I was reading this thread on break today and thought I would ask Glen Wooldridge. Here are his thoughts.........

alanmikkelsen- You are correct about rocks between the exhaust tube and housing.

The 4-blade works great with the 90/65. It doesn't lose any top end speed even with less RPM's which are sometimes confused with less speed. The 4-blade stainless is also better at getting a load up on plane. It stands up much better to rocks and wear.

As alreay stated, shim to .015 with a new liner if yours is badly groved.

Glen
