    How much does a 1985 Hydra bass boat, 18' w/150 Mariner weigh?

    I'm looking at taking over a dock with a lift that can support 4000 #'s. Thanks... Gary

    Mercury fuel problem...

    A friend just posted this on the wrong forum. (fishing forum) Here's his question. I'll post a link to here on that forum so he can view the answers. I've always come here for motor problems. He's a bit of a clown in the way he posted this but here it is. xxxxx Let's say that some guy, his...

    Hooking up trim gauge... Evinrude 1978 115 HP engine.

    Notice the two wires from the working tilt and didn't see any markings on the wire. Guessing it's some kind of variable resistance. Anyone know how to hook up a Johnson trim guage I picked up? Point to an online wiring gauge?<br /><br />Thanks... Gary

    Tachometer checkout question...

    I have stopped in here a few times of late and got some good answers sometimes and I thank those who took the time. I have a 1978 115HP Evinrude 4 cylinder. Great compression. Posted about a missing starter bolt letting exhaust out, got no answer but the new bolt seems to have fixed it. <br...

    1978 115 hp Evinrude and found lower bolt out of starter...

    Seems exhaust was coming out of there too... I replaced bolt and no more leak. Is that normal to have a port that bolt passes through? If so what kind of damage could I expect from this? If it's a problem what is the problem?<br /><br />Thanks... Engine seems to be running fine and compression...

    Have the 1978 115 HP Johnson getting in shape... Couple questions about it...

    I've ordered new Johnson OEM coils instead of the Sierra's from dealer. Mine are quite cracked and as suggested earlier this week probably either a problem now or going to be one. My question just looking the engine over tonight is what are the blue modules actually for on either side of the...

    1978 115 hp Evinrude and it acts like it has bad gas every so often...

    Once it warms up... I check compression after the first time it did it and had 125+ on all 4 cylinders. What would be the most likely culprit and what would be a way to check it. Seems to run fine at home on the hose. Ran fine for about 15 minutes tonight before that waaaaaaah slowdown. Starts...

    Evinrude 115 HP 1978 outboard problems... (Very edited...)

    Just fired it up and had some problem getting any water out of the bleeder hole. Water pressure went up about 20 lbs when on top speed of the idle. I Cleaned the **** hole and it started dripping. Temperature on the head at the sensor was 106 on one side and 124-138 on the other. Seems I have a...

    Gas tank vent.. Suggestions...

    I have an aluminum tank I bought for my pontoon and it has a fitting for a vent and I want to put one in. Should I just put the vent at the hole or run it a ways from the tank for some reason? What do you suggest I buy for a vent piece. I saw some stainless ones tonight with just what looks like...

    Thermostat change out... Do you guys use gasket sealer?? And...

    This is a 1978 Evinrude 115HP outboard. I didn't notice any gasket sealer on either thermostat housing I took apart recently. I have a feeling that you don't need it unless it's just for holding it in place for assembly ease.<br /><br />Does the plate between the outer housing and the powerhead...

    1978 Evirude runs but very coolly..

    I fired it up for the first time this year to see if it had any fuel problems my pontoon had. It has a vented fuel tank so I guess that's why it's OK. I put fuel stabilizer in both last fall. I seem to have a bit of a problem staying at an idle but it is almost like it isn't warmed up. I'm...

    Been bothering you guys with a bad gas problem... Geeeezzz

    Seems my boat ran fine in the yard but once I put gas into it on the way to the lake and even though it sat for another week before I actually took it out it was bad gas. Apparently dipping it on a launch ramp seems to bring it on and running it around on the lake with a different tank hooked up...

    Is rebuilding the carbs much of a job on an 89 88 HP motor?

    What are the pitfalls?<br /><br />Can I unbolt them from the motor and just bring them back without the boat to work on? I haven't found my beloved (NOT) Clymers manual yet. I seem to have misplaced it. (the wife might have thought she did me a favor by throwing it away after she heard me...

    My 89 88HP Johnson now won't stay running...

    I just finished figuring out why it was overheating after changing thermostat and water pump. Blowing out the heads water passages turned out to do the trick. I then proceeded to do the Sea Foam thing and blow out the carbon. Everything was fine. I even did it a couple times as I had never done...

    Warning horn on 89 Johnson is not thermostat..

    Unfortunately my dealer told me I had everything in the package after looking at it. No having done it before I didn't notice it only had one plate gasket, one thermostat cork gasket, one plastic valve and the rest of the stuff was there. I decided to go ahead and change both stats using the...

    Warning horn on 1991 88 HP...

    Was getting ready to take my pontoon up to the lake when I test ran it again. This time it ran fine for 5 minutes, water shooting out of the **** hole very hard but as stated the warning buzzer went off. I'm an air conditioning guy so I quickly (well 5 or 10 minutes or so) went and got my...

    Found field added blue and green wire going to engine...

    I have an 1975 Harris 28 ft pontoon and was rewiring the entire dashboard. pulled out two unused insulated quick connect wires. One blue and the other green. The seem to disappear into the taped wiring harness once they enter the engine compartment on the side the main red harness it at. They...

    Got starter to turn over... Now won't stay running..

    I changed gas lines with my pontoon which does start and run as well as changing the spark plugs. (Figured the gas line had quite a bit of known fresh fuel..) Pulled the screen out of the fuel pump and it was clear. Not really sure which way to go. Starts for a few seconds and then dies. Fuel...

    1978 Evinrude running quit.. No starter or choke...

    Just quit and all of a sudden I couldn't turn it over or even press the key in for the electric choke. Start relay will run if the starter if jumped in the control wiring there. Solenoid is not out. It makes the circuit for you and turns motor over. Is this in the ignition switch for sure...
