Went to start the boat to get ready for the season and nothing. That was odd because it was running fine earlier. Checked to 20 amp fuse on the motor it was blown. Replaced it and still nothing. 12.65 volts on battery. Turn key to on position and im getting 12.65 on both sides of relay switch...
Where did the 10-A-1 come from. Thats a good number but missing 2 numbers.
1958, 59
10-A-111....3.6
10-A-112....5
10-A-120....10
10-A-114....16
10-A-121, 122, 123....39.1
you are missing 2 more numbers at the end. Up till 59 they were made by Scott Atwater and last couple years by West Bend. I restored the one in my profile pic and I sent you a private message
Look for a metal tag on the transom. Might have a 217- with some more numbers. Post a picture that helps. The power head tag will have an AV-# that tells what power head was used and what HP. Im gonna send you a private message.
Early ones were made by Mercury I think and McCulloch I think for a year or 2 in late 50's. Whats the model# should start with a W I think. The only year they made a 7.5 was 59 by McCulloch MLM6907A
