Good reliable engines. Plenty of parts around if you ever need em'. As said above, they do like gas if you keep your foot in em'. My current one is a 94 200 Venom on a 89' Stratos 201 Pro, it pushes my big heavy boat to 60 mph., plenty fast enough for me. Do a compression and leakdown test if those are good I would say go for it. Black, White, Blue, or Gray the color doesn't matter, there are good and bad engines of every brand!
