    '72 50hp johnson, update, question

    Well, I finally had to just give up for a while and come back to my old 50horse today...... It had good spark, fuel, and compression but wouldn't hit a lick. After rechecking spark for the 5,000th time, and checking timing, I decided to switch spark plug wires and vrooom, it immediately...

    '72 50hp won't run???

    I've got good spark on the spark tester, 150-155psi on both cylinders, checked timing with timing light and it's good, too. It has been huffing and puffing yesterday, but I can't get that out of it today, even with fuel-oil mix in the cylinders or the carb throats. I have no idea why this...

    No pulse from intake manifold for fuel pump?

    Need some ideas pretty please.... The motor is a '72 50hp johnson that I just rebuilt. It has 148psi in one cylinder, and 151psi in the other. The timing stop screws weren't tampered with in any way and I'm getting a great 7/16" spark or better. Brand new OEM flywheel key. I used an OEM...

    '72 johnson 50hp rod and head bolt torque

    I'd really appreciate it if anyone knew offhand the rodbolt and head bolt torque and torquing pattern, and the direction of pistons and rods as far as oiling hole direction-if there is one. Thanks, JBJ

    '72 50hp New rings or not?

    Guys, I'm having to put a new piston/rod/rod bearings, and crankshaft in my motor. If this motor runs out as good as I hope, I plan on keeping it for myself and hopefully using it for many years. Question, is it wise to replace the rings on both pistons while I have it apart and it's easy to...

    '84 merc 25xd clutch and gears question

    Howdy guys, Question: How does one remove the spring loaded clutch dog on this motor? I've got the prop shaft and such out, of course. #2 Forward gear is holding fine, but reverse is ratcheting in the water although it goes in smooth on the muffs with no water resistance. Is it...

    Looking at used outboards....

    I am just noticing a pattern in my used outboard purchases lately, in the 50-65hp power range. It seems there may be some deals to be had by looking at old rottten fiberglass boats with motors on them. If you can find one that hasn't been run in long time (i.e. the registration sticker was...

    1972 50hp updated

    I found the source of all my probems: The flood had put crud into the block which siezed both rings into the piston grooves. I also found very slight pitting on the bad piston's crank journal and rod/caps. It appears I will be needing a crank, a rod, and a piston with rings and this should...

    1972 johnson 50hp-- several questions...

    Background: Bought motor, trailer, boat, with all papers for $100. Motor was in a flood at one time and never restarted. Hasn't been since about '87. IT is hydroelectric shift. Motor was a little sticky but after a little wd-40 in the plug holes and practically no effort, it...

    '72 mercury 9.8hp Proper rubber mount rem. method?

    Guys, What is the correct tool or procedure for taking the midsection (exhaust tower) loose from the transom swivel bracket? I am needing to get it off without ruining the rubber shock mounts. I know I have to get the snap rings off, but they only come OUT and seem to be a press fit. I've...

    Made it back on a 1/3 of a drive pin!

    Well, like an idiot I didn't have my extra drive pin and sure enough, hit a submerged log chunk or whatever IN THE CHANNEL! It's only a 101 degrees here and I wasn't looking forward to a mile paddle. I was hoping to use my leatherman to get a screw or nail out of a tree with a yo-yo stick on...

    Watched a good movie.....

    They were giving away free HBO for 3 days on Dish Network so I scanned through to see what was on. I noticed a movie called Temple Grandin...... it sounded hokie and tree huggerish so I looked at the info and noticed it had one of my favorite female actors in it (Julia Ormond) so I turned it...

    What product for UV blocking on resin?

    Guys, I'm nearing completion of the fiberglassing/epoxy resin phase of my wood boat and am wondering if you could recommend a product and supplier for blocking the UV light so the resin wouldn't deteriorate. I'd like to keep the whole boat clear (no paint even on the bottom). I used U.S...

    Poulan weedeater...fuel line fix????

    I despise the @#$@$ fuel lines on these danged weedeaters. THey make these things knowing that the crappy fuel lines going into the tank are going to rot (apparently even if you keep them out of the sun in a garage) and most people are going to just buy a new one. I'm thinking of putting...

    1976 55 evinrude......good model?

    I was considering a '76 55hp evinrude for my pontoon barge. Does anyone have any experience with this motor? I looked on the parts diagrams and it appeared to be a normal mechanical shift, which I liked. Any insight into the reliability of this model would be appreciated. Thanks, JBJ

    Is the steering system for MErc compat. with OMC?

    I have a merc 65hp from '74 on my 24' pontoon and had the stupid question: Will the steering system on my barge fit an OMC from around '76, or do I need not only controls, but a whole new steering system? Thanks, JBJ

    Stain before epoxy and other q's?

    Guys, I did a search and couldn't really find my answer, so....... 1. Is there a stain I can use to stain my plywood boat before I apply epoxy resin? I'll be leaving part of the boat unpainted so I can see the wood. I just plan on painting the part below the water line. 2. Should I apply...

    Finding schools of crappie in shallow lakes?

    Anyone know of a way to find schools of crappie in shallow lakes? My lake has lots of cypress brakes and scattered cypress trees and averages about 6ft. deep, with lots of aquatic vegetation although it's not bad in the winter and spring. I've found myself catching plenty when they're biting...

    '75 merc 650 problems solved--thanks

    Just wanted to mention that I finally got my confounded 3-cylinder 650 running pretty good. It was bogging when loading the trailer and Faztbullet mentioned the carbs were lean----he was right. I was also getting aluminum build-up on my plugs and Faztbullet said it was detonation---he was...

    Don't miss out on this c-list deal!!!!!

    THis boat needs some work, but the merc just needs a spark plug....... :):) I just had to laugh at this one. At least the seller is not so crazy as to ask too much for it! I think that one spark plug thing is a little optimistic!!!!:eek: Thought someone else might get a laugh at this one...
