Newbie what motor is this?

Ok, I got the gas tank off and found the brass plug. Picture attached. Does this confirm model and year? Or just model?

many thanks

Yup that’s what we need!  499 tells us it’s a 1937 made by Evinrude 4.2hp   You have some work ahead of you!   Is it stuck?  Not an easy fix for a beginner.

good luck!

Is there a website that would help me learn how to remove the fuel tank?

Nick, pretty much all of these vintage motors are simply assembled ( excepting maybe the gear cases). Start by cleaning up the years of accumulated gunk. Once you can see the details, spend some time examining the motor very closely. Look for screws and bolts that hold the pieces and parts together. Soon you will get an understanding how it went together, and conversely , how it comes apart. Take pictures, that will help when it’s time to re-assemble. Also, helps to keep associated parts and fasteners together, in tubs or zip lock baggies. Don’t be intimidated. we all started out asking the same questions.

Thank you. Everything turns on the motor but feels gummy. Both cheeks covering the spark plugs are there but one is broken. The fuel tank has a corrosion hole in it and also pinholes. No decals. I’m guessing parts are hard to find. Appreciate you guys.

Thank you for the encouragement. I’ll follow your advice, especially about taking photos. I know this will be a tough project but since this engine was my neighbor’s and now I know it is a 1937, that means if his dad bought it new, my neighbor was about 3 years old. He said he used it on a wooden boat which I imagine was all the small boats back then. Love to get this working.

Go to ‘Resources’ at the top of this page, then ‘Links’, scroll down to ‘For the Old Outboard’, then click on ‘Art Dekalb…’, then on his site, click on ‘Art’s Extras’, then click ‘Art’s 5 point plan’. As far as the tank specifically, just get a good lead light and look for attachment bolts/nuts. You’ll need to disconnect the fuel line in front of the carb too. In addition to basic wrenches, screwdrivers, I highly suggest getting a handheld impact wrench.

Oh perfect. Thank you so much for the detailed instructions.

Nick….I notice that your pictures are very small…..240 x 320.  It would be better if you could use a bit larger image when posting here.  Usually an image with dimensions 800 X xxxx    up to 1200 X xxxx works best and should still be well within the file size limitations that the site has in place.

Model 449 … the serial number 00450 indicates a very early motor, only the 450th of that model made by Evinrude. Once you get the tank cleaned out and can assess the extent of the corrosion holes, there is a possibility that it can be salvaged by coating the inside with “Red Kote” of maybe even epoxy, I have done that with a “swiss cheese” fuel tank.

Ahh excellent advice. Thank you, thank you. My original pics were too large to post so I went to the smallest. but now with this feedback I will adjust upwards.
