That's a great looking boat..302! Probably because it's mine..lol
Always looking for kaama information, never know when you will have to do repairs and having a schematic helps. If you buy one let me know and I'll send you what I have.
Have not had to do mine yet,just keep the oil changed and greased.
All the drives are the same except for the gearing ratio,which are changeable. The gears come from Casale..http://www.casalev-drive.com/
The gimbal mount had a bigger plate added on later model boats.
I probably have that many hours on mine and there still good. But then again I don't pound on my boat like some cowboys I've seen.
There is 2-4 guys on offshoreonly.com that have 311's w/kaamas..best place to find information on the kaamas..and a lot of disinformation from people that have never owned one.
