Donglai, I was having the same problem last year with my M17... Jerry's first recommendation was to whip up some epoxy and spread that around the pin on both sides (goop up one side, hammer it over to the other side to goop it up also and then line it up flush) and let it dry for a day or two. I believe this "thickens" the pin and keeps it where it belongs. If that doesn't work (and it worked for me so far) then you probably need to replace the pin. He said that you have to knock the new one in while knocking the old one out... I am sure there is a trick to that as the centerboard may want to fall somewhere in there. I guess if i were to do that i would hammer hard and fast to make sure the hole stayed lined up throughout... perhaps there is another trick to this... But i would try the epoxy fix first... it worked for me (so far)!

We had a great time on the water and did some beach hopping. I encountered two major issues. 1) My Honda 2hp is burning oil and start to smoke badly when I ramp up the RPM. We had to shut it off to let it cool before turning it back on again. It worked fine afterwards in speed just above idle, we cruised at 2 knots or so with the motor all afternoon. Any ideas on what could be causing the oil burn? Oil also leaks out of the exhaust pipe if I ramp up the engine. 2) My centerboard pin almost fell out. After I towed the boat out of the water, I saw that the centerboard pin is stuck out way on one side. I could push it mostly back in with just hand force. I don't want is to sail along and have my centerboard fall out on me next time we go out. I'd appreciate any idea or suggestions on these two problems. Thanks!
