Re: help with montgomarywards 7hp
Hi,
Your outboard was made 1973, by Clinton, for MW. The actual model number on the outboard would start with KTV. If you can find that, I can tell you the exact year for sure, but 1973 was the only year the K700 Clinton engine was used in a MW outboard.
Fuel

il ratio for other Clinton-based engines in that age range was 24:1, and that should be safe for yours, although I do not have the specifics for your model. Use chainsaw oil or TCW3 outboard oil. Either one will work.
It has no reverse.
Will it push a 14' boat? Sure. Will it plane a 14' boat? Probably not. Those single-cylinder air-cooled outboards from that era generally don't do as well as similar sizes of 2-cylinder water-cooled outboards.
