Covid-19 was a convenient excuse, they wouldnt have lasted much longer even without the pandemic.
I have 2 four strokes. One is a Mercury and the other a Tohatsu. The Tohatsu is a 3.5 and I think the Mercury is a 4. Both run our dingheys great. But my fav motor I use for just around the harbor is a cheap electric motor I bought off Walmart.com. Sooooo easy and the kids can use it.
