Cambelt

I'm having the engine serviced and it's been suggested that i should have the cambelt changed.

Is this necessary for a 2003 engine with 350 hours? (Yamaha 225 4 stroke)
or can it wait longer?

Thanks!

You will kick your self if you do not have it done & it then goes! + the mechanic saying I told you so whilst rubbing his hand at the thought of rebuilding your engine!

If you have to ask then you should have it changed

Well the only reason I was asking is that I don't recall having cambelts changed on low mileage and reasonably newish car engines when they get serviced.
I thought that happened on engines with about 50K plus miles on them.

I'm have very little mechanical understanding, but was wondering why a cambelt change has been suggested when the engine is quite new without too many hours.

Perhaps this is the norm for marine engines.

Anyway, I shall definately take the advise and get it changed.

Many thanks

On my 1.7 DTI it's recommended at 600 hours. See how much it's gonna cost, for the sake of 100 you have the reassurance that it's not going to snap

Cam belts on most engines (probably including outboards) are rubber and therefore they perish with age as well as mileage.

I don't know about cars but the cam belts on Land Rovers I work with have a service interval of 5 years in normal use or 3 in arduous conditions (as well as the mileage interval) - and I would say an outboard is probably operating in arduous conditions so 3yrs is not unreasonable...
