I am changing engines on my rib and Have a question. My last engine (yamaha 200 2 stroke) was a premix set-up which i actually found convenient. I have quite large fuel tanks on the boat and it was simple to put in 50 litres of fuel and 1 litre of oil. I was always confident that if the engine got petrol it also got oil. This latest engine (yamaha 175 2 stroke) is auto-lube so I would have to install an oil tank and route cables and a pipeline between the 2. I have been told that it is an easy option to disconnect the auto-lube system and continue as I was. What do the masses think?
