    Merc 9.9, 2 stroke - Need charging kit

    My ~1997 9.9 kicker came without a charging circuit. I'm now finding since I run the kicker about 10X as much as the main that I should add whatever stuff is needed to have it charge my main batteries. The engine runs beautifully and is very light, I want to keep this one going for years...

    Controls & cables - 4.3l

    Recently I had my boat at a shop, the owner (also the mechanic, parts guy and janitor) mentioned that I should consider replacing my cables and control. He mentioned something called a Commander 4500 which is supposed to be better than what I got. He also mentioned that my cables are bad and...

    Alignment...what could have happened?

    Last fall I pulled my A1G2 leg off my boat, the removal was a bit tough at first but the shaft slid out smoothly, no sign of binding anywhere. Last week I tried to reinstall the leg, I tried to slide the alignment bar in and it would not slide into the splines (made it thru the gimble bearing...

    Retiming 1993 4.3 4bbl after intake gasket change

    So I think I caught the source of my antifreeze leak, seems the last fella that did the engine rebuild did not put any silicone around the water passages in the intake gaskets, there was a slight leak into the intake which a new set of FelPro gaskets took care of. My question...as I had to pull...

    Alpha 1 EZ steer connection

    I'm in the process of fabricating an EZ steer from my Alpha 1 to my 9.9 kicker. The mount on the kicker is dead simple but I am scratching my head on options for the drive side. There are 4 12 sided bolts holding the top of the upper gear housing on but their position is not optimal and they...

    4.3 using anitfreeze

    I have a ~1993 4.3l 4bbl with Alpha 1 leg, the engine is close loop cooled (block is full of glycol mix, heat is exchanged with sea water in a small HX) . The engine does not have a serial number (I have checked everywhere and had a few mechanics look as well). The engine was rebuilt a few...

    Merc tilt/trim pump - need parts

    My boat has a 1993 4.3 4bbl engine and Alpha 1 Gen 2 drive, the engine does not have a serial number. Recently the trim pump has been acting up, as of yesterday one of the flared fittings on a hose to the pump started to leak, the fuild coming out was not clear and look a lot like engine oil...

    Alpha 1 Gen II - Shift cutout switch -how does it work

    Can someone please explain when I should and should not have continuity on this switch...the switch is new and the engine shifts smoothly into and out of gear but I thought this was supposed to interrupt the ignition momentarily when I come out of forward gear ( I`m assuming that means momentary...

    4.3 V6 with Weber 4 bbl - won't idle down

    I've been running my engine on muffs and have found it does not want to come back to base idle when I let off the throttle. The engine remains at ~1200 rpm (sometimes as high as 1500) until I lift the cover and manually push the throttle cable back onto the idle adjust screw (roughly 700 rpm)...

    Alpha 1 Gen 2 continuity strap

    So I finally got 4.3 engine back in the boat, took about 3.5 hrs, had to drop the front mounts a fair bit to get the alignment correct (mounting pedestals on the boat were rebuilt while the engine was out so this was expected). Engine fired up fine and after a timing check she is running like a...

    Feeding a cabin heater from an I/O

    I have a 4.3 merc with closed cooling. Recently I got ahold of a cabin heater for the cuddy, a fairly simple unit with a 2 speed fan and a rating of ~8000BTU, the coils are copper with 3/4" copper connectors brazed to them, the coils are stamped as MAWP of 40 psi. Since the boat is closed loop...

    Engine reinstall - 4.3 with Alpha 1 Gen2...any tips or giudance

    So last fall I had a fella pull the engine and leg on my boat (1991 21' Campion Fishing Machine). I'm now ready to reinstall it and I cannot get in contact with this guy. Most other shops won't touch this job so I think I might take a stab at it myself. The research I've done makes it seem...

    Exhaust Gaskets for Closed Cooling System - 4.3

    My 4.3 was pulled last fall to allow some transom repairs, during the pull, apparently someone loosened the exhaust elbows off (I was told it made disconnecting the Y pipe easier). The engine has been sitting on a stand in my garage and today I pressure tested the cooling loop (it's a Merc...

    Setting timing on a 4.3

    I've got a 1998 4.3 4 bbl. I have just finished changing plugs and will soon be changing cap, rotor and wires. I was taking a closer look at the engine and there are no timing marks near the harmonic balancer and no timing mark on the balancer. I've set base timing tons of time on autos but...
