Were it me, I would get a 70" Water Walker Cypress series.

Call them and talk to Andrew, I'm pretty sure he will confirm that size. And take your order. :)

I've run both the 70in & 68in powershift with cypress blades on 2 different h2ad boats & trust me they both performed well.. I'm running the 68in now & i like it a smidge better for the snap..on this boat anyhow!

I ran an h2ad on a 12' Hamant for a few years. Mine had a 68" Sensenich 2 blade h on it and ran it the same places I run my current 6 cyl. boat.

Keep it light and drive it right and it'll surprise you where you can go with it.

Only problem I had with mine was moisture in the mag. Almost seemed like it created it own moisture sometimes and I'd have to take time to dry it out downriver. I've been around other H motors that didn't seem to have that problem though.

yep just like rick said these things seem to have moisture & ground problems in the mag..my 1st h2ad didn't have those problems but this 1 has cpl times..another thing thats very important is to make sure to keep good clean oil in it!! they tend to have cam & lifter problems.. I've had to replace lifters on both motors..bout every 3 -4 oil changes i inspect all the lifters..if i find any with pitting or galling on the face i replace them..either use camguard in your oil or you can buy the victory Phillips aviation oil with the lycoming cam additive already in it which is what i run

I've been running a 72" Wisper tip Narrow blade. It's but pushes good. The reason for the long prop is I had aspirations to supercharging this motor and never got around to it. Still did purty durn good. M

She's recently had her last run as the oil pressure won't rise above about 10 psi. Likely due to the cam and lifter problem.

I did have a mag problem one time, just need to try and keep it covered when stored.

I've run the dog mess out of that motor for about 10 years, only that one mag problem and 2 times burned a valve from running to hard on pump gas. Other than that, it's been a work horse.

I ran 0320h2ad for 2 or 3 years on a 10' home made alum hull.. it was my first airboat. it came with a 'cut down' power plus 2 blade. it had top end for days but suffered on low end grunt. [blades were wide]
I switched to a 68'' 2 blade cypress series prop and the boat was snappy, turned ALOT better in deep water, and ran the ground a lot easier. never had mag condensation problems with it, probly should of never sold it, but made a good deal on a 15' car motor boat.
