I replaced the prop on my 1993 90hp Mariner with the cross referenced replacement made by Mercury Quick Silver Black Diamond. They are both 13.75" by 15 pitch. The replacement has the hub kit conversion while the other had a pressed in exact hub with the 15 splines. The new prop grabs all types of air upon take off and requires a very gentle acceleration to make it avoid spinning and allowing it to grab water and reach full speed. The older prop had always worked great, it was just old and a little ragged. I put the old one back on but want to replace it eventually. I understand Michigan Wheel and Prop makes one with the pressed in hub and am tempted to try this. Any ideas on what the problem is?
