    CDI Pulse Pack Reliability

    In searching for one of my current problems, I got to thinking about my CDI pulse packs. They have the Merc P/N 827509-XX. The engine was built in '02 and the dash was A8. Then one failed about '06 and the replacement was a -A9. Today I am looking at the Merc parts site and current...

    My turn. Hello Certified Merc engine mechanics, Faztbullet, CharlieB and the rest

    I spent a few minutes looking for access to the archives and I couldn't find them...help would be appreciated there, but not the issue. Last time I was out (Mayish timeframe) after a stellar hour or so (off and on) of my usual blasting around the lake at WOT like I like to do, my trusty '02 3...

    Some people just blow smoke!

    I seldom visit this site but am compelled to do so today. I wanted to grease my trailer hubs and I liked the grease I used previously which of a peculiar color and made specifically for marine trailer bearings...had a nice stickiness about it that you couldn't hardly wash off your hands, much...

    Merc Hot Dog Engine Oil

    Well today it happened. I have been "surmising" that the top of the line Merc oil was synthetic. Apparently WRONG. Today I am at WW and lo and behold I see a quart of Quicksilver "synthetic blend". Pricing on it was $3.77 where Merc's TOL oil to date was/has been $3.45. Well so much for the...

    For all you folks choking on 2 stroke smoke.

    The last couple of days I have been on a nostalgic acquisition caper and stumbled upon something I found interesting. Back in the 1949 era, the documentation I discovered (www.wizardoutboardforum.com) said that the oil ratio for one of the small Wizard engines (Western Auto sold, built my Merc)...

    Comment on Good Year Marathon tires

    I read a fair mount on here concerning the pros and cons of Marathon tires. I just put new tires on a travel trailer with a '93 build date that apparently a pair of OEM ST Marathon tires still on it. In deciding to "retire" I checked the tire for weather cracking and found very little to the...

    Sobriety Test

    Well, I can't seem to find any where else to put a topic such as this but I think it's important to the viewers. From time to time, respondents offer responses that are out of line with their normal character. Old timers can detect this but NEWBIES can't. You have to separate the straw from...

    Water in Gearcase Possible False Alarm

    You know, hardly a day passes and you don't learn something new. We were talking about 3 and 6 jaw reverse clutches on the newer 60 (bigfoot)and 75-125 hp engines today so I had my serv man out and was looking the area over, beins I couldn't sleep and I wanted something to go with my cookies...

    Merc 85 hp year model identification

    Caught myself telling a lie yesterday. I was talking about an 85 hp Merc 4 cyl I had back in the '80's (I THINK) and said I bought it without power trim. Well that was the first lie because I distinctly remember running over a concrete anchor to a marina at considerable speed (making a U-turn...

    '50's model 25-35 hp questions

    Was over in props talking about things and the subject of OMC cubic inch displacement came up concerning the old twins that started out at 25 hp (with the sliding throttle across the front and pressurized fuel tank) up through the twin 35's of roughly the '58-59 era. Many a time, as a...

    Torque, Thrust, and Force

    Read a couple of comments yesterday and I think Q.C. and Walleyehed to name a couple, were involved and it reminded me of a personal curiousity that others might also be interested in. Marine Engine Design 101: Ok, let's say that my job is to design a 50 hp outboard motor. We go through...

    JB, what do you think about this one too?

    What about referencing this one too; like the OMC history I mentioned earlier, for the same reason? Thanks, Mark

    Ratings on trailer tires

    I ran across this subject a couple of years ago but forgot the answer. I bought new 6 ply 14" rim tires for my trailer and they were "trailer only" rated. Why is that? Is that better or worse than P or LT ratings as tire quality goes? Thanks,l Mark

    Goes without saying

    Today is one of those days that calls for indoor amusements. In looking for new things to do I happened onto the "Completed Boat Projects" section herein and became engrossed in the first masterpiece: "14' Welded Aluminum Skiff" by Kevin Morin. Humbling does not begin to describe how the work...

    Early Merc 3 cyl lower unit choice

    Ok you guys in the know, I'm going to stumble through this with several inaccuracies i'm sure. My intent here is to answer the question for me as well as others that may have had the same curiousity not focus on beating me up. Grin Somewhere back in the '70-'80 timeframe, Merc decided to come...

    Lower Unit Plug Gaskets

    Just changed my lower unit oil today. Lotta people harp on things and bein a Texas Redneck, I like to separate fact from fiction. When I bought my last 2 Quarts of Merc Premium lower unit oil (for high performance applications, stern drive or OB), I bought 2 sets (6 each, beins mine uses 3...

    I thought my trolling motor was overkill

    Well I did till yesterday. I hadn't used the boat in quite awhile, wanted to run some fresh gas through it, and I had replaced a CDI unit that had a cold temp problem and wanted to know how it worked. I didn't look at the news media on the weather, but I can usually see when a front is coming...

    Lifting Strakes Function

    Seems to be some confusion as to just what do lifting strakes do? Well, obviously, any time you increase the thickness of something, you increase the strength. In the case of a strake, you deform the glass mat to get the strake and the strength, but you don't have to pay the price of added...

    FYI on Syn Oil use from OEM's

    Reading the owners manuals for a farm tractor Cummins Diesel engine, and a Kohler Air Cooled riding mower engine yesterday. Both recommend using parafin based oil for the first oil change then say use of syn's is ok fine with them. Now why do you suppose that is.................because the...

    The Battle is On

    We've been yakin about what to do about your fuel in your fuel tank over the winter the last few days. So I hear that Sta-Bil has a new Marine preservative. I have been using Sea Foam for about a year now, in every internal combustion engine I own and I own all types out there. You be the...
