    2003 Merc 75 hp ELPTO Surging / Losing power

    Thanks. Does not seem to make a difference, bulb holds its shape. I am going through it again to replace all fuel hoses, check for leaks, and replacing clips/clamps. It will only surge/lose power while in gear above half-throttle. It high-idles in neutral with no issues --both on earmuffs and...

    2003 Merc 75 hp ELPTO Surging / Losing power

    Engine: 2003 Mercury 75hp 2-stroke ELPTO Issue: The engine will idle easily but surges after about 30 seconds at anything above half-throttle. The longer it idles, the longer it will run at higher RPMs, but it will always lose power-- to the point where it almost shuts down at WOT. It will...

    Diagnosing 75hp ELPTO starting problem

    Great advice. Thank you for the detailed response. I got it running, with full advanced throttle and a few shots of the FE. Ran for about 30 seconds--and would've kept going--except there was no water exiting the tell-tale. I suppose I could fire it up and check for water exiting the...

    Diagnosing 75hp ELPTO starting problem

    Understood-- and thank you again. I developed such tunnel vision with the fuel and spark systems that I failed to consider the weak battery. I swapped it out with a new, charged, starting battery which works wonders. The engine cranked over a few times and shut down immediately each time...

    Diagnosing 75hp ELPTO starting problem

    Maybe I wasn't clear--my mistake. I was expecting fuel to leave the enricher when engaged (key turned and pushed in). As far I can tell, nothing exits the enricher solenoid when it is activated.

    Diagnosing 75hp ELPTO starting problem

    Thanks for your quick reply! Maybe I'm wrong here, but is the enricher more of a valve--i.e. when pressing the key in, fuel is sent directly into the manifold, bypassing the carburetors? I would think that if I am hearing the "click" when pressed, that the solenoid is working well. When I...

    Diagnosing 75hp ELPTO starting problem

    I've got an early 2000 outboard that has been sitting for about 5 years. Plugs, fluids, and fuel has been changed, carbs were cleaned, and the engine cranks healthily. Fuel is getting to the carbs, but it won't start or fire. The enricher clicks when engaged at the key, but with the line...
