    1999 BF8 Manual start Strange Whirrring sound from starter case

    Motor runs well. Has a whirring sound coming from under or in the starter case. No knock or rubbing just a constant whir. Used a stethoscope to try to find the source and it seems to be loudest from the area of the breather cover. The other points on the starter case seem not to be as affected...

    Have seen quite a few problems with cooling these engines. Seems like the cooling system tends to clog at the thermostat. Not always an easy job to remove the manifold. Wondering if this is a common occurance with these engines. Should I just leave the thermostats out? I live in San Diego so...

    I am trying to decide whether or not to rebuild this motor or switch the powerhead. I have not rebuilt powerheads before but seems like a winter project worth while. Looking at the parts diagrams for the piston and crank shaft I see no bearings where to connecting rod joins the crankshaft...

    Went out last week and heard and felt a bump which it seemed was coming from the lower unit. Happens at higher speed (not at slow speed). Began to feel and hear it more and more. Figured it was the shift cable out of adjustment as I had removed it when doing carb work. Started to happen more...

    Honda BF75 and BF100 What is the difference, besides 2.5 HP?

    Is it just a carb swap? I have a BF 75 with a bad lower unit and a BF 100 with no compression. I plan to switch the powerhead from the BF75 to the body of the BF100. The BF75 is a long shaft,nasty looking motor while the BF100 is in beautiful condition(except for no compression). Will the BF100...
