      October 27, 2022 at 2:49 am 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.…

      August 16, 2018 at 6:47 pm Hi guys What engine paint should I use to tidy up some sea water leak rust stains etc on my 1997 6CTA Cummins 450’s? I’d prefer brush on rather than aerosol due to the engine room confines and fiddly nature of the touch ups. Cummins South Pacific quote beige paint in oil 3885999 and water 3885925 based.

      May 22, 2019 at 8:37 pm I think the 6CTA is a whiter paint is it not over the 6BTA?

If not I guess you are down to a auto paint shop and get them to colour match and mix for you.. I have done this in cans before.. Steve

    • Tacho Needle

      January 30, 2017 at 9:31 pm   Hi SB crew I have a 1998 VDO Cummins Oceanline Tachourmeter on the starboard side that was working fine but is now going off scale (over 4000rpm) when I reach around 1000rpm and it then never recovers. I tried a swap test and it is the tacho as it does the same on the left engine. Is it stuffed or is there an opportunity to recover? I cannot source any replacement for this old tacho… Regards   Mark Theyer
