They have been shipping the all metal camshaft pulleys for the Honda BF20D outboard, to destinations as far abroad as Canada and Finland.
Plus I had a query from an Australian BF20 owner.
Thank you I have the same problem. I will order 2 aluminium pulleys. No more bent valves for me.
I have two BF20 motors on a 40' Cat. One just stopped working after about 25hrs.
I removed the plugs and could feel no compression.
After removing the cam belt cover I found the belt had fallen off and the cam pulley was loose on the shaft.
Turned the cam to close the valves and re checked compression with finger.
Still no compression on one cylinder.
Removed head to find bent exhaust valve.
Replaced valve and pulley and now OK.
Even though it was only 1 year old and still under warranty I could not wait for the repair so I had to fixed it myself. I got the parts under warranty.
