hi, i am new at building airboats, i am on my second build the first one worked good but this one should be better. i have pics. it is 38" long 20" wide with a 25cc homelite, oversized carb,an a 16x10 3 blade prop .it is wood from a interior door lol but works great ,plus i am a wood worker so works good for me ,going green lol it is still under consrtuction. i built this with no plans just looking at pics and reading , hope i am doing good .

looking good . props probably going to be to big for that motor. also the props on backwards lol. watch the cage and prop may hit under load . the master airscrew props flex a bit under load

well on your way

thanks ptr34 and greygoose81. i was afraid the cage might be to tight, will work on that, thanks for the advice . so on the prop which edge is the leading edge then? the motor turns  turns counter clock wise . thanks!

The lettering should face the engine.

l_curly

so the round edge is the leading edge of a pusher prop?

crispyspa

The round edge is leading edge on all props.

Yes i agree with ptr34 that prop will most likely be to big i have a 25cc husqvarna on my boat and im only useing a 14x6 2 blade and it works like a charm

Mr Cajun Gator

go with the 14 x 6 2-blade prop. I would move the engine forward about a 1-1/2" with a little more support on the engine stand.
