Basildefarmer Posted March 30, 2020 Report Share Posted March 30, 2020 (edited) Hi I wonder if the more learned amongst you could help me with identifying my engine other the it's an ST3. The info panel on the engine states: No 3400235ST30-29 Unit 5188ST3MG85 Thanks Edited March 30, 2020 by Basildefarmer An omission Link to comment Share on other sites More sharing options...
RLWP Posted March 30, 2020 Report Share Posted March 30, 2020 (edited) What do you want to know? Hmm, Serial number says it's an ST3, Unit number says it is a marine unit with a gearbox Richard Edited March 30, 2020 by RLWP Link to comment Share on other sites More sharing options...

Basildefarmer Posted March 30, 2020 Author Report Share Posted March 30, 2020 Hi Essentially I wanted to understand the lettering and numbering. Which I think you've answered for me. Any idea what the 0-29 on the No refers to my any chance. Thanks Link to comment Share on other sites More sharing options...

I'll take a risk because I forget when the date changed ends in the number - it was built in 1979. The ST3 you worked out, M for Marine, G = with a gearbox. You can find SR engines labelled MGR where R means with a reduction box Richard 7 minutes ago, Victor Vectis said: I'd like to know who this Mabel is.

bizzard Posted March 30, 2020 Report Share Posted March 30, 2020 (edited) 1979, Possibly a Hurth gearbox. We have a boat here with a STW3 of around 1979 supplied with a Hurth box. Sorry no umlaut for the U Edited March 30, 2020 by bizzard Link to comment Share on other sites More sharing options...
