    Spark plugs too clean???

    This may be a really stupid question but I just want too be sure. I put new plugs in my 76 johnson 70hp. I only took the boat out one time for about an hour. Just out of curiosity I pulled the plus to see if they looked even in combustion appearance. They were all very clean and shiny. Should...

    Replaced fuel line and now bog to idle or stop!

    :confused:This spring I replaced all the fuel lines under the cowl. I just got the stuff from the local auto parts store. Last fall I had the boat out and it ran great! Took it out for the first time and it took off great and ran at full throttle for about ten seconds then bogged. It would stay...

    Wallace and Grommets...

    Thought of the British claymation characters Wallace, and his dog grommet. They are always tinkering with inventions. Anyway, i'm referring to the grommets in my thermostat housing. I am replacing both of them (there are two) that the control valves sit in. My original service manual doesnt...

    Another bent prop question on performance

    Hello, i have never posted a prop question before. Last night I was filing off the nicks on my prop and just trying to smooth things out. As I rotated the prop to the next blade I, for the first time, noticed that one of the three blades looked significantly different than the others. U I pulled...

    Thermostat replacement and control valves

    I am going to replace my impeller this weekend and thought to myself why not replace the thermostat as well. Looking at the diagram I see the thermostat and what seems to be two control valves. My question is this: Do these fail? Lots of talk and conviction about replacing impellers frequently...

    Johnson / Evinrude service manual 70hp

    I just purchased a service manual on ebay for my 1976 70hp Johnson. A day later I received a letter from the seller that he misplaced the manual but could send me an evinrude one and throw in a free parts manual. My question: Is it basically the same manual? Will it throw me off when replacing...

    Glastron V-162 Futura

    If anyone lives in Southern IL then you know that most of the lakes are shallow and nasty (dirty). One lake (a little smaller than the others) is fairly deep and real clean. It is Lake of Egypt in Marion IL. In some coves it feels like being up north somewhere rather than in yucky SI. Anyway...

    Starter clicking but not turning motor

    My starter clicks when I turn the key but the motor does not turn. If I keep trying eventually it will turn the motor over but then if it doesnt start and I try again it usually just clicks again. It random but mostly clicks instead of doing what its suppose to do. Is it the starter or the...

    Reluctant 70hp but then vroom...

    I think I already know that the answer to my question is the need for a good carb cleaning but I will describe the symptoms anyhow! I just put my boat on the lake for the first time after buying it. It sat for two years but fired up in my yard almost immediately and idled great. After pushing...

    When does the water start to flow?

    I put my 76 johnson 70hp on the muffs the other day to let her run a little. I turned the spicket on full so there would be plenty of flow. It idled for probably a minute and a half and the water was flowing out of the drain holes and mostly the prop hub. I could keep my hand on the engine...

    trailering with unvented gas tank

    My glastron came with two 6 gallon metal OMC tanks. They do not have a vent screw on them so my question is how do these vent the gas when trailering down the road while the gas sloshes around inside. I would hate to arrive at my destination to find gas leaking all over the place in the bilge...

    Afraid to order wrong steering cable...HELP!!!

    Ok I made the mistake of hammering on the end of the eyelet of the sterring shaft to loosen it up. I dont know if I mushroomed it because I had the other end disconnected on the starboard side. Anyway, I have not given up yet trying to get it out but I am ready to purchase a new one. I dont want...

    leaf spring flat on one side...what are cheap options? I mean CHEAP!!!

    My boat trailer spring shackle is almost all the way up against the trailer frame. The spring is completely flat. I dont see a broken spring but I am going on a camping trip in a week and really cannot afford to buy a set of springs right now. Can I add a leaf (do they sell a cheap kit?) What is...

    77 Glastron futura v-162

    I just got another boat the other day. Found it on craigslist for $700. It was in the same family it's whole life but sat under a walnut tree untouched for two years. I dont see any transom stress cracks and the floors are solid as a rock (I know this does not mean things are perfect beneath).I...

    70 horse sat for two years...what should I do first

    I am buying a boat with a 1977 (I think its pretty close in year) 70hp Johnson. It has sat for two years but was running great when parked. I am buying it from a 75 year old man. Anyway, are there any precautions I should take before attempting to start it. Do I need to squirt stuff in cylinders...

    OHMS Test on electric shift

    I just replaced the coils in my sterndrive with brand new (Old Stock) Coils and the reading is 7.9 on both foward and reverse coils. I thought it was suppose to be between 4.5 - 6.5 ohms. I have a digital voltmeter and set it on 200 in the ohm section on the meter. There was nothing smaller only...

    Simple Question (I think)

    What keeps the bearing race from turning on the prop shaft at the front of the lower unit? Another words a car has a down ward force that keeps the race moving the rollers of the bearing but on a prop the force is foward. Without the downward force what keeps the shaft from turning inside the...

    Coil Seating Properly

    I know I know! Electric shift stringer yuk!!! I just replaced the foward coil that got fried the last time I was out. My question is how do I know that I got it seated nice and flush in the housing next to the prop bearing? There is a small area that it presses into and I did the best I could to...

    Wire Insulation

    Does anyone know what a good substitute would be to insulate the electric shift coil leads in the lower unit of the sterndrive??? I'm talking about where the wire connections are. ie knife disconnects!
