bizzard Posted September 23, 2018 Report Share Posted September 23, 2018 The propshaft where it passes through the gland and tube bearing must be taking a hammering with that set up. I wouldn't be surprised if there's significant wear on both, enough to make clonks and rattles. Link to comment Share on other sites More sharing options...
j04n Posted September 23, 2018 Author Report Share Posted September 23, 2018 it's coming out the water next year for blackening so will have a look then........ although was hoping to get some quieter cruising in before then! Link to comment Share on other sites More sharing options...

You could go down the weed box and grasp hold of the prop and try to pull it up, down and sideways, better stil if disconnected from the nylon coupling, though just remove the shafts half coupling bolts and try and keep the shaft in the same as the running position and yank that end up, down and sideways too. Whilst down the box check that the props boss is not touching or too close to the outer tube collar as that can could clonk when in fore gear.

j04n Posted September 23, 2018 Author Report Share Posted September 23, 2018 thanks. i did give it a good rive around when I was realigning the engine and had it disconnected and it seemed solid. i could also pull the two ends almost together when the flexible coupling was removed. although i was wasn't very systematic. Will probably be worth going through it all again but in a more systematic approach. thought I'd sorted it when I found that the engine was out of alignment, not massively but out nevertheless but unfortunately not.

The nylon coupling coupling was probably fittedv at a later date.. In your first photo check the two nuts and bolts holding the tube stuffing box to the cross plate, the two by the tape measure reel, though they look tight. I can't see properlt.

j04n Posted May 22, 2020 Author Report Share Posted May 22, 2020 Problem solved! I fitted some 15mm spacers under the engine mounts in order to minimise engine movement and vibration but actually the main problem was the weed hatch anti cavitation plate. The handle was 10mm short of the weed hatch cover plate so it was impossible to tighten it down!! I did find the problem 2 years ago but forgot to feedback in case it is of any help for anybody having a similar problem. She sounds soooooo sweet now. Unlike the bag of spanners before. The original owner must have put up with it for 7 years from new!! Link to comment Share on other sites More sharing options...

The anti cavitation plate was rattling around because the handle was not tight to the underside of the weed hatch cover due to being 10mm too short. 3 hours ago, WotEver said: Great It’s only taken you 20 months... you should work at a boat yard ? sorry, been working in Hungary for 2 years so a little out of touch! ?

dor Posted May 22, 2020 Report Share Posted May 22, 2020 On my last boat I had a really irritating metallic rattle. After checking all the alignments and everything else I could think of I eventually took it in to the local boatyard. Their man came out ,lifted the deck boards and listened carefully for a couple of minutes. He then put his foot on a large piece of iron that was alongside the engine bearer being used as ballast. You can guess the rest .... 1 2 Link to comment Share on other sites More sharing options...
