BRP stands for Bombardier Recreational Products and it offers Evinrude
and Johnson outboard motors, personal watercraft, snowmobiles, ATVs and
sport boats. It is NOT an affiliate of Learjet, that´s a different
Bombardier from which BRP was spun off (sold to a group of investors).

Parts are readily available for current generation Johnson outboards,
older engines can be a parts problem, especially clutch dogs and
gearsets. It depends on the age of the engine. Note Mercury Marine
markets some repair parts for older Evinrude and Johnson. So does
Sierra.

The currrent Johnson 90 is a conventional two-stroke with a carburetor.
It smokes. It´s noisy. Its fuel economy is not so great compared to
state of the art outboards.

The Evinrude 90 ETEC is direct injected, requires no break-in, no
initial maintenance for its first 100 hours and it winterizes at the
touch of a button. It also gets about 30 percent better fuel economy.
Its warranty term runs one year longer.

As for Suzuki four strokes, in my experience they survive as well as
any outboard in sal****er. the real question is whether you want a DI
or four-stroke.
