hello everyone. I know very little about outboards, so bear with me. To make a long story short, I acquired a 59' 10hp evinrude for $75. i was told it was a late 70's motor. When I saw the fuel connection, I knew right away that it was alot older (I had a 57' evinrude). I figured for $75, I could figure something out. I have read on how to convert to a Mikuni fuel pump, but I kinda get lost (not knowing anything about outboards) and I don't want to "modify" any of the original parts. Here is the question. Can I run an electric fuel pump? I have no problem using a pressure tank (once i find one), but just wanted something a little easier (and less costly).
Here another option. If the motor had the option of a fuel pump, could I just install a correct fuel pump? I would have no idea what part number or where to find such a part, but i can figure it out.
The '59 already has a regular fuel pump.
Does the engine have a white cowl,or is it red(holiday bronze) and white?
Maybe you have a a '57 body under a '59 cowl?
Anyway,those old 10 horse engines will run another fifty years.
I believe you can get the fuel pump off a '60 or later and the bypass cover (The important part) and it will screw right on. Then you will have to re route the hose and change the connectors.
You could use a mikuna or an electric but I would either use a pressure tank (they do work!) or upgrade with the parts from a newer engine ('60-'63)
Before you go any farther though check the compression to make sure it's worth putting loot into.
its got good compression. dont know the exact numbers, but you can feel it when try to start it. thanks for the info. i dont have a problem using a pressure tank, just wanted to know what other options i have. thanks for the help
I think Samo is right about being able to do a conversion. If you do, don't forget to remove the nipple on the front of the leaf valve cover, where the pressure line was attached. You can then plug it with a stainless screw of the correct size and thread count. If you don't do this, your motor will "spew" premix into the cowl on each pressure pulse. Be sure that the screw you use is not too long, because it will most likely hit the leaf valve assembly behind the cover, if it is!
