I ordered the little L70AE Yanmar air cooled diesel tonight, along with a tapered shaft to 1" keyed shaft adapter. The K181 will be coming out and the diesel going in very soon. Need to get my yards cut early in the week so I have enough down time to get it in and sorted out before they need mowed again. The Yanmar is set up for 24vdc for starter and a pair of intake grid heaters for very cold weather starts. I am in debate mode what to do with it. Most depends on if the extended air filter mount due to the intake heaters helps or hurts hood clearance. I can get a 12vdc starter for $65 for it. There is a place under the seat pan to place a second battery and I can run cables forward thru holes in the bulkheads with gromets to protect the cables. Then tap 12vdc off one battery for the lights. I know the yanmars will start in the local weather without any preheat, so chances are, I will convert to 12vdc. The engine lacks charging, I can add that, but I rarely use the lights on the horse and I planned to put LED bulbs in them anyways. So a simple float charger will work for now to keep the battery up. Pics coming once I start the conversion. Mike
