What is Corsa Captains Call exhaust?

With CORSA’s Captains Call™ Diverter Systems you can enjoy the open water sound and performance of an open thru-hull exhaust system and still be a quiet neighbor in the marina. Exhaust flow can be routed through the transom for open water running or through the prop with the simple flip of a helm-mounted switch.

How does through hull exhaust work?

THRU HULL. The most cost effective exhaust option is a full time thru-hull system. This system allows the exhaust to exit full time through the transom or side hull with out any control over the exhaust flow or sound.

What does a water shutter do?

Many exhaust installations include shutters to prevent water from traveling back up the exhaust and into manifold.

What is the advantage of through hull exhaust?

The motor will have to come out no matter which way you go. Thru-hull exhausts are used for performance/sound/looks reasons. They look cool and sound neat. You may pick up a little hp with a stock motor.

How long do marine exhaust manifolds last?

Most experts suggest that a manifold will have a life expectancy of six to eight years. However, heavy use in saltwater can see this drop to as low as three years, while lightly used freshwater boats can get up to 20 years out of a manifold.

What are flappers on a boat?

If you back a boat on a trailer too fast into the water this could also occur. A flapper (or baffle) keeps this surge of water from pushing into the exhaust. If your boat has curved downward exhaust tips, they will also prevent water from surging into the engine.

How do you measure a hull exhaust?

Measurement X – Distance measured from the top of the drive (gimbal) housing to the horizontal center line of the exhaust hole. Measurement Y – Distance measured from the vertical center line of the drive (gimbal) housing to the vertical center line of the exhaust hole.

How do exhaust manifolds work on a boat?

It collects the extremely hot exhaust gasses directly from the engine into an inner “pipe” or long chamber which is usually cooled by raw water running through an outer casing. From here the hot exhaust gases and water are fed to the riser where the gases and water combine to continue their trip overboard.

Why the water is not coming out from the exhaust pipe?

A bad piston or worn piston rings will generally not cause water out of the tailpipe unless the head gaskets are also blown, or there is residual condensation in the exhaust system.

Why do boat engines spit water?

Use raw water from its surroundings to keep the engine cool, which flows in through the seacock, and is expelled through the exhaust. Are often quieter than dry exhaust engines, because the water absorbs the noise and heat, which is why many boaters prefer them.

How do you clean a marine exhaust manifold?

One popular method to help clean up an old, dirty exhaust manifold is using an acid bath. Acid bath – An acid bath should be able to remove many of the problems that are present in your marine exhaust manifold. This is also very simple because it is a passive cleaning method that you can take advantage of.

Should water coming out of outboard be hot?

Your water flow should appear steady in most outboards. You also want the water coming out to be warm, but not excessively hot.
