Boat Type: glastron spirit 6.5
Recently bought a '78 Glastron Spirit 6.5. Really love it and got a good deal, but one irritant: in heavy seas swing keel will begin to fold up when bow is high and clank a little when boat goes over the swell and bow drops.
Found an original owner's manual for my boat online, but it was published in '79 and my boat is a '78. Anyway, the owners manual says the boat is equipped with an L-shaped locking bolt located on the port side of the keel trunk which can be hand tightened when the keel is down to keep it down in rough weather.
I looked and found an eye bolt which has a lock nut on the end. I was able to loosen the locknut.(the boat is on the trailor in my yard) but the eye bolt doesn't seem to want to loosen and it looks to me like this bolt is actually the pivot bolt for the swing keel- so I don't see how this could be the one the owners manual speaks of. In any case, the dangers of messing with this bolt are obvious if it is the structural connection of the keel to the rest of the boat.
I figured the date discrepancy wouldn't make any difference, but maybe this friction bolt was added after '78.
Can you shed any light on this or make any suggestion about where I could possibly find more info?
The thing is, I don't really know if this banging of the swing keel could cause any real problems or not, but it can't be good for the swing keel cable or the shackle where it attaches to the keel.
If I lost that, I'd have a hell of a time getting the boat back on the trailor.(I'm keeping it at home for now)
Thanks very much, Jeffrey Kurtz
