Should be fine if it turns . its normal for the housings and wear rings to be a little out of round and a quick run will sort it out. When we...
Same pump you looked at http://www.meanchicken.net/webmain/forum/viewtopic.php?f=69&t=8741
We need pictures ;)
The multi stage pumps are hi volume ,HI FLOW axel flow pumps, designed to lift, grip , and run with a grill half full of crap. Many guys agree the...
4.3 vortec would be perfect , but you should look for a flopro/hamilton/kodiac 2 or 3 stage jet unit. They are all the same thing and perfect for...
Stand up 550 ski gear shoud fit in a kayak, but then a small glass dingy would be more fun and cheaper ?

Best I can advise is to Forget the tunnel , Go for a deadrise of 8-12 degrease to keep the unit in the water and reduce slideing. Defenately use...
As the boat moves forward the tunnel will fill with air . Its very important to keep the flow of water to the unit clean. For low speed shallow...
The jetski units go well, but HATE junk in the grill. You can skim over the weed if its below the surface 150mm or so but youd want atleast a 7.5...
I think your tunnel will feed air to the unit, Not Good. The unit needs too be at the lowest point like this...
