    Checking plug color for heat range?

    As a brief background, I have a 1987 Evinrude 48 ESLCUS (originally) -- the (clod!) rebuilder I got it from put on different carbs (top) # 318505-D2 and (bottom) #318505-D4 and they have fully adjustable needles. The water pump was bad as purchased, overheated, so I got to have the head shaved...

    Fuel supply fix - by accident

    Maybe here is a fix for some fuel delivery problems. My '87 EVrude 48 got a complete fuel system re-do last fall. Ran super the last couple runs on the lake. What I did was plumb from the tank to a screw off water filter, then to a Mr. gasket #42S electric fuel pump (at the suggested 45deg...

    Alternates to OMC motor sealants - If Any??

    In replacing the head gasket on my Evinrude 48 ESLCUS - 1987, twin cyl. I see that my book calls for Gel Seal 2, Gel Seal Gasket Remover, and Cleaning Solvent -- all by OMC of course. My local marine place is reeeal expensive on this stuff, 20 miles out, and sells it in way larger quanities...

    Evrude 48 - one plug cleaner than the other ??

    The lower plug looks like new, clean etc. The upper plug looks normal brown ceramic, and black electrode as shown in repair book. I'm thinking a blown or leaking head gasket, not too bad a project, but motor runs good now, had it on a local lake for a couple hours!! We are getting ready for...

    Evinrude Carb. Model Number check, Please ??

    Ok, on the Evinrude 48 eslcus twin -- vintage of 1987 -- that I bought recently, I found that the carbs do not match any numbers or pictures in the repair book. It is a bit of a chore to get it tuned right without knowing what they came off of. I just rebuilt the carbs and got it running, but...

    1963 Evin. 3 hp. twin - Best Oil mixture ?

    I just bought a 1963 twin cyl. Evinrude -- IBoats says this is a 24/1 oil / fuel mix. The motor verifies that on a sticker, so this one must have the older bronze bearings in it. Good compression, a superb motor of its type. Question is -- Is there a better type of oil for this motor, and can...

    New Decals E'rude 48 spl. -- Where ??

    Got the cowl painted, but new decals seem to be nowhere around. Somebody must make replacements. I would like the full set if possible, but after two hours on thw web no luck at all. I doubt the factory would even touch 1989 vintage decals, hope I'm just looking under the wrong heading ...

    Best '87 Ev-rude spark plugs 48 spl ??

    I finally got the rebuilt 1987 motor on the boat. It is the 48hp spl., no oil injection but the builder did rebuild a pair of carbs that have adjustable main and idle? jets. The originals were not good, so replaced with rebuilt units, not sure of the year. Starts with a key flick, runs really...

    Thanks for merc Info.

    With what I learned here, I managed to find that the top two cyl. on my EX-115 6cyl. Merc. were set by the dealer just enough lean that they slowly overheated at top throttle. I replaced the fuel pump twice, the coil once, and wondered what the problem was. Water pump tested out good, all to...

    Evinrude Steering Part needed

    The "new to me", Evinrude has just one part missing before I can take delivery. My dealer is looking for a 1979 --- Evinrude 25hp. --- steering swivel. The motor is a long shaft, if that is important, but he didn't give me a serial or part number. probably surprised him by hunting for this...

    Thank You for the help !!! Merc 115 OB

    Just a big thanks to all, for the advice and info. on what to do with my blown Merc. I traded it off for an "Evinglide" or "Powerrude" 25 long shaft, with remote controls. Not as fast, but adequate for fishing our local lakes with a 10 mph speed limit, and quadrupling my gas range. This...

    Merc 115 - Going Away

    Thanks to all who answered my previous thread !! The decision has been made to get rid of my '77 Merc 115. As it is much more expensive to rebuild than I can afford now, I am going to let this go away, and get on with boating. Sometimes retirement is a drag. Anybody wanting a Merc 115 for...

    Merc 115 - Blown Out & Further Revelations

    Spent yesterday with a mechanically adept club member, and got grilled on my motor problems. Yep !!! It was all my fault, gotta admit it at last. Less than 50 hours and I did myself in. Here's how it got burnt out so soon. Got the rebuilt (very tight) motor in the fall, cold water ok. Did...

    Merc 115 Powerhead Question

    Earlier today I posted that mt 115 was Blown Out, from overheating. In talking to another club member, he says that if I have low compression, but it starts -- there may be an option to try before I scrap or trade the motor. I'm curious if anybody else has heard of this?? If overheated, but...

    Merc 115 - Blown Out

    A year or two ago I bought a freshly rebuilt 1977 two stroke 6 cyl. Merc 115. A dealer, and friend of mine did his best to give me a great running motor. Unfortunately, I ran it through polluted water or something evil, and ruined the water pump, at less than a hundred hours of use. It got...

    1977 Thunderbolt 6 -- Ignition Miss ??

    The last outing the motor stopped in mid lake, just sputtered out from a 4000rpm cruise speed. Waited a few minutes while on electric troller motor, tried to start it, and starts right up, no problem. Ran strong all the rest of the day, but I'd like to be sure, as I will be on the Columbia...
