    New to me Honda BF75S shifter stuck

    I just picked up a Honda 7.5 hp BF75S serial # 1705778. I've owned many outboards over the years but this is my first Honda and also my first 4 stroke. I don't know if I'm doing something wrong but I can't seem to get the shift lever to move. Is there a trick to this? Is there a lock out feature...

    Is there such a part???

    The fuel pump on my 1966 9.5 Johnson is the type that is mounted directly to the block. I suspect the pump may be weak and I'd like to experiment with a Mikuni snowmobile pump to see if it would work. My question is whether or not a plate with nipple to attach a pulse hose exists? The part I'm...

    Plastic straw in crank case J110TLCCA

    I was fogging my 1988 Jonhson 110 (J110TLCCA) and the red plastic straw that fits on the aerosol nozzle blew off and went right into the motor. The piston was all the way on the downstroke so it looks like the straw found a port in the cylinder wall and went all the way into the crank case. Just...

    Fuel pump repair 9.5hp

    I have a pair of 9.5 hp motors, a 1966 Johnson and a 1972 Evinrude, both motors die after 10 seconds or so at wide open throttle. I can keep them running by squeezing the fuel line primer bulb when this happens so it seems like I have a fuel delivery issue. I recently extended the fuel line so...

    Good deal on a couple of old 9.5s but...

    I bought 2 outboards this morning for a hundred bucks each, a 1966 Johnson 9.5 (MQ12A) and a 1972 Evinrude 9.5 (9222M) The motors are complete, unmolested and are in extremely good condition. Prior to actually seeing the motors, the plan was to make one good one out of the two but given their...

    Merc 4.5 hp starting procedure????

    I recently aquired a 1981 Merc 4.5 hp outboard that I was told "Needed a little work", the seller said it was running but not running well and he had not used it in 3 years.

    I just bought this 87 8hp Johnson (CJ8RCUD) and the first time I ran it I discovered that it wouldn't turn off even with the lanyard clip removed.

The main problem as I see it would be cranking the motor over since...

    Old 2 stroke oil okay to use?

    I have aquired 40 unopened bottles of Nissan 2 cycle outboard motor oil but it is around 15 years old. The oil has been sitting on a shelf in a heated warehouse all these years and I was wondering if it would be safe to use? I can see no visible separation in the oil if that makes a difference.
