    Mercury 4hp 2003 fuel pump?

    @pvanv perhaps you can share some knowledge? My motor still bogs at full throttle, despite the new fuelpump..

    Mercury 4hp 2003 fuel pump?

    Is it that gasket that is the culprit? The diaphragm has no visible tear or obvious defect?

    Mercury 4hp 2003 fuel pump?

    Update: The fuel pump looked exactly like the one I have on my 2016 Tohatsu, so I bolted it on, and it runs and starts like a charm. This older motor will need some updates, as I can see it has been tinkered with, missing gaskets and what not. (carb was mounted with a single gasket and the...

    Mercury 4hp 2003 fuel pump?

    Motor won't stay running more than 10 seconds. Mercury four stroke 2003, 4hp, european sold, Serial nr: 0P228224 (Barely readable on sticker and block sticker) Cleaned the carb and checked float and needle. Pull start got on my nerves, so I used my cordless drill. It starts after I have primed...

    4-6hp carb conversion

    I don't get any reply in Tohatsu thread, but I might aswell try here. (This forum has some downsides for us who live in Europe, it gets unresponsive at times) I read through other threads about the carb conversion, and user (technician) "pvanv" recommends the "MFS6A2"-carb over the...

    MFS30C 2015 top end issue

    At full throttle (or even at 2/3- cruising on plane) my motor has a tendency to intermittenly 'drop off' Hard to explain, feels like fuel starvation. It sort of 'alternates' between pushing hard, and dropping off for half a second, then pushing again for like 5 seconds and so on... I have...

    Adding tilt switch on MFS30 Big Tiller

    Yes it has the trim/tilt. And I'll just copy the wires going to the existing button in the 'bottom cowl' of the multitiller. Perhaps I try to make room for that type of button, or Ill make a little 'housing' for it in thin sheet metal. It'll be fine. Thanks.

    Adding tilt switch on MFS30 Big Tiller

    I have 'arthritis' in my right shoulder that really isn't working with reaching over to trim the motor while getting on plane. Could it be possible to add a 3-way-switch, non locking, by jump solder some wires from the existing assy below throttle on the tiller handle? And somehow fit such...

    Decoding sparkplugs MFS30

    I'm back for the 'annual' visit. Pulled the 3 sparkplugs for 3 new as part of 'pre season' oils and lube of the 2015 MFS 30 4-stroke european version Cylinder 3 (lowest of cyl) had a 'gunky' sparkplug, perhaps one can make note of that for future? Reason? The motor runs fine, has no issues...

    MFS 30c wire tach

    Yes. But I'm glad I got a bargain on the motor in the first place. Found this on "faria marine gauges": at red arrows it says that number of pulses is half the number of poles on alternator. So I will set this at "6p" = 6 pulses per revolution. Guess my way through the Grey = sender/pulse, Black...

    MFS 30c wire tach

    Hey gurus. How do I wire the 'cheap universal tach' to the original (european) tohatsu wires coming out of the remote? Color to which color? Is my motor using 6c setting on tach? (Figure I can ask, but also test later on) Thanks in advance.

    Yama F20BMH-2013 aftermarket electric

    So, I've been fortunate to find an almost brand new motor, in europe were I reside. This one was sold without any generator (12v 10A) and now I'm looking for advice on fitting one myself. I have a small motorcycle battery in the boat for my fishfinder (12v 12Ah) and would love to mount it...

    No current to auto-enricher/choke?

    I had troubles starting my df15 from 2007, but it runs great when warm, so I wanted to check autochoke. Did like in some youtubevideos, added 12volt current from a battery, and the choke opened about 4 millimeters in ~5 minutes. It works. Cleaned it and used some wd-40 and mounted it back...
