If you give us the Scott year and horsepower and/or model number, somebody here can help you out. Model number is usually on an ID plate somewhere near or on the transom clamps. Do not assume the motor is the same year as the boat, and do not assume the year the seller told you is correct, regardless of what a registration or title says. I find sellers have the correct year about 50% of the time. If you post the model number here, we can verify the year.
To get started on it, any motor that hasn’t been run for a lot of years should have the lower gearcase oil changed. Clean out the gas tank and lines unless they were cleaned/drained before they were stored. Clean or replace the spark plugs. You will probably need a new water pump impeller, but I recommend you get it running briefly before spending any money on parts so you know it doesn’t have a problem that’s not worth fixing. You were probably told it “ran good last time out many years ago” – that line is the biggest joke of our hobby! I’ve heard that several times and found parts missing or broken where it couldn’t have run at all. While you have the spark plugs out, put the wires back on them and lay them on the engine anywhere there is metal and don’t worry about paint in the way. Pull the starter rope and see if there is spark jumping the spark plug gap – if you see spark, it doesn’t always mean there is enough spark to fire under compression, but it’s an easy test and most of the time it means spark is OK.
Welcome to the hobby!….it’s fun!….but beware…it’s addictive – motors seem to accumulate to fill all available space!
