Good morning everyone
my name is Dave and this is the first time I have been to your site…
I picked up a small outboard motor at the neighborhood yard sale a few months back. It has a sticker on it that says it’s a registered Antique Motor Club motor
I picked it up with the intention of keeping it at our camp in the Western Maine Mountains (Rangely Lakes Region)
Unfortunatly the ID tag is unreadable so I have no idea what it is. I was hopeful someone can tell me what the make and model is?
it appears as if it only has a forward direction or the user swings it around for direction changes
i look forward to any help and thank you in advance
May 27, 2022 at 11:34 am #260528May 27, 2022 at 11:38 am #260530That is a (modified) Scott Atwater built 3.6 HP with what looks to be a Tecumseh gas tank.
The original Scott Atwater tanks tend to rust out so someone saw that as a workable solution.
Great running motors.

May 27, 2022 at 11:44 am #260531Thank you so much..!
the carb has a needle jet on the forward side… it looks as if it may have had a thumb knob or something but it’s missing…
does that sound correct?
this jet… is it a mixture jet or something different?
any idea what the default number of turns is with regards to closed
Thanks again
May 27, 2022 at 11:46 am #260532That appears to be a Scott-Atwater (or Firestone branded Scott) 3.6 hp motor from late 40’s or early 50’s. The tank and starter are not original. And because the tank is not original, the correct cowling is missing. It does not swing around 180 degrees for reverse, only enough to steer right or left. These are very dependable motors but they have a few things that should be checked. The water pump rotor is susceptible to swelling if it’s contaminated with grease, or hardening with age. Parts are available. Also, if the ignition gives you trouble, the first thing to check is the WICO condenser. I’m not sure whether the lower unit uses grease or oil, perhaps someone will chime in with that info. Also, the factory recommended fuel to oil ratio is 24:1.

May 27, 2022 at 11:52 am #260534The plastic tank resembles ones used on lawn mowers and I have saved a few off dead mowers for just this reason!

May 27, 2022 at 11:54 am #260535Same idea as this one that I test run yesterday for the first time.
It’s a Firestone, made by Scott Atwater.Prepare to be boarded!

May 27, 2022 at 11:55 am #260536thanks so much for the fuel ratio
Unknowingly i would have used 32-1
I’ll inspect the water pump impeller and lower unit
The condenser (fingers crossed) can be rebaselined
May 27, 2022 at 11:57 am #260537That’s a cool video
looks like my unit but mine is a bit Frankenstein
