    Sync, link timing on a 1986 90 hp (90AETL Euro)

    Y Yes, seem to be like this on most carbed two strokes. But I had an Evinrude 70 some years back where there was maybe 5-6 mm gap and the cam should touch the roller at a specific timing value.

    Sync, link timing on a 1986 90 hp (90AETL Euro)

    Yes, my bad. Moving stator is what i mean (although the term is a bit contradicting). The newer motors has a link to the CDI instead. There may be a difference in idle timing between the two CDI types although the engine block is more or less the same. Anyway, all 90 hp seem to have 22 deg btdc...

    Sync, link timing on a 1986 90 hp (90AETL Euro)

    Thanks, I’ll check. 1. Is the equivalent US model with moving magneto connected to the throttle arm? 2. Any info on the pickup timing or distance between cam and roller on idle?

    Downrigger repair / switch frame - cannon digi troll 2

    I have a digi troll 2 which works great but now has a crack in the frame. Since the frame pn 5530001 is not available I was wondering if I could use another frame, for example the 3392500 which is more common. I don't mind drilling an extra hole or so but I was hoping you could tell me if the...

    Mercury 60 hp 4stroke efi 2004 serial plate position?

    The serial sticker on the bracket on my 2004 mercury 4stroke efi is really faded and completely unreadable. On my previous outboard, a mariner 50 hp 1996 4stroke, there was a round metal plate on the engine block, close to the oil filter which had the serial stamped to it. But on my 60 I cant...

    Is the carburetors interchangeable between a -97 and 2001 fourstroke 50 hp

The 2001 is a 995 cc and shares the engine block with 60 hp of the same year model. Threres only one carb setup on these models and 50 or 60 hp...

    Hi everybody I'm O.D boring my 50 hp 1998 merc since the two mid cyl's are slightly oval/out of round. Questions for all you engine experts: 1. Should I rebore all four cyl's although the top and the bottom seems just fine (when measuring)? 2. Is there any third party manufacturer of pistons...

    Where to buy piston/piston kit four 1997 50 hp mariner (four stroke)

    As title says: Where can I buy these pistons (O.D)? Preferrably as a kit with piston, pin, rings + oil ring and retainers. I've looked at a couple of sites but only found original part and only individual parts not as kit. Doesn't mallory or sierra do pistons for four strokes?

    How does the automatic primer work? Merc 40 hp four stroke -00.

    How does the electro mechanic plunger in the primer affect the fuel system? Does it use vacuum from the manifold plate to draw extra fuel up in the carbs? I'm having trouble getting my merc to run smooth/clean. Also there's a thin gasoline film on the water after a test run. I suspect that the...

    Fuel hose dimensions - carbed 4-stroke 40 hp year 2000

    The hose between the fuel pump and first carburetor is missing on my engine. The "out" connection on the fuel pump seem to be for a 7 mm hose while the connection on the carb is for a 5 mm hose. The shop manual list this hose as one item but does not state any dimension. Should I go for a...

    Mariner 40: No compression - stuck valve?

    I recently bought a Mariner 40 hp fourstroke from year 2000. It's been sitting for about 5 years due to the death of the previous owner. I do not beleive the motor was winterized before this storage. The carbs seemed to be the obvious problem since there's a lot of fuel crystals in bowls and...

    Recirculation on a 3-cyl

    I have a 70 hp evinrude from 1987. Can anyone describe to me how the recirculation of fuel/oil works on the 3-cyl's? It's obviously not the same as on V-engines with hoses and check valves. Recirculation on bottom crank: A small path is drilled/routed through the bottom crank bearing into the...

    Photos of a split powerhead - 1987 70 hp

    I need photos of a split 3-cyl evinrude/johnson from approximatly early 80's to early 90's. I'm having trouble with the top crankase that keeps ventilating through the top main bearing path. My repair manual (Seloc) doesn't cover this at all and I don't have another engine to compare with. So...
