A Review of the History and Technology in 2.5L Hydroplane Racing Engines
Modern marine engines are as varied as their road- and track-going counterparts. Whether they’re powering working habor tugs, ocean-crossing container ships, leisure and fishing boats or hardcore racing boats, marine engine builders are dedicated to improving their performance and reliability through innovation. 2.5L engines have been used in both midget racing and hydroplane applications for
Head and Block Resurfacing Equipment
Regardless of what type of engine work you do in your shop (stock, performance, diesel, marine or anything that comes in the door), you need the ability to surface heads and blocks. Deck surfaces on high mileage heads and blocks are often corroded, pitted, scratched and/or out-of-flat – especially if the engine blew a head gasket or overheated.
Honda Marine and H2O Sports Manufacturing Announce New Agreement
Honda Marine, a division of American Honda Motor Co., Inc., and H2O Sports Manufacturing, LLC announced a new agreement to revive the Trophy brand boat to be powered exclusively by Honda Marine engines. Honda Marine is a marketer of a complete range of outboard marine 4-stroke engines.
How Today’s Wake Surfing Craze Can Be Killing Marine Engines
According to some experts, wake surfing has become one of America’s hottest sports. For those of you who are actively involved in building engines for pavement or off-road racing, marine motors may seem to be either an obstacle or an opportunity – and you would be right in both cases.
When Oil and Water Mix – The Marine Engine Market
For those unfamiliar with marine engines, there is a common misconception that these are highly unique devices. This simply isn’t the case. If you can rebuild an automobile engine, you can rebuild a marine engine. If you can build a solid, reliable drag or circle track engine, you can build, or rebuild, a marine performance engine. The key to success is understanding the subtle differences and being able to recognize the pitfalls.
The Origin of ‘Coal Rolling’ and the Story of Diesel’s Evolution
The diesel engine replaced steam engines that were being used in locomotives and ships. The diesel engine also became widely known for its use in submarines, stationary power plants and trucks. In the last 100 years, the diesel engine is credited as the modern day workhorse, as there is an abundance of high torque at low RPM.
Scratching the Surface: Coatings and Treatments for Engine Components
When it comes to preserving performance parts, it’s the ‘Icing on the Cake’ Various kinds of coatings and surface treatments can be applied to engine parts like icing on the cake to improve durability, enhance scuff resistance and lubrication, control heat, boost thermal efficiency and reduce friction. No single coating or surface treatment can
Crack Detection and Correction
First off, let’s get one thing perfectly clear – there’s no such thing as “flawless.” Like those shocking tabloid photos of that Hollywood actress who gets blindsided beside a bistro, even the most conscientious engine builder sometimes has to deal with surprising surface imperfections. And just as she has paparazzi to expose the damage and
Understanding and Profiting From the Caterpillar C7
I believe society naturally directs the outcome of its environment: if someone manages a quality independent automotive repair shop, they will always be looking for ways to increase their education and specialty tools as technology changes. In order to take care of their customers when the warranty runs out and they no longer visit the
Diesel Engines: Dino Fuel or Bio Fuel?
Though they lately seem to be going the other way, with rising fuel prices, consumers are constantly looking for inventive ways to cut fuel costs and consumption. That’s the American spirit: we love to look for ways to beat the system. There is nothing wrong with this attitude, because this is where inventive minds
Mast Motorsports Expands Manufacturing Capacity with New Powertrain Division
Mast is gearing up its capacity and capabilities at the company’s headquarters to provide state-of-the-art engineering, design, testing, and manufacturing of powertrain products for multiple markets, including automotive, marine, motorcycle and industrial. The addition of Mast Powertrain coincides with the company’s rapid expansion. Groundbreaking recently took place on a new 10,000 square foot facility that
Valves, Guides and Seat Materials and Selection
Ginsu knives became a household name by blasting infomercials showing how their superior steel blades could cut through a shoe and then slice a tomato paper-thin. The blades would bend and flex and never lose their sharpness. Millions of homeowners bought the knives; however, you would be hard-pressed to find an executive chef who used
Selecting Valve Seats for Gas and Diesel Engines
Hard working diesel engines, performance engines, and engines that run on dry fuels such as propane or natural gas produce a lot of heat in the combustion chamber and often require valve seats that are harder and more heat-resistant. Stellite, chromium, cobalt, tungsten and nickel alloy valve seats are commonly used for such high heat
Valve and Guide Material, Selection Update
Today’s engines are being designed with more valves per cylinder with smaller valves to reduce valve train weight and increase intake volume. Cylinder heads typically require valve guide and seat work to restore compression and oil control if you are rebuilding the heads. For the valve to seat properly and to gain the most power
Performance Marine – Is It the Last Engine Frontier?
It is said to be one of the last great open frontiers. Many experts say that it’s just about the last place on Earth where there are no rules to confine speed or size. It’s a place that has lured men with adventure and danger for centuries and now may be calling you, the engine
Understanding The Mysteries Built Into The Ford Power Stroke Engine
After servicing and answering questions about these engines for several years, it finally occurred to me that the owners of these engines didn’t understand how they work – and, frankly, neither did many repair techs. I remember when Ford introduced the Navistar engine in the middle of 1994. The rumor on the block was that
Camshaft Ticking Noises on some 3.0L 4V Ford Duratec Engines
Some 2005-2007 Five Hundred, Freestyle, Montego, and 2006-2007 Fusion, Milan, 2006 Zephyr, 2006-2008 Escape and Mariner vehicles built 1/17/2006 thru 5/31/2007, equipped with the Ford 3.0L 4V Duratec engine with exhaust camshaft driven water pumps may exhibit a ticking noise from the left bank cylinder head with the engine at normal operating temperature. Engine Builders/Installers

Marine Motors: Challenges & Opportunities
On the popular British automotive television program “Top Gear,” the hosts were interested in discovering how hard it could possibly be to build a vehicle that was capable of both being driven on the road and sailed in water. Various types of such vehicles have been dreamed about, designed and even occasionally produced over the
The Ups And Downs Of Valves
It’s always good to take a fresh look at some of the many engine components we work with. Rather than being lulled into complacency, the idea is to see what’s new, what trends are in play and to get a current reading from others on the inside. In other words, it’s good to keep it
