Hi SB Crew

After almost 8 years to the day we sold our beloved Riviera.

In due diligence we pointed the new owner, Rodney to your awesome site, this forum and these specific topics. In those 8 years we never had the rocker covers off … not saying that is a good thing… but lucky for us we never had a failure. Also never got to install my new SMX sea water pumps.

The best thing we did was to plumb fresh water input after the sea cocks. We used two hoses to a Y connector into half inch pipe… and that was just enough to feed one engine at idle. The anodes lasted for years after that because I always flushed after every weekend. I never understood why salt water diesels never got fresh water flush.. but I grew up with outboards. 

So its back to the ski boat for some wakeboard and tubing fun. Bought a windsurfer and SUPs for the girls.

Happy boating.

Bummer. That tin of gloss almond I tried to purchase via eBay USA for import into Australia failed as a “restricted item” at the Shipping Center. Got a refund but no paint. Not happy. Begging the local Rust Oleum for help with this… but looks like its white for engine touch up or nothing at this stage.

Hi Rob and Stephen

FYI technical@rustoleum.com.au responded with “We can only provide in spray cans.USA hasn’t released bulk sizes yet.”

I have purchased Gloss Almond via eBay in the USA and it has been shipped… will let you know how it goes.Here is the link

I am also seeking some gloss white and will ask technical if how and where… locally.

That is a Top Tip

Thank you Rob and Tony!

We had to machine one of the exhaust elbows but otherwise it all went back together just fine. New bolts and treated with anti sieze goo. The issue was caused by a broken rusted bolt so the task was to remove and replace with new bolts on both engines.

Thanks Tony love your no BS comments. Please refer attached for pics of engine bay and lift mufflers.

Hi guys

Just a follow up. Got the turbo exhaust ports off both engines and replaced with new bolts… had to drill out the sheared bolt and rethread. Here are some photos of the turbos. Lots of corrosion but fortunately both engines are running smoothly with no issues. In this Riviera 4000 the lift mufflers are not far away and not a steep gradient either, especially on the port side… so when engines are off I think the sea water could slop back up to the turbos when the vessel rolls heavily in a wake or waves. Any feedback or opinions on their condition would be appreciated.

I secretly have a wish list to replace the sea water pumps and the turbos… but they are all still working normally. I don’t push these engine past 2000rpm and that gives us easily 22 knots. The majority of the time I am cruising at 1000rpm with my feet doing the steering… slow and steady.

Regards

Mark

Thank you all for your generous feedback.

I have talked Tennis friend Darrin into helping me who hates working on marine diesels for exactly this reason (he just does cars these days). We will attempt to remove the elbow and the bolts and inspect the turbo. Worst case I guess the turbo is replaced and we get a bit sweaty so not the end of the world, just a pain. Live and learn… for example, I have learned to inspect my seawater side impeller, plugs and aftercooler regularly. Slowly getting on top of it all after two years.

I never realised that owning a larger boat would require so much love, time and attention. I have a ski boat in the garage I use once every six months… it starts every time and all I do is put fuel into it and flush it with fresh water when she comes out. I guess though it is kept in a nice dry garage away from that nasty brine!

I will let you know how we go… more story to tell!

Hi SB Crew

Unfortunatley I have failed to remove the exhaust elbow from the turbo.

The second lower bolt simply broke off and the two top bolts will not move at all. I have plied with penetrant several times. Not sure what the next step is, I am wondering if the whole turbo needs to come off… and send the lot to the shop. What is your opinion?

I have attached a couple more photos. By the way I could turn all four similar bolts on the starboard side engine although it shows less sign of rust oxidation.

What is the allen key pin for, alignment? That suggests the turbo has a inner tube that the exhaust elbow slides on to, yes?

If the turbo needs to come off do you have any tips on removal of oil and coolant lines?

I am thinking if the turbo is too rusted with are bolts stuck inside it may needs to be replaced?

Thanks for your feedback

Mark

[Mark Theyer]

Thank you for the feedback. The performance of both engines is good and appears normal with no black smoke at any time or on the plane.

May I ask, what is the general life of these turbos and are there any signs or indicators of wear or when they should be replaced. For me I would replace with your brand new turbos since it would likely cost me as much or even more to have them reconditioned here in Australia.
