Maybe You alreday note one improvement made to my auxiliary engine. I note, that when the engine was in "up" position, it was quite hard for mounting and transom when going on waves. So I put a rope at the leg of the engine and and reeled it through the block mounted above on the A-frame and then to the snatch on the side of the A-frame. That makes riding on the waves with engine "up" stressless and it is much much easier to hoist the engine into "up" position.
