    '08 15HP Yamaha pulls right

    Last summer we got a new outboard (2 stroke) and oddly it pulls to right hard. What I mean by that is that if you were let go of the handle, the boat would steer to the right, sharply. The outboard is centered with the boat as it should and I've never had that experience with any other outboard...

    Flywheel torque for '86 Evinrude 15HP?

    Hi, Due to broken wires where they flex, I've replaced the "stator" (like a PU coil) and and the coil under the flywheel. The guy at the place I bought the parts from (local) had the alignment ring so they're properly aligned but I forgot to ask for the torque spec on the flywheel nut. Anyone...

    Possible Stator problem with 15HP Evinrude

    Over the last few years this '86 outboard has been problematic. I'm now told that it will sometimes slow down (very intermittant) but eventually recover w/o doing anything. The guy who told me about this said he was talking to someone about that and the other guy said his outboard was also doing...

    '86 15 HP Evinrude, intermittantly slowed once as if fuel related BUT....

    This outboard began acting up a couple years ago and although it now seems fixed for the most part, the last time I was at our cabin a few weeks back it acted up for me once (and only once). What happened was that after using it in shallow water (tilted up in its shallow water position) and...

    Differences between EFI 4 stroke 40-60HP, ECM?

    In another thread here, someone posted this:<br /> "As a sidenote I have the partlist for the 40/50/60 EFI 4Stroke (it's the same partlist for all three) and the only difference is in fact the computer (ECM) and decals.<br />Here is the # for the 60 ECM:<br />89195238T ECM 1 $783.00"<br /><br...

    Replacing 50's Johnson gearcase shifter seals?

    I've got a few '50s Johnson outboards and I'm soon to replace all their lower gearcase seals however it seems as though there's a special tool required to replace the shifter shaft seal (or o-ring).<br /> Is the tool still available somewhere or is there a way to do it w/o the tool?

    Opinions on oil types for '03 4 cycle 40 HP Merc?

    I know, it's not really a Merc but Merc has their own "4 cycle oil" which isn't exactly cheap at the dealer considering that it seems to be just regular 10W30 petroleum oil. <br /> Is there any good reason why I couldn't use any other good automotive 10W30 engine oil?<br /><br /> Synthetics...

    Bad tiller throttle cable, '86 Evinrude 15HP

    Anyone here replace one? Easy job or somewhat of a bummer?<br /> The throttle's been stiff for a while but it now obviously has a bad cable near the tillers pivot point area.

    '74 Merc 200 (20HP) shallow running position?

    I've got a nice used '74 Merc 200 (20 HP) and the owners manual that I bought for it from Grubs claims that there's a shollow running position setting somewhere but the drawing in the manual isn't good and no, I don't see anything that'd allow for that anywhere.<br /> It tilts up in forward...

    Waterwitch parts, info?

    Hi,<br /> I just picked up a Sears Waterwitch that appears to be in good overall condition BUT is missing its spark plug. Anyone here know where I can locate one?<br /> <br /> Anyone know where I can find more info on these anywhere?<br /> Btw, yes I'm a member of AOMCI too but I get more...

    '47 Johnson PO-15, source of gearcase seals?

    Might anyone here know of a source for lower gear case seals for a PO-15? <br /><br /> Another Q, IF I can get mine running, can it run briefly, safely in a test tank being that it has no waterpump or would I risk overheating it? I'd think that I could at least run it for a little while...

    '56 Johnson, siezed "steering column"?

    I just picked up a '56 Johnson Javelin that has a very odd (too me) problem. Its "steering column" (whatever) is siezed, doesn't swivel to turn the outboard as it should. I've never seen that before. Great for making constant left circles only but that's about it.<br /> Anyone have ideas how I...

    Best, safest way to remove Dyna Float emblems off repainted '57 Mk30?

    Whoever painted the outboard painted right over the 4 dyna float emblems and so I'm trying to remove them but not yet having much luck. I've gone around the screw heads and emblems with an exacto knife yet I've only got one screw removed so far. I'm still unable to get that emblem off.<br />It's...

    '59 Merc Mk 75A vs Mk 78A, difference carbs only?

    Bore and stroke for each are the same but the '59 Mk78A has 10 more HP. I assume the only difference is carbs (to add 10 HP to my Mk 75A) but is there more to it than that?

    Tools for '50s Merc lower units still available new?

    I see them for sale on Ebay occasionally BUT before possibly bidding and probably paying too much (to outbid others), does anyone here know of any sources elsewhere where these tools can still be purchased new and reasonably?<br />I have a few old Mercs that need their gear cases re-sealed so I...

    '46 Johnson PO-15, 2 gear case fluid sections?

    I picked up a very nice original PO-15 and I'm trying to determine what's suppose to be in the lower of the two gearcase fluid areas. I have a vintage service manual on old Johnson outboards, it shows the 2 areas but I find no mention of what type lube should be in the very bottom. It looks like...

    '80s Evinrude 15 HP won't start w/o starting fluid

    This motor's developed this new problem this year, won't start cold or hot w/o a shot of starting fluid but once that's done, it runs fine until shut off again (plenty of power, etc). If one doesn't have starting fluid in the boat, one's then rowing home.<br /> I suspect that it needs a carb...

    Proper emblem for green '57 Merc Mark 30?

    I bought a nice Mark 30 that needs a new emblem, cracked.<br /> The ads and photos I've seen show this motor with the black background emblem (lower right) but the one now on mine is the one shown in the upper right of the 4 repro emblems:<br /> http://www.iserv.net/~shapton/emblems.html <br...

    Re-sealing two '57 Merc gear cases, easy or a bummer?

    I discovered that both my Mark 25 and Wizard 12 have leaking gear cases and need re-sealing. I know that Grubs sells the seal kits and have service manual for Mercs too but havent yet tryed. Easy I hope?<br />The Mark 25 doesn't go into reverse so I need an excuse to get into that anyway.

    Starter drive not kicking out, '59 Merc Mark 58A

    I bought a used starter for this outboard as its original was totally dead. The used replacement spins but its drive fails to spin outwords to engage the flywheel. Doesn't matter if I bypass the solenoid or not. The solenoid is good. <br /> It's a negative ground starter but polarity doesn't...
