Should run OK. Are you keeping the factory ECM or going with a carb? PM ls1airboat on here if you keep the injection - he knows the in's and out's of these engines from learning on his 5.3.

Yeah, it should run some dry. What kind of hull? what thickness is the poly?

Yes it actually does, because I know matt would gladly drive a reasonable distance to help him set up his engine right, it wont work at all if you don't know what your doing :violent1:

Huge question: Is your LS an aluminum block motor? If it is, it probably won't take the thrust load of a prop.

Just an FYI to avoid any confusion...I went ahead & merged the other identical thread in Airboat Talk with this one.

No more than 3,000. If you keep the boat light and set it up right, it should be able to do a little bit of dry ground.

It should run dry fairly well if set up right. I have a 12x8 and it will run some dry.
