    1985 Mariner 25hp Outboard

    I have a problem with a 25 hp Mariner outboard engine. The first thing was it was not charging the battery. I can easily pull start it but it doesn't charge the battery in the least. Now with a new battery it acts the same way. I can pull start it easily but the starter only barely engages when...

    25hp Motor Mariner Not Charging

    I have a 1985 Mariner outboard, serial # A148102. It does not charge the battery while running. How does one check the charging circuits?

    1985 25 HP Mariner

    Have been running a 1985 Mariner 25hp outboard pretty regularly. Sometimes at full throttle it bogs down. When I back off a little it runs fine. Yesterday it was running fine but you could here it sort of hestitate, not continue at the same rpm. I have repaird the spark plug wires with the new...

    1985 Mariner Controller Hookup Problem

    Hey fellow Mariners! I'm having trouble getting a 1985 Mariner hooked up with existing cables and a Quicksilver controller. The shift cable for the gears if fine but having trouble getting the throttle set up right. I have to move the throttle away a little from it's stop point to hook it up and...

    hooking up new throttle and shift cables

    I just ordered the new Teleflex 3300 cables for my Carolina skiff. The boat has a center console with a Quicksilver controller. The cables I purchased supposedly work with 1985 Mariner 25hp outboard I recently put on the boat. It had a newer 15hp Mariner engine that fit nicely but did not have...

    Mariner 25hp Outboard

    Switched motors from one boat to another. One boat had a 15 hp Mariner, a 1993 motor, and the other boat had a 25hp motor, year not known. Probably a 1987 though. Anyway I'm trying to get the remote control working again and can't quite get it right. I switched cables and motors reusing the...

    not sure the year but told 25hp Mariner

    The engine was running a couple of months ago. Fixed impeller and is now pumping water. The engine attempts to fire and backfires when primed. Could this have sheared the key under the flywheel and thrown off the timing. Carburator rebuilt also but with old gaskets. New gaskets on order for a...

    1991 Mariner Outboard

    Replaced impeller, works good with a new one installed. How long will gas stay good, I live in Orlando, Florida. Boat stays in garage while not being used. Was running a couple of months ago. Gas is at least that old. When I attempt to start the engine it backfires. Should I start out with new...

    1991 Mariner Outboard 25hp

    Going to see if the water tube grommet under the power head needs replacing. The bolts are loose but as yet have not removed power head. I'll force water up that tube to make sure before I pull it off. What is the best overall book for outboard maintenance for all users? The serial # is A148102...

    1991 Mariner 25hp motor serial # A148102

    Have taken lower unit apart because unit will not pump water while running. No obstructions seen. Replaced water cover gasket. Unit does not have a thermostat, this model did not have one. Using rabbit ears to test, have installed new impeller but no other parts used. May go get a complete...

    1991 25hp Mariner outboard

    No water being pumped while running, replaced impeller and still have the problem. Use a set of the clamp on ears for the lower unit when testing this function. Where is the thermostat located on this motor?

    Carb cleaning

    Removed carb and cleaned with carb cleaner. Outboard is a 2001 15hp Mariner. Starts with a little help with the throttle but will not idle and runs rough with a lot of smoke. Did not mess with idle speed mixture setting. Did not use new gaskets. Will have to order a kit. Could the carb not be...

    lower unit Mariner 25hp Model A148102

    Have taken lower unit off to install new impeller.<br />Re-installing lower unit has been troublesome.<br />You have to install the linkage to a hole near the top of the shiftshaft. What gear should the lower unit be in for this? Does it matter as long as the clip goes in? I know if the prop...

    25HP LOWER UNIT MARINER

    I installed a new impeller and now have trouble lining up reinstall correctly. Should the gear shift be in forward, reverse or neutral? I can spin the prop either direction with some effort and watch the flywheel spin in any gear. The shift shaft has a small hole near the top. Can this be turned...
