Engine Mounting Bolts?

I dispair.

The engine makes a terrible banging noise when I try and start it up and I think the mountings may have died... how do I tell - no idea!

Anyone want to buy a boat?


Well, that IS weird. It now works, but it does remind me I need to check the mountings are ok. I really ought to do something about them, anyone know where I can find out what they are MEANT to look like?

On another note, I don't seem to be able to find the lock for my bike, this is most cross making, especially as I am planning to cycle to work tomorrow!!!!

it isn't big enough to fit my feet in unfortunately, but I like the write up - it makes it sound as though the daughter, who is selling it for her mother, has just about had enough of the projects her mother takes on! Fantastic.

Two ways to check:

1) Get a spanner that fits the top of the engine mount bolts and try to turn them - they shouldn't!

2) Get a crowbar/wrecking bar and try levering the engine foot up and down on its mount - it should move with a creaking of the rubber of the mount, but not shift about from side to side.

If the mounts have failed, it's a really, really bad idea to try to drive the boat - the whole engine can come off its bearers with consequent damage to everything attached to it. It happened to a mate of mine last year, and he needed a new prop shaft as a result.

Good luck!

Bruce - I think you have to do it from underneath, but I will do that.

I don't have a crow bar.... but I do have an aquadrive which is good in such circumstances. I will have a proper look this afternoon armed with my camera!

If you've got an Aquadrive then there shouldn't be a risk of the engine falling off its bearers. The A'drive has a thrust bearing which means that the push from the prop is transmitted direct to the hull, not via the engine mounts.

In the same way, the mounts themselves should last for ages because they are not doing much work.

Have tried watching the engine running both in and out of gear? Sometimes you can see the movement or vibration which is making the noise (but sometimes not!)

If you do do that, keep well away from the drive belts, of course ;-)
