Joined: May 2005 Posts: 8,878 | I know of nothing other than the original pump, or an older 216 pump used with an adapter plate.
Grigg | | | | | Joined: Jan 2005 Posts: 1,602 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 1,602 | Isn't the limitation on the water pump is the size of the water hose outlets? It seems to me no matter what water pump you have those 5/8"(?) hoseoutlets are going to be all the flow you ever get.

I don't see them as being restrictive.
Grigg | | | | | Joined: Jan 2005 Posts: 1,602 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 1,602 | You are correct. I was thinking of the heater hose outlets that come off the water pump. The restriction might be the smallest part where the propeller is fit against the block/head in a 216 and the adapter plate openning.
