    Recommended lower unit maintenance?

    I have the lower unit on my Honda 8HP BF8AM pulled partway off while waiting for a new impeller and gaskets for the water pump. I cleaned the surface where the lower gasket seals, cleaned the metal cover plate, cleaned some debris from the water chambers (including getting mud out of the...

    Use digital contact tach to test RPM?

    I can borrow a CenTech (Harbor Freight) digital contact tachometer. This has a mode where you put a wheel against the side of a rotating shaft and it then measures feet/minute. The flywheel on my Honda BF8A is mostly exposed, and it is easy to touch the side of it. I measured the...

    How to measure engine RPM?

    for an 8HP 4 stroke Honda. I have seen few posts of what type of test tach to get. I did find a few references to tinytach.com, however their site says the battery is good for 5 yrs (maybe more), and can not be replaced - don't like that idea. I haven't found any other references anywhere to...

    OK to use clear vinyl fuel line temporarily?

    I can't easily find the grey opaque fuel lines for the inside of my 8HP Honda BF8A, that run from the fuel connector to the pump to the fuel filter to the carb. I will eventually be at a boat supply store to get the proper hose, but not now. It seems to be 3/16 ID. I want to replace it as the...

    Honda 8HP carb issue (I think)

    Motor is BF8A, approx 1993 or 1994 year. I had it tuned when boat was launched in July. Carb had been gunked up as it sat unused for a few yrs by prior owner. Ran OK at first, then I started having hard starting. Later in summer, started stalling when put in gear. I've used StaBil in all...

    Stalling when put in gear, Honda 8HP

    Approx mid 90's vintage BF8Am. I purchased boat/motor in spring of this year, engine could not be started. Local shop fixed, carb was gunked up (engine had not been used for about 2 yrs, perhaps a bit more). I first launched boat (23 ft sailboat) in mid July. I've had problems with hard...

    Advice: debug Honda 8HP charging system

    My BF8A (manual start) has poor (like 0.1V) voltage from the charging plug. I checked the V at the wires before the fuse, same result. This was after having tried to charge a more or less discharged battery. Cable to battery was disconnected while I tested the V. I have a shop manual, and...

    25 pulls to start 8HP Honda?

    This is a BF8A, approx 1991 to 94 vintage. New to me. Motor wouldn't start first time I tried it, and I had it serviced. Apparently prev owner had not used it in maybe 2 yrs, so carb was gunked up. They cleaned it, put in new plugs. It has been very hard to start, takes a good 25 or 30...

    Ran engine dry briefly - should I worry about impeller?

    This is a 8HP Honda 4 stroke, BF8A, about 1993 or 94. I bought boat/motor a few months ago, and had motor in shop (turns out PO had not used it for a few years, carb gunked up). After I put on the boat, I wanted to make sure it would start - no point in stepping mast on 23 ft sailboat and then...

    Easy to remove and replace flywheel on BF8A?

    I have a used BF8A, 8 HP 4-stroke, that I got with boat a few months ago. It is probably anywhere from a '91 to about a '94. Has no spark. Kill (safety) switch seems OK - when disconnected and checked with ohmmeter, it goes from open to closed circuit (though I forget whether it is open or...
