Hi , this is my first post.

I have a Ring 16, with a stepped hull so I think that makes it a 16B. The 3 cylinder Mariner 90 is leaking fluid from the main single tilt ram. The leak is coming from the top of the piston housing. The PTT has needed topping up over the last couple of years: tilt will go up but not down when the fluid reservoir gets low. The circlip has "popped" out before now as I believe it's lost its original memory tension. I also need to make sure the retaining groove that the circlip fits into hasn't become corroded, which may be a major issue.
Has anyone changed the Tilt ram seals before and if so, is there any trick or pitfall I should look out for.

I've managed to get a seal kit from ebay; I couldn't find the seal listed anywhere else. This is the kit, which as you will observe is ridiculously cheap, so I hope it's ok. http://www.ebay.com/itm/271574816831?_trksid=p2060778.m1438.l2649&ssPageName=STRK:MEBIDX:IT

A little history about the rig:

I've had the boat from new, purchased around 1984 which originally came with a Mercury 80hp 4 cylinder. This was changed a couple of years later for the current Mariner 90hp 3 cylinder. The boat was bought from Ron Scott Marine in Tarporley, Cheshire. Ron and his son Paul, ran the business. They had a Ring dealership amongst other brands, but endorsed Ring for their Ski racing exploits. Paul had a successful career racing but not without injury. I believe when the business was sold in the UK they set up a boat yard in southern Spain. Ron and Paul had a great business and always made time for their customers. I saw some years later that Paul had a bad racing accident (not skiing) which was caught on film and is somewhere on this website. The boat they were racing nose dived and completely submerged. This video is all over the internet.
The boat was used all over the North West of England and North Wales, but for the last 10 years it's been kept down in Cornwall and gets used a handful of times a year. I still enjoy the boat and love the area in Cornwall. It's not in perfect condition but it's a testament to Mike Ring that it's stood the test of time and is still a respectable looking outfit.
 
Just to add:


I live in Cheshire so the 300 miles down to Cornwall isn't an everyday journey. I have most tools I may need for the job, apart from a tool to remove the cap piston housing which needs a device with "pin" ends in order to rotate the cap. I saw in one online video that the tool that came with a portable grinder to remove a worn disc, may fit. Does anyone have a dimension that the distance these pins need to measure in order to fit the "slots" the pins need to engage is?.
Also, I believe you need to drift out a pin in the top of the ram housing in order to remove the ram. Can this pin be used again, and which way does it need to be drifted out. Is it then simple to remove the main pin that holds the ram assembly to the yolk of the engine. There is a large slot in the end of that substantial looking pin, so it looks like that too may need a specialist tool.

Many thanks for reading this rather long winded message.

Awaiting your earliest reply,

Rick Barry.
