Worse fuel economy, even worse reverse handling & lower top speed than
regular inboards, but good starting/accel thrust and generally shallow
draft. Can be somewhat noisy too with the water rushing through the
hull. I like'm though, I hope to own one soon. Classic lines &
construction, straightforward driveline & easy maintenance, & can be
quiet too at lower speeds with the below-water exhaust feature. I like
the V-8 rumble, so would probably opt for the factory through-hulls
given my 'druthers.
