    Mercury 50ELPT BF charging issue 50hp 4-stroke

    I have a Harris Pontoon with a Merc 50hp engine and it has stopped charging the battery. I got it new on the boat about 5 years ago, but it looks like a 2012 engine. Is that odd? Anyway, if I put a fresh battery in, it runs and starts fine until the battery starts getting weak, and then it...

    Coil swap on a Martin 75

    I have an old Martin 75 with crumbling coils. The coils from a similar year Johnson fit over the Martin laminations, but the top wire doesn't quite reach the condenser. The black ground wire reaches. Does the polarity on the coils matter?

    Problem with fouled plugs on '59 Johnson 18hp

    Hi guys, My old reliable 18hp is starting to have issues fouling plugs. I am running JC8 plugs in it. When I clean them up, it runs great for a weekend or two, then starts having issues. It is on a heavy pontoon boat, so probably heavily bogged down at times, but I rarely run it wide open...

    Universal Ignition - Electronic Ignition conversion?

    Hi Guys, I was working on a very old Briggs and Straton lawnmower over the weekend, and was shocked to find that the right solution was to cut the wire that goes under the flywheel to the points and condensor, and replace the coil with a newer one with integrated electronic ignition! They...

    Can I calibrate the trim gauge somehow?

    On my 1990 Chriscraft 20', with an OMC 4.3L HO, the trim gauge on the dash is wrong. All the way down it reads about 1.25, when it should read 0. I have the service manual, and it doesn't say anything in there about it. It may be an adjustment on the gauge, not the outdrive? If so, what is...

    Can I compensate for wrong I/O drive ratio with a different prop?

    Hi Guys, 2 years back, I replaced the lower unit with one from a 5L instead of the 4.3L I have. The final drive ratio is slightly off. I accidentally got to 5500 RPM the other day before I realized the mistake. I believe red-line on the 4.3HO is 4800 RPM. Can I just get a more aggressive prop...

    Pressure Tank Motor Connector Rebuild

    Re: Pressure Tank Motor Connector Rebuild So, after 2 1/2 years of fighting with the Sierra o-rings to connect and un-connect my fuel line from the motor, they finally failed on both tanks. I think the ethenol in the fuel ate them up, as they were crumbling and started to leak. Mostly the...

    Bayliner Jazz sj120- won't turn over

    My friend just bought a Jazz 120, and after 3 weeks on the water, they were running it and it quit while pulling 3 kids on a tube. It wouldn't turn over much, maybe a half a revolution like it had a dead battery. He paddled it to my cottage, and we throw it on the battery charger. 2 hours...

    Older lower unit rebuild thread

    There was a great thread on rebuilding the lower units on J/E 7.5HP - 25HP motors from 1956-1970 ish, and I can't find it anywhere. Does anyone happen to remember where it was or have it bookmarked? I have my '59 18HP all apart and cleaned, and would just like to read thru it before...

    OMC 4.3L I/O - what plugs the hole?

    Hi all, I have a 1990 OMC 4.3L I/O. On the outside of the upper unit, there is a nice Cobra embem on either side. When I pulled the boat out to winterize it, i found the port side emblem is missing, and there is a hole that leaks out all the red pop I am pouring into the PS cooler hose up by...

    1990 OMC 4.3L exhaust manifold - GLM?

    Hi All, Apparently, a couple years back I waited too late in the season to winterize the boat and I had a freeze issue. There is a very minor crack just above the middle spark plug on the Port side. It really doesn't 'leak', it is more of a 'weep' as I can see a fine line of rust forming...

    Champion 5HP

    Hi All, My dad recently aquired a mid 50's Champion 5Hp. We mounted it on a boat, and fired it up. It had been gone thru by a collector who had cleaned it up good, rebuilt the carb and checked the lower unit. I was a little surprised that it started right up. I did notice a problem with the...

    59 Johnson 18HP shift adjustment

    Hi Folks, I have an odd problem that I can't figure out. I was having issues with my 18hp slipping out of gear in forward. I thought it might be due to the connection on the shift shaft behind the oval plate in the leg, but that was fine. Then I noticed that I can adjust the shifter at the...

    Pressure tank fuel line size

    Hi all, This weekend I want to replace the fuel lines from the pressure tank to the connector, and then under the cowl from the engine side connector to the carb. I need to know what diameter hose it is. Is it all 5/32? I plan to use regular automotive store stuff and zip tie it together...

    Clinton Eska 3HP - Is there a fuel filter?

    OK, I was on here a week or so ago mentioning how reliable my little Clinton 3HP has been, and of course, this past weekend it started stalling on me. I didn't have much time to mess with it, but a buddy of mine that got to the cottage before me said that it had run out of gas and when he...
