58 Johnson 10 HP QD 19

[hallal]

I thought some might be interested in my quest to bring an old QD 19 back to life. Maybe even help with the remaining problems...

I picked the motor up last year and gave it a good old tune thanks mostly to guidance from guys on this board.

The motor fired up and seemed to run okay in a trash can. Time to go to the lake right?.... At the lake it ran like a charm....in reverse! No forward gear.

This led me to the shift clutch dog but where does one find one for a motor from the 50s??? Well one turned up over the winter and now I am back in business. Ran it last night in a can and have both forward and reverse now. However, I have two remaining problems. It seems the motor may have a overheating problem which means pull the head and clean it up. Anyone that has any tips for this process feel free to share. Such as where I might find a gasket.

Second I ended up with a nasty skim of oil on top of the water. I know these motors weren't meant to be exactly EPA friendly but it seemed excessive so my guess is a seal kit for the lower unit. What do you all think.

I wouldn't pull the head unless it surely needs it. I don't see any mention of you checking the water pump--have you?

Head gasket is part number 301862. Any Evinrude dealer can get you one. Or, www.sea-way.com

Don't freak out at the oil in the barrel. That's just the way it is.

Did you do the water pump during your mission of bringing it back to life? What makes you think it's overheating? As far as oil, black oil normal, don't worry about it.

I did install a new impellor during the initial tune up but that is it as far as the water pump goes.

Is there a trick to ensure water is indeed pumping? These old motors don't have the pee hole.

I'm basing the potential over heating problem on touch. I ran the motor in the can for 30 mins or so. When I placed my finger on the head above the top spark plug it was no big deal warm but not hot at all. However the same touch test on just above the bottom plug was hot to the point of having to remove my finger in less then a mins time.

I know that is pretty unscientific but add to the assessment that the paint is largly missing from the lower part of the head and I'm guessing the paint cooked off from over heating? Maybe I can post a pic tonight when I get home.

The missing paint may just be a sign of abuse as well though. The motor is a bit of a frankenstein. It appears to be a 58 Johnson engine and cowl attached to a Evinrude exhaust housing with a 58 Johnson lower unit. There are some obvious signes of neglect on the motor but it is a 58 so I didn't think much of it when I got it.

It has mainly been a teaching experience anyway.

If you ran that thing in a barrel for 30 mins and it didn't lock up it ain't overheating. They do however get hotter in some places over others. At the top of the leg there should be a hole for water to spray out of. Over time yes, the paint will come off from the heat. If they are overheating you can't keep your hand on the motor for more than 2 seconds without it cooking your skin.

thanks for the advice

it's good to hear that I may be successful in my restoration. the bottom of the head was defiently hotter then the top but not cook you skin in 2 secs hot.

sounds like I am ready for another lake test. If that goes okay I may even paint the thing up and put some new decals on it.

That's all part of the fun of the hobby! Enjoy
