Yamaha 90

Hi lads, would it be risky for me to buy a old Yamaha 90hp, I'm told it's a 1990 model, so it's a few years old now, what's the chances of it being a good buy if it all seems to work ok? Thanks for any help :-)

Most parts are still made. Check compression and run it. They're a pretty robust engine.

Could be good, could be bad. Entirely depends on how it's been treated, compression and how much corrosion it's got.

I certainly wouldn't rule it out.

Sometimes the boat it's attached to actually devalues the engine but the best trial for any engine is get it out on the water and see how it goes so being on a boat could be an advantage if it actually floats and can be used as a platform to try the engine out
They are still available to buy for commercial use only so spares are no problem for the foreseeable future
When right they are a cracking engine you won't find anything better in its class
