Tohatsu 3.5 2 stroke

That's an ingenious thought. I'll look at the other ring to see if it has a similar split. I didn't notice one.

It looks as if it might have been very tight around the leg, and eventually split from its own tension, like an old rubber band.

I'm surprised if it isn't a replaceable part, although I can't see how it would be fitted.
 
Has it not been split to allow replacement without full dismantling? There's no force on it likely to cause a split.
Very fair comment ! Having read your post there…you may be correct. Although the spit looks a little roughly edged perhaps. I think I remember other similar sized mercury outboards maybe having a split in these bushings…but it was very obviously a clean cut and deliberate split to the eye. Could be wrong.
 
My engine has a very slight oil drip , do I strip it all down or just monitor , also I want to change the gearbox oil , so yes it’s easy to drain but do you top up via the level hole .

It is perfectly normal for a 2 stroke to drip a little oil. . . . It is unburnt oil from the fuel mix.

Provided the gear oil shows no signs of water intrusion when you drain it you have no problem.

Asking here about a different issue because everyone who's replied, knows the Tohatsu 3.5 two-stroke better than I do.
The clamping piece on mine had a badly rusted cross-member which I've drilled out and will replace. In order to get the clamp under the pillar-drill, I unbolted the clamp from the engine and found beneath (surrounding the engine leg) a pair of what look like plastic collars which I suppose alleviate what would be severe vibration if it were metal-on-metal. Trouble is, one has split...


Actually I'm in doubt that it could be replaced without the whole leg being removed from the engine unit, so I'm wondering whether it matters, and what (if anything) I could do to prevent its further deterioration. Has anyone seen this damage before?

It is normal They are split like that. . . . . . . You would not be able to get them on if they were not !
