After dealing with the issue of tender engines (electric vs. traditional), today we are going to discover a novelty that comes from Germany, to be precise from Berlin, where the headquarters of the Arens engineering company that invented the portable inboard engine, RVI Sail 15 of Arens Motors.
What is it that ruins engines?
The engineering team arrived at the idea of making a two-stroke inboard engine with an S drive transmission that could be easily disassembled and transported. In this way during winter or when the boat is in the water for a long time, it can be removed from the boat so that it is not left in contact with salt water and the surrounding environment. From this idea came RVI Sail 15, designed for boats up to about 10 meters, which takes up the space of a suitcase. The power output of this detachable inboard is 15 horsepower.
A modern two-stroke
Modern two-stroke technology, in which oil is not injected directly into the fuel as before, but is automatically injected in small amounts at the points to be lubricated. This eliminates the need to check the oil pan, oil pump, filter and oil pressure, which also causes extra weight. Two-stroke direct injection technology effectively eliminates the control of sump, pump, filter and oil pressure. The ease of transport is also given by the weight, 37 kg, which allows two people to move it easily
