I have a 65' 15' Sears Runabout that I want to fit a 66' 40653B Evinrude 40hp Big Twin mounted with an Outboard jet's Model B Jet pump.
I need to rebuild the harness from stock junction box through to my engine. I don't need help with wiring so relax. I have 4ga red & black for the starter.
I...
I hope you got your engine running again.
Oh! did you check to see if your prop has spun or loose on its rubber hub? That will cause a loss of power too.
I should also say that it is not safe to run your motor at Wide Open Throttle with "Muffs".
and Diesel fuel makes a GREAT carburetor cleaner, No need to "boil" out the residue.

Rebuilt the carburetor, Replaced the fuel pump and the cowl mounts.
I'm trying to synchronize but the images in the Seloc book for a 1961 'type...

This system is THE MAGNETO
These parts usually don't fail.
Points will wear (transfer metal from one contact to the other,) if the condensers are (rarely) bad usually...
If it hasn't been started in a while, try squirting oil into the cylinders.
I know the fuel mix says 24:1, I mix mine at 32:1. It's just too much oil in my mind.
If you have a single line fuel tank you need the vent opened to run. I've never dealt with dual line system but yeah it would need to...
The water comes out of the exhaust port, the one where the rubber boot connects to the rear housing. If it does not start within a minute you have impeller issues. Water in a barrel should be above the vent on the port side of the lower housing. You do NOT need the thermostat. Unless you run...
