300 HP Yamaha OB

Hi,

I'm looking for installation drawings concerning the 300 hp OB Yamaha.

The boat is an high speed defence boat with 4 x 300 hp.

This is an updated version of the NAJA ASD sold to Gulf country in 40 units (120 OB engines).

If I will not receive available informations concerning this engine, I will change manufacturer!!

Help please....

Thanks

I'm always mystified as to why it's so easy to get hold of proper installation / CAD drawings for inboard engines - particularly diesels - and all but impossible to get the same for outboards. I share your frustration!

The same can be said for outboard performance / consumption data.

Sadly, I can be of little help. The only success I've ever had has been to approach my local dealer who was able supply hardcopy only.

Concerning diesel engines, I had never problems with CAD drawings installation.

For the OB engines I have the consumptions and power vs power measured during sea trials of the NAJA ASD. This boat was equipped with 4 x 300 hp Johnson not more in production....

Yes, but I am thinking the dealers might be forthcoming with the data you want.

Also, try here. http://www.outboards-direct.co.uk/aw...elst.asp?rip=8
