I have a 1997 Yamaha PRO V 200 lower, I was told by the marine place that its the larger lower and will also fit the 3.1 blocks as well. The motor lost two cylinders and I bought the boat to re power with a mercury I have. I have the complete motor minus the powerhead and carbs. The trim still works, the cowling is in good shape and the coils and ecm is there. I will sale it all or just the lower unit and located in Benton Arkansas
