Hey.

I bought a few days ago the Mariner 30th 30E0 is a model and serial no: 689 S 251 363

It is made ​​by Yamaha or Mercury?
Is it a good engine?

viper;

Your engine is:

30 EO 689-251316 - 1994

From here:

It appears to be a Mercury engine. Is it any good? People have operated Mariners for years with good care and maintenance. In my experience only, the engines worst enemy is the operator. Those that choose to explore their engines and learn at least the basics of the required maintenance and read problems correctly when they happen are the ones who have the engines the longest.

Today I watched parts catalogs from Yamaha, Mercury and mariner. Cylinder block in my mariner 30EO (1994) is the same as Yamaha 30A (1985).

The same is the intake manifold, carburetor, etc..

Yamaha 30A:

I was hoping that the mariner 30A is a newer technology, because Yamaha 30A is almost 30 years. I hope that will be around
