Diesel Engines and a Cleaner Environment

Power & Propulsion

If you pay any attention to the topic of boat engines, you’ve probably heard the term “common-rail diesel” bandied about and perhaps wondered what it means. In fact, this technology is in no way restricted to the marine venue; it’s also common in both stationary and vehicular powerplants, mainly because it helps diesels meet new, stricter emission standards.

A Guide To Proper Seawater Plumbing

Plumbing for seawater circuits is critical. Centrifugal air-conditioning pumps must be below the waterline to prime, and seawater hoses must rise continuously uphill from the through-hull fitting to the sea strainer and to the pump, and then continue uphill with a single high spot at the air conditioner.

How To Add an Air Conditioner to Your Boat

How to Install an Air Conditioner on Your Boat

Boatbuilders want simpler installations, so today many air-conditioning systems now contain all electronics within a single remote-mounted electrical box. This allows flexible placement of air-conditioner units and simpler electrical connections—both are huge benefits for do-it-yourself installations.

Engine-Mount Maintenance

Properly maintained motor mounts result in more than just a vibration-free ride.

Regardless of what fuel prices are doing (wise not to think about it too much), it’s best to get as much as you can from every tank of fuel. Smart boaters are looking closely at their engines and tuning them for maximum efficiency. But based on my experience, it’s a safe bet that even many experienced boaters are overlooking one critical area...

How to exercise an unused engine

Sometimes I don’t have the time to actually take my boat out for two or three weeks at a time, but I do have time to run her Cummins diesels now and again. How often, how long, and at what rpm should I do this?

Eliminate Osmotic Blisters In Your Hull

Adore A Vacuum?

Don’t Laugh. This One From Hotvac Is Designed To Eliminate Those Ugly Osmotic Blisters In Your Hull.

Hull blistering is a fairly common sight in boatyards and, as its name implies, consists of small, unsightly bumps on the boat’s hull below the waterline. Blistering can adversely affect a boat’s fuel efficiency, speed, strength, aesthetics, insurability, and in some cases, safety...

Recreating A Boat's Helm

Tired of those old electronics? Why not give your boat a whole new helm?

Here’s how one boater recreated his boat's helm. With mounting frustration, Pasquale Didonato eased his 48-foot Sea Ray Sedan Bridge out of the C&D canal toward the northern end of the Chesapeake Bay. It was well after dark, and a raster-scan radar screen gave his countenance a spooky glow as he leaned to the right in a half-crouch to check his lineup on an upcoming set of buoys...

What You Need To Know About Propeller Options

The right set of propellers can smooth the ride and increase efficiency.

Cruising in your boat is a pleasant experience. If you could make it more enjoyable while spending less money than you might expect—and throw in some fuel savings while you’re at it—it would be a no-brainer, right? Then you should consider upgrading your propellers.

Filling Batteries With Liquor Bottles

Garmin’s Tip of the Month, April 2012

Refilling my batteries tends to be a tough job because they are hard to get at. What I use to make the job easier is an empty 1.75-liter plastic liquor bottle. The plastic insert in the neck makes pouring the water into the battery cavities both easy and accurate. And to refill the bottle I simply remove the plastic insert with a screwdriver, pour in the water, and then snap the insert back on. The best part, though, is that I get to enjoy the liquor in the bottle as I empty it.

Handling heavy engine parts

When replacing heavy engine parts such as manifolds, thread two bolts with the heads cut off into the outside bolt holes to line up the gasket and manifold with the exhaust ports. Start the new bolts in the empty holes, and when you have installed several of them hand-tight, remove the studs, thread in the last bolts, and tighten everything. This eliminates the difficult job of lining up the gasket and the manifold with the exhaust ports. It also makes manhandling heavy parts a one-person job.

Keeping your boat smelling fresh through the winter

Garmin’s Tip of the Month, Feb 2012

When winterizing your freshwater system, save the antifreeze jugs, cut off the top half and dry them out. Add about one pound of baking soda to each and place them around the inside of your boat for the winter. They will absorb odors, and when you uncover your boat in the spring, she won’t have that musty smell. Be sure to place jugs in your refrigerator, ice maker, lockers, and anywhere else odors typically accumulate.
