Finding the right parts for my boat
by Arthur from New York, New York on May 23, 2014
Sirs/Madame The impeller was the right one but I was not sure until I actually installed it in my boat. I always have trouble finding the right parts on your website and often have to buy with less than certainty that I have the right part. My boat is old (1985 Mercruiser GM V8 (I am told it is a 350) and an Alpha I stern drive)and it has had a long block engine replacement before it came to me. The engine and stern drive numbers are not to be found in the boat documentation and I have been unable to find them on the units (stern drive label in gone and no number appears underneath its usual location I might be able to get the engine number if I could stand on my head and had 3 hands). Can you give me a means of assuring that I get the right parts each time or will I have to live with uncertainty each time I buy? Thank you in advance, Jim
