole motor. Although it took a little while (because of the perserving fluids) they were able to get the motor runing again and it ran fine. It has now not been run for about 3 weeks. I will be doing a compression test on the engine and will be seeing it running with water muffs. The bottom end was just rebuilt and it supposedly has a new powerhead. The mechanic had just put on a new strator and starter motor. This engine could probably be had for about $900 to $1100 Canadian about $500 American. My question is should I take a gamble if it runs fine or stay away from this altogether and pursue another engine. Another 90hp in this condition but not submerged would run anywhere from $2500 to $3200 Can. Good used 90 to 125hp engines are also hard to find and the dealers can't keep them in stock. As soon as they have them they are gone.
