    Socket for cowhorn bolts 10-58640

    Hi. I have a very small leak and water coming in right around the cow horn. I am trying to see if the bolts (#10-58640) are tight on the cow horn on my Merruiser 3.0. What socket fits on these bolts? I can't seem to get anything to fit. Does it require a special tool from Mercury? If so...

    1974 evinrude 15 hp drops our of forward gear

    Before putting my small pontoon boat away this fall, I noticed while I was driving it full out, it suddenly dropped out of forward gear and which sent the engine reving wildly. I quickly lowered the throttle cable and figured maybe the throttle cable had loosened somewhat. I checked and...

    Mercury 15 lower unit where to find one?

    I've been looking off and on since early spring for a lower unit on a 1993 Mercury 2 stroke 15hp short shaft. It seems extemely rare in my area. Where could I find one used?

    1974 Evinrude 15 stalls after 2-3 minutes of trolling

    This engine starts fine, runs well at all speeds, but will not troll at idle for more than a few minutes, then coughs a bit and dies. It starts up right away and repeats 2-3 minutes in and then dies. If I give a bit of gas just before it dies, it'll go again for 2-3 minutes then wants to die...

    Evinrude 9.5 needs constant fuel bulb priming

    If I run this motor at WOT it will start to slowly cut out if I do not prime the fuel bulb continuously. I have taken off and dismantled the fuel pump, but cannot see any tears in any of the diaphrams anywhere. It has me wondering if there would be any other reason it needs a primed and very...

    Merc 15 two stroke foot/lower unit

    If anybody has a Merc 15 lower unit to spare or an inexpensive motor with functioning lower unit, let me know. I believe the 6,8,9,15 two strokes all have the same lower unit. Mine is a 2003.

    Evinrude 9.5 spun hub or...

    Hi! My Evinrude 9.5 (1966 year) seems like it may have a spun prop hub but I'm not sure. As I accelerate to about 1/3 throttle all is fine. If I try to go faster, the engine starts to rev quite high but I get no push forward. If I throttle down, it grabs again and pushes the boat forward...

    outboard electronic ignition conversion kit

    Years ago they use to sell a small red electronic item about the size of a coin that replaced points and condensors. I had put one in on an old Westbend 3.5 hp motor and it's still going strong to this day. Do they still sell this anywhere? (I know Pertronix makes it for inboards as I have...

    Evinrude 9.5 flywheel removal

    I want to check the points & condensor on my 9.5. The nut seems to be on quite tight on the flywheel. What's the trick to keep the flywheel from turning when trying to remove the nut? Also, how many lbs do I have to retighten it once I put it back on?

    Hi! I just picked up an old Evinrude 9.5 model 9622A serial #499541. It's really in nice condition considering it's age. Can someone tell me what year and what spark plugs and gap they recommend?

    Mercury 15hp skips a beat

    Just purchased a used 15 Mercury 1993 2 stroke (with 12 volt charging feature) and had a chance to put in the water but only on shore (the lake is still frozen over!). I noticed at slower speeds, especially idle, it sounds like it skips a bit and then dies. At higher speeds the skip is barely...

    Adding power trim fluid to an OMC Cobra

    What fluid is commonly used in OMC Cobra power trims? Do I need to stick to the OMC brand or can I use something else? Mine is a little low because when I trim all the way up, I loose hydraulic suction(the motor goes fine). If I don't go all the way up, it works fine. I don't think any fluid...

    red stripe Mercs

    What years were the red stripe Mercs made? My neighbor has a 60 hp on a 14 ft ski type boat. What is the difference between the blue striped Mercs and these red ones(other than the red stripe being an older model)?

    Average slip ratio

    Knowing that there are many different hull designs out there and looking specifically at bowriders. What would the normal or average slip ratio be of a 16-17 ft bowrider? I ask this because I am starting to think that my foam is water logged and making the boat heavier and slower than it...

    growling sound from drive area

    I've been noticing a growling sound from my OMC cobra drive when I have the drive tilted higher up to get to my now shallower dock (the water level has been going down in the lake). The sound disappears when I can get to deeper water and tilt the drive down to "normal" operating angles. It is...

    To remove the glaze in the cylinders or not?

    I just pulled my head off my 3.0 a while ago due to a blown head gasket. I had the head resurfaced, as well as the exhaust ports on the head and the manifold. Upon inspection of my cylinder walls, I can see small areas of very,slight glazing about mid way in the cylinders. Q:Is it a stupid...

    head gasket installation

    I went boating the other day and all was fine until I wanted to start up again and go and....what the heck!!! A loud popping sound from the carb. It sounded like I was riding a Harley on the water! I had little power and just limped back to shore. After much testing and checking, I could only...

    Getting up on a wakeboard

    For our daughter's 17th bday we bought her a wakeboard. Tried as she could, she just couldn't get up on one. We have a 16 ft 3.0 inboard 17" pitch prop with a tow eye at the back (no tower). She gets up real easy on water skis and a knee board(she snow boards in the winter), but has tried and...
