Hello All,
this is my first post so I hope I can make sense with my problem description.
My 1980 75 HP Evinrude totally bogs out on acceleration - unless I run the fuel line directly to the fuel pump (without the primer bulb or water separator).
this has been going on for a while and it's been in the shop several times for the same symptom. It runs fine for one or 2 times out afterwards, then goes back to the bog and only goes 5 mph max. It seems like the shop doesn't really do anything - it just runs ok for a while is my guess but I'm totally frustrated and out almost $1,000 to them so far.
I always use fresh fuel and add Starbrite treatment in a 6 gallon portable tank and I added a gas/water separator too.
After this last trip, I thought I had it figured out. I was out and it started bogging bad again. I bypassed the primer bulb and gas/water separator and it ran fine. WOT was great and idle seemed even smoother.
I bought a new primer bulb and new filter for the separator. It ran ok for a few minutes, then same thing. I bypassed them again and it ran ok. The clamp fittings and hose are new.
I'm thinking fuel pump?
any suggestions would be appreciated.
