The left side hinge pin om my Bravo 1 has stripped and wont come out. The right one came out. How do I get it out and is the housing toast since its the aluminum threads that have strippef instead of the sstl hinge pin bolt?

Re: Hinge Pin Stripped

I'm assuming that I can use a punch and knock the pin out from the outside through the starboard hinge pine therefore stripping what's left of any threads on the bell housing. I also see where they make 5/8"-18 stainless steel heli-coil for this application that I can use. I'm curious about the longevity of this repair? Also, it is a well known fact that stainless steel bolts will seize within their threads so I question the use of loctite on these pins and ask, why not use LIBERAL amounts of anti-sieze to keep from ruining a bell housing. Mine did not appear to have any loctite and I cannot see how these pins can come out without 100's of ft/lbs of torque turning them out. I'm just curious to hear what the experienced boat mechanics have to say about this situation? Any input is greatly appreciated.

Re: Hinge Pin Stripped

You don't want to use anti seize
Use perfect seal on the hinge pins
Try using some heat on the pin

Re: Hinge Pin Stripped

I ended up using a punch and a large sledge hammer to beat the stripped pin out of the port side of the bell housing. I will now use a kit that is available on another website that utilizes helicoils for about $60 in lieu of having to buy another bell housing for $450. You can drill out the stripped threads with a 41/64" drill bit and insert the sstl helicoils into the bell housing and buy new hinge pins and hopefully they will hold. It will save you $390 so it's worth a try.

Re: Hinge Pin Stripped

If you do use the heli coil drilling that size hole in any material is a pain if it's not fitured square and secure. Also small amounts of anti sieze is all thats required if any at all a sealant will provide the same protection of re-occurance it's just part of the parts working enviroment! Good luck!
