    58 18 hp Needle Valve Loose

    I got the motor all fixed up about 4 years ago but never got it “wet” (life gets in the way of fun). Finally got it one the boat and it started after about 8 pulls - not bad. Got it out on the lake and got it up to WOT by dialing in the high speed mix. Trouble is it the desired pointer setting...

    Repair How-Tos' on YouTube

    There was a series of videos on YouTube showing various repair and overhaul jobs on vintage OMC's. I can't remember the poster's moniker but it may have been"xxxxx Garage" or something (real specific ain't I?) - but my memory isn't that good at the best of times. The videos sounded like they...

    Johnson 1958 5.5 hp Restoration Question 2 - Throttle Roller?

    All the restoration websites, part listings etc etc show the timing advance plate rolling back and forth on a roller. Mine (special that it is....) has no roller only a spring-loaded bare metal arm that controls the carb. It must have been run that way as there is white grease to facilitate the...

    Johnson 1958 5.5 hp Restoration

    Re: Johnson 1958 5.5 hp Restoration Thanks guys! Still not exactly sure where it goes - in the links KFA provided my old eyes can't seem to see it on the completed magneto plate. I will go down and stare at the engine some more. I guess I just use a very, very small drop of the oil from the...

    Johnson 1958 5.5 hp Restoration

    I picked up a 5.5 hp as my first top to bottom restoration that I am doing all on my own. I finally got the flywheel off (man that was a bear!!) changed the coils but I have a question about the points. In the tune up package I bought and in the OMC parts listing they show a small "felt" oiler...

    Re-Rigging: Merc to OMC - Big Job?

    Offshot question to my earlier thread: I realize there is alot of "depends upon" in any answer without seeing the job in front of them but any idea is good info............ Is re-rigging from a Merc 60 to an OMC 90 a large job? What would a really rough hour estimate be to re-rig if I switch?

    In General Only - Good vs Not as Good Years of OMC?

    I am starting a search for a 90 hp 2 stroke - used. I am targeting a Merc first only because that is what is rigged on my boat now and the re-rig will be easier if I stick with that make. However in order to expand the pool of available engines I have not eliminated OMC's if I can get a...

    4 Stroke Trolling = Engine Failure??!!?

    I heard from someone who indicated their Mercury 4 stroke (60 or 90 hp I think and out of warrantee period) had suffered major power head failure (broken connector rod). Their tech told them that "Mercury advises against long-periods of low speed operation (trolling) as the unburned gas builds...

    1st Project '58 Johnson 10 hp

    Hi - I yes picked up a very cheap QD-18 as my first restore project. I basically got it for $25 in non-running condition, so I don't have alot into this thing if it is a basket case. I could part it out and with just the tank I'd recover my investment". I have a shop manual and have seen...

    WOT - Throttle Cable Adjustment - Bring Up RPM's

    I was out with my "new to me" 1992 60 hp Mercury - it powers a 16 1/2 foot single console aluminum. At WOT and properly trimmed the best I could do was 4400 rpm (28 mph). Based on Mercury's spec's it should be in the 5000-5500 range. The motor seems to be running well - it starts well and...

    I need tires on the trailer I pull my 14' tinner around on. Maximum weight might be 600lbs or so. The rims are no great shakes so I thought I would replace them as well. The exisitng set are BR 78-13's, 4 lug. I can get pretty crappy/generic bias ply trailer tires w/ rims in a 478 -12 (an...
