We have a lost of units in service

The Drives Will Do 1000 hours if you swap them side to side at 500 hours to evan out gear and clutch wear. We Run Castrol SAF-XO Change Every 200 Hours. Drive Shower Are A Must.
But pinion gears do wear and are pron to fail on the SP units.
The TRP is a good drive.

Engines are good, they do crack pistons but not to often.
There of lots of mods that can be done on the engines to aid service life.
We run volvo vds2 oil and now have changed to vds3. units have from 1000 to 3000 hours on them, oil change every 200 hours. when striped after 2500 hours still got honing marks in the bore and not bearing wear.

Cheers Josh

Biffer, we have thousands of 6 cylinder Landcruiser diesels here so the engine side is not what worries me although I think the fuel injection and pistons are different as well as the obvious cooling and exhaust bits. Was thinking of the fuel filters, oil filters, fresh oil and coolant. The air cleaners look clean.

The drives on the other hand as rare as hens teeth here. I have never seen others.

Martini, the skeg is cracked off one of the drives and bent on the other so was thinking of removing the drives and sending them to get welded and straightened. If you spin the prop they feel pretty smooth so I was thinking just an oil change and a repaint would be on the cards. As they have 550 hours, we will as you suggested, swap sides when they go back on. I am debating stripping them down and replacing the bearings as well as inspecting the rest of the drives as this will result in the boat being out of the water for a lot longer than we want. Also will probably add drive showers as on my other boat.

We started the engines today and they started easily and idled smoothly. Will check the hose pressure for the mixing elbows but as it was a salt water boat, I think we will be needing stainless ones sooner or later.

How about water pumps. Are there impellers in the drives or just the engine mounted water pump?

Biffer can you let me know how much for two stainless elbows?

Is there anywhere I can get a workshop manual?

Thanks guys for the help, not sure what I would do without this forum.

don't strip them down till you need to, mig the skeg back on but put wet clothes over the gearbox and down the exhaust, stainless exhaust elbows are 500 each, water pump is below the fuel and water strainer, take the pump off, 2 x 17mm bolts and 2 x hoses, much easier, filters from motor factors, one of my boats had 2.5k hrs on her without any major stuff and i think she's still going strong, if you can get at the turbo oil feed pipe change it for a teflon one or clean it out, if you don't use good oil you get carbon build up in it and it will starve the turbo, pop!, just to rub it in i have 3 spare legs laying around over here

Biffer, if you see a blue Range Rover outside your place and the spare legs are gone ..... it wasn't me ..... could be a loooooooong drive to Sydney Australia though.

I wish we could get spare drives here. I guess the long term aim would be to do that and probably need to source them from over there.

Thank you so much for the tips, will let you know how I go.

Biffer, or anyone else for that matter, would you be interested in selling me a complete drive?

Hi,
FYI I sold (through our brokerage) a Ribtec 890 SX for export to Papua New Guinea. It is likely, that this is the boat we sold. It belonged to a guy who kept it with us on the Dry Stack for several years. If you need to know any of it's service history and background, then let me know. BTW, has it still got a frog motif on the rear of the tubes?

It certainly still has the frog. I imagine there are not too many 890 SX's exported to Papua New Guinea with a frog motif, so this must be the boat.

Anything you can tell me about the boat would be most appreciated. Waiting to find time to give it some maintenance and for some warmer weather in Sydney to take it out.

I love rib.net, it is amazing what you find.

I'll send you the photos we have of the boat when we were selling it. It will be interesting to see if it's changed much. The new owners were going to get a bimini made for it - wonder if that ever happened? Frog motif is unique to that boat (previous owners nickname was "froggy") so it must be the one. As they say - small world!

I'll PM you the history of the boat as we know it, but suffice to say that it was always well maintained and serviced - although not always loved!

Anyway, have fun with her!

Oh and the dials and guages you've ordered from me will certainly fit that rib as we have already supplied the ignitions on it from the same stock.
