With the Honda 90 HP outboard you are looking at some of Honda Marine's most advanced technology. This motor is a powerhouse that is based on the Honda Fit automotive platform making it extremely durable and efficient.
Compared to some of its newer competition, the Honda BF90 outboard motor is very light on piston displacement. Straight from the Jazz car, the high-revving engine has VTEC or variable intake valve timing that operates only above 5200rpm, so pushing hefty loads is definitely not what this marine engine was designed to do.
Combine this complexity with BLAST and ECOmo technology and you’ll have to develop a very good relationship with your local outboard mechanic! BLAST increases the air/fuel ratio from the normal 14.7:1 to 12:1 for better holeshot performance. ECOmo leans out the ratio to 18:1 under moderate load conditions, such as when the hull is planing cleanly in the 2000 to 4500rpm range and depending on the throttle opening. Above this, the air/fuel ratio reverts to 14.7:1.
So to get the best from the small, complex outboard motor that is the Honda BF90, it should only be fitted to hulls such as lightweight bass boats that plane easily and allow the engine to rev right out.
