An outboard thrust washer, with a single shaft at the end, provides engine outboard location, providing a smooth and steady rotation for the propeller shaft. The wash is directly connected to, or held in place by, the case, providing a loose screw fixing method.


More and more electric or hybrid cars are hitting the road, but what about boat engines? Will we soon enjoy the silent hum of a battery-powered outboard? Many of our fishing boats already have electric trolling motors, and plenty of anglers also use electrics on car-toppers, canoes, or kayaks. But when you go beyond three or four horsepower, battery demands become overwhelming. And yes, electric outboards do go well beyond three or four horses.

While it is hard for many Americans to grasp, Europe is leading the way to the future, and boating is just one small manifestation of what is going on. Despite the many nationalities, cultures, economic systems and languages, Europeans are taking global warming seriously. Local governments are often taking the lead, passing legislation to reduce, restrict, and eliminate emissions from ICE (internal combustion engines), and curtail the use of oil-based products wherever possible. European manufacturers of ICE engines such as Volvo Penta have announced plans to be all electric within the next ten years, and Volvo cars will be all electric by 2030. (Source: boattest.com)


Well over 100 years later, the engines themselves may well be ready for prime time. But until we come up with a power-pack that’s radically better than even the best of the lithium-ions we have today — and which carry reasonable price-tags as well — using an outboard for primary propulsion on a boat will mean a radical loss of range and an epic jump in price. The bottom line: Unless you’re wealthy, at least for the time being, running an all-electric boat is not a realistic option.

If going all-electric is beyond our current ability, are there other options? Yes, Lehr has proven that propane is a viable option, with its line of 2.5 to 25 HP outboards. And an outfit called BlueGas Marine has modified a pair of 275 HP Mercury Verados to run on natural gas and claims zero performance penalties. But truth be told, despite all the hype over alternative power sources, if you plan to run a powerboat with anything over a handful of horsepower, at least for the foreseeable future it’ll be powered by a gasoline outboard.
