One of the trim cylinders is leaking on my '93 volvo outdrive and needs to be rebuilt. Problem is how do you remove them and repair. There is no problem removing the outdrive side but the boat side of the cylinder is reccessed into the back of the boat with no bolt or pin exposed for removal. It is a Volvo 431/dp with a V6. Any help or opinion would be appreciated. The pic shows the end of the cylinder.
