I recently just purchased a 2002 Ranger 205vs and it’s only running about 56mph with a 225 Yamaha OX66 V-max.
Just replace the spark plugs, fuel filter, and water separator. Before I did all that it was only getting up to 51mph. Any idea what I can do to get the top speed up a little?? The boat comes out of the hole no problem. Wide open throttle is getting up to a little under 6,000 rpm’s. I feel like the boat should run in the mid 60’s from what I’ve been researching. Boat is not loaded down at all. Light tackle, half a tank of fuel. It’s got a 3 blade prop I’ll check tomorrow to see exactly which one it is. The boat does not have a jack plate I know that would probably help out some. Any advice would be greatly appreciated!!
