Re: Evinrude 70hp cutting out/bogging down on throttle

Have same issue with 1995 Evinrude 50hp E50TLEOD. Boat had been left for 4 years in slough. Found, good compression, towed home. Mechanic cleaned carbs and engine fired up. Took out for about 3 hours combined run time. It would idle and when went to put in gear had to rev and quickly put in gear.
Took her out again and seemed to bog down. Changed fuel lines, filter. Not sure about carb adjusting screws. They are turned out about 5 and a half turns. She Will idle but rough. She dies when placed in gear. Not sure what else to do. I use non ethanol fuel, Startron and put SeaFoam in tank. Fuel mixture is 50:1. Any ideas appreciated. Someone did suggest I check all grounds. Havent done that yet as I felt this was a fuel delivery issue.

What are the compression readings for all 3 cylinders?

Does the spark jump a 7/16" gap when cranking over ?

 

What is the model number of the engine?

Would stretched cables make this happen? Maybe a dumb question.
