    The 215 RXP is shorter and lighter and has VTS. Those 3 things contribute to the ability of the RXP to turn a larger impeller (more Pitch) and ultimately go faster than a 215 RXT.

    +1, it will take more power on the RXT to pull the same prop.

    You shouldn't have dropped r's going with a shorter prop. What were the variables involved before and after the swap?

    You need to adjust the pitch a little. Make it basically an 11/18.5 pitch and you should
    pick up couple hundred rpms and 2 mph or so.
    I've found the 155 mm props from solas to be a little "bigger" than they really should be.
    BTW, a 185 hp sc engine stock, barely pulls the 12/20 to 7200 rpms too.

    We also don't know your temps- water & air, humidity, elevation, rider weight, etc
    These all contribute to how many rpms your engine will get.
