    Thinking about selling my 90hp 1986 Mercury inline 6

    Neighbor took his 4 yr old four stroke outboard at the end of last season for a tuneup so he would be ready to go this season. Oil change, filter, plugs, lower unit change etc.....typical motor service....cost him almost a thousand dollars ! New motors are expensive to start and keep on being...

    Thinking about selling my 90hp 1986 Mercury inline 6

    Unless your two stroke is dead and needs replaced, the cost of moving to a four stroke is not worth the expense. You will need to live a loong time to save enough fuel to cover the cost. In fact, even if fuel was only two bucks a gallon, don't think you can recover the cost if a new motor.

    Mercury 850 85hp. Good engine or stay away?

    Test holes are drilled on the inside and do not go thru, just deep enough to get into the wood skeleton....if the chips are wet and dark colored there is rot, but if the chips are dry and normal wood color your safe. Holes can easily plugged with marine sealant. Small holes of a 1/4" are all...

    Thinking about selling my 90hp 1986 Mercury inline 6

    I considered getting a new 40 ho four stroke to replace my like new older two stroke. Compared the mfgr claims on fuel economy for both. The old two stroke uses 2 more gallons of fuel per hour at wot than a new four stroke, so at 4 bucks a gallon, how long will it take to recoup the 9K it...

    Mercury 850 85hp. Good engine or stay away?

    Unfortunately these boats always rot from the bottom up so near the bottom of the hull is where you should test. Lowest point on the transom wood and same with stringers, closest to the bottom. If garaged that is a big plus, just be sure the structure is sound before taking family and friends out.

    Speedometer Not Working

    I understand, I am the same way, it bugs the hell out of me when something doesn't work as it should. That is why I suggested replacing that Speedo with a more useful gage that actually does something usefull. Sorry to say, but those pressure Speedos are always an issue. I had to work on mine...

    Mercury 850 85hp. Good engine or stay away?

    You have been concentrating your efforts, what about the boat itself ? 74 is quit old for a glasser, be sure you check the transom and strings for any rot or soft wood. Looks don't mean much if the skeletal structure has bad wood. Good luck !

    Speedometer Not Working

    Find a different speedo, those pressure units are very inaccurate below 20 mph. Replace the Speedo with a more useful gage to fill the space then use or buy a sonar unit with GPS. Your speed will be very accurate from 1 mph on up to infinity....even if you get it unclogged or replaced, it will...

    Trolling Walleye. Any insight?

    Colors seem to change every year and it all depends on where your fishing and what the fish are used to seeing. Over my 40 plus years of chasing walleye on lake erie....things change...certain colors are staples, but when things get trickey, you need to experiment.

    Bypass oil injection 2000 90ELPTO

    Good to know, my last OMC motor was from 1988 and it did not work reliabily, so mechanic showed me how to bypass it. Motor did not idle well after. Had two that were problems, enough for me.

    Trolling Walleye. Any insight?

    All depends on the walleye and what they are used to seeing and chasing. Here in my end if Lake Erie, I use crawler harnesses trolled and have caught more walleye on crawler harnesses than any thing else. Guys spend big buck's on gear to catch walleye, but when it comes to simple and...

    Replacing water pump impeller for first time

    Be sure to coat the impeller and housing with some silicone grease before assembly, makes turning the impeller much easier and adds some lube on initial start.

    Fuel water separator install

    Of more concern to me....how is the water getting in ? Check where you buy your fuel ! Often folks are getting bad fuel when they buy it if the vendor doesn't take care of his stuff. Years back I had a water issue on a boat I had recently purchased. Water was getting into the fuel tank...

    89 Yamaha 70hp two stroke opinion

    I have a Mercury oil injected two stroke motor.....when starting cold, I let it crank a few times to get the oil pumping, then choke and start...the smoke tells me the system is working properly. Smoke goes away in a few minutes. You should have a quick connect on the fuel line, I unhook mine...

    1962 evinrude fastwin on a 1236 aluminum john boat motor height.

    A 25 hp motor would be an accident looking for a place to happen, way to much ! If an accident were to happen, you would be sued for negligence! 10 hp would be maximum if the boat is rated for that much.....
