1. How do you change the impeller on an RXP... Is there a thread besides the one which shows it on a yamaha. That one shows that you need to take the rideplate off... Surely you don't need to do that on an RXP do you?
2. Is there a difference performance wise between the riva race opas block offs and just the regular opas removal. I don't race closed course or anything so just wondering about spending $100 vs. $300.
Wanting to put my impeller in this weekend and my pump wedge. I'm sure I'll have more questions with the wedge as I don't even know what the pump looks like yet.
This do it yourself stuff is quite addicting.

you need a removal tool to get the impeller out of the pump. Not to mention a bench vise and a 3 foot breaker bar.(i used a 3ft section of galvanized plumming pipe from Lowe's over a big Craftsman allen wrench.)
this is the pump (left,aluminum) and the reverse/vts/venturi(right, black)

the pump comes from here:
No removal of rideplate required. Just disconnect steering, reverse bucket, OPAS, and VTS. Take out four bolts holding pump on (closest to hull) and viola!

Impeller tool goes in the spline end (top picture) and allen wrench goes in hole under the pump cone (seen above grey cone on left). Picture below is where the allen wrech goes when pump cone removed:

Do you guys add grease to the pump cone when putting it back on? If so how full do you get it?

On the install is there anything that needs to be sealed, loctited, antiseized, or anything like that? Thanks for the pics, I hope to do an impeller this weekend.
