Hy Guys.
Thanks for all the collective advice, the gearbox and motor combination is new, I did,nt think I would have to grease it, as I surmised it would all be factory set, I took it out of the boat and tried it, still noisy but not so much, re,aligned it back to the shaft and that was a little better, have now convinced myself to thinking it is a diesel engine simulator, did,nt want to take it apart, I have bad memories of trying that with an old clock once (could,nt get it back together so that was a No No,) I drilled a small hole in the top of the gearbox casing and injected some grease, doesnt sound much better with a dry run, will give it a test in the bath later. On most of the fishing boats I have owned From 16 ft to 30 ft the gearboxes were noisy, but mostly when going astern, this little gerabox seems to outnoise them all, I think I will stick to straight through on my next boat ( St Jan ) due this week from MMM,.
Once again thanks for all the input
