YAMAHA 70BETO Tilt support levers

57paulimo · 07 June 2019, 10:26

Hi Guys, looking for help regarding the above.
One of the levers that support the engine when its on the trailer is really tight! Ive tried WD40 to try and free it, but without success.
The other side is fine, moves very easily, but I've got to use tools to move this troublesome lever.
Any suggestions most wecome.
Cheers in advance.

They should both move together - they are jointed by a two piece spline plastic joint. They get stiff because of corrosion around the plastic bushes.
If it is a later engine the levers a re made out of a much higher grade metal - the earlier engines tilt levers use to rust away.

You will need to remove both levers and replace the bushes then replace the two part plastic joint.

Depends on age of engine, on mine they move independantly. You could try some heat on them

Thanks for the info Phantom. The manual I've got doesnt really help, and this forum is a great way to share tips and knowledge!

Thanks Roflhat, mine is the same, the port lever has always been a bit stiff, but its slowly getting worse.
Its difficult to see the coupling device as its behind the tilt/trim hydraulic ram, but i might be able to get a bit of heat onto it, then try and get grease onto the coupling shaft.

No it doesn’t. They all move together from 1984 to 2016.
