So if you're a freshwater fisho and don't want the fish-spooking problems of a trolling anchor under your boat, you either fit a carbie two-stroke and an electric trolling engine, or a fuel-injected four-stroke (the latter also has the advantage of being able to automatically adjust its air/fuel ratio according to barometric pressure and won't run rich on high altitude dams such as Eucumbene). But that doesn't mean they suit all applications.įor example, because of their higher compression ratios and greater mechanical complication, carburetted four-strokes won't troll as slowly as comparable two-strokes. Provided they're fitted to the right type of hull, I have a preference for four-strokes in this power range. So much so, that some Trailer Boat readers face a dilemma - whether to choose a two or four-stroke. There is an extensive choice of engines in this range, with more and more four-strokes being added to the list. They suit planing hulls from 4.5-5.5m - those capable of being towed by four-cylinder cars. A boat can be highly maneuverable with a smaller, lighter-weight motor, and bigger doesn't always mean better, especially when weight is a concern. A motor that is too large can cause the bow of your boat to ride too high in the water, or even create excessive drag when running at slow speeds. A motor that is too small can be overworked based on the load.īenefits of buying from Defender Industriesĭefender has been in the outboard motor and marine parts industry for decades.

In 1957, two Mercury 90 HP motors set endurance records on a test lake, running 50,000 miles at an average speed of over 30 MPH continuously (stopping only to swap drivers and routine maintenance), and were still well within factory tolerances for wear and performance. This is a record that has never been beaten.
Over the decades, Mercury has built on its reputation as a leading outboard engine manufacturer and still holds records to prove its dependability, fuel economy, and performance.
