I changed the lower unit oil on all of the outboards. I would hate to have them freeze. I needed to dump the Hydra Sport in to get warm. I ran out of time and did the lower unit and parked it. The engine oil only had a few hours on it. No big deal. I believe with the correct prop on it, I we will use it more this summer. 28 mph sucked, the new 43 is much better. Hard to believe no one ever complained about the lack of performance on that boat.
