    2018 MFS20E won't start, No Fire

    Final update!!! The whole cutting out problem ended up being the primer bulb. It was new but broken. I cut it open and one of the check valves was restricting flow. A new primer bulb solved the problem.

    2018 MFS20E won't start, No Fire

    I adjusted the float so that the needle would start filling as soon as the float dropped and took it for a test run. It ran great for a couple hours yesterday. We ran probably 8 miles or so with many periods of WOT as well as multiple startups. Then all of a sudden after 1 startup the problem...

    Could the issue be with the internal float in the VST not allowing it to refill fast enough to supply the engine with enough fuel at WOT?

    I’m back with more problems with this engine. I replaced the high pressure fuel pump and thoroughly cleaned out the VST as well as the fuel filter but I’ve still got some running issues with this outboard. When the motor is on the stand running with muffs it will run perfect. It idles great...

    Circling beck to this thread. I received the new fuel pump and installed it this week. She fired up and purrs like a kitten. Thanks for the help @pvanv What is the typical idle RPM for this engine?

    This weekend I tried the B-12 soaking method. Unfortunately I was unsuccessful in getting any fuel to pass thru the pump. Next I dug into the High pressure fuel pump assembly and found a mess. Thick sticky gunk stuck to everything. This unit needs a new pump and filter along with a THOUROUGH...

    @pvanv Is there a way to test the Low pressure pump to rule it out before jumping to the high pressure pump? The fuel inside the engine smelled awful when I got this motor so I assume it has not been ran in years possibly killing the high pressure pump.

    2018 MFS20E won't start, No Fire

    We'll I went and looked at the engine last night again because I wasn't convinced that the ignition system was at fault for my "no start". When I tested the spark plugs for spark a few nights back my wife was manning the pull cord and I guess she wasn't strong enough to cause them to fire. Last...

    2018 MFS20E won't start, No Fire

    Hi Everybody! 👋👋 I'm new to the forum and outboard engines but I'm fairly mechanically inclined. Recently I purchased a used 2018 Tohatsu MFS20E off Facebook for a great deal to install on my 1540 Jon boat. I assumed there may be an issue with the motor since it was cheap therefore I threw...
