alum pump shoe?
i found on forum this pic and dont know what is it for? i was talking with my guy how repairs me sea-doo and he said that in beginning if this tunnel is so small and if to make this slut bigger, it could take more water. like sea-doo made it specially to reduce speed...and lots of people can make powerfull engine but it will be hard to go fast with small tunnel....any ideas?

I think your guy is on glue????? The X boats have bigger tunnels and at high speed the pump will overstuff and buck you off. If you goal is top speed then stick with a rxp and mod it.

I would like to make the tunnel smaller to go faster on top end and help elliminate the overstuff. We gave up trying at 88mph, anything over that would require a smaller tunnel or different approch to relieve pump pressure.
I wish someone would make a aluminum pump show for the x boats

I think I remember JD-1 talking about fabricating an aluminum pump shoe a couple of years ago. He was developing so much power at MB3 or 4 that he ripped the plastic pump shoe out one of those years.
