I could b wrong but that doesn't look like a 0320 h2ad to me..& the I'd tag doesn't say h2ad either..I own 1 & my manual says 100ll not 87.. Complete different motor if it's not valve train etc is all different..Nice looking boat tho
 
You are correct, maybe a good thing you pointed that out. My bad. :blackeye:

I intended to put a qualifier in there that his engine was similar, but it may help anyway.

I was running late and omitted putting that in there. :oops: Thanks for the correction. :salute:
 
Thank u so much for those links ! My one worker is a pilot and he said all the 0320s he flys have been stamped
100LL ,,, he is of the impression that it is a higher hp engine that has the compression lowered for 80/87
That would be nice , as we have several thousand gallons of 112 sunoco at the shop ( they sponsor our cars )
So if it could be that simple as new slugs to up the compression , wiseco makes what ever we draw up for pistons pretty cheap ! Im getting ahead of myself a bit
... first i better learn to float and steer at the same time ! Lol
 
My answer to the original question ,,, Ok , from the little i now know , 0320 boat , really lite , warp drive 6 blade , 2700rpm on the trailer , pretty fast in the water , surprisingly fast in the water , GPS said 49 mph ,, that was up stream , down stream would have been faster , but my phone died so idk for sure ,,, anyways , i am going to need a ton more power for my conditions to run dry , like 3Xs the power or more , we had to tow the boat with a tractor to get started in the dry , which was flat & wet green grass ! Then the wet brown dirt , stopped me dead in my tracks , forget hills , not a snow balls chance in hell , the tractor had trouble pulling the boat up packed wet dirt hill , 4x4 tractor , i thoght it was going to pull the trailer ring out of the hull ! Now the chevy powered boat that was much larger , went ok here on dry , that was a dirt modified dart block , Brodix head near 700hp , 2.6:1 i think , no clue what prop , but on dry here , it was ok but not over powered at all , it was quick not fast on water , i dont know if it would get up my hill , but the customer seemed pleased when it pushed the truck and trailer up the ramp in park , ramp was prob slime !! But he smiled ! Based on how much pull i had to add with the tractor , there is NO way i would believe that a 4 cyl boat will run dry here, in the water , great , in tall grass no problem ,, on wet brown dirt and green wet mowed grass , here at my farm , NO , not a chance , not even close , Fun as hell in the water tho , and much quieter then i figured it would be , 60" prop , steel coat bottom , it hates green grass , i have had ancors that dont grab as well ! Lol. , this is my feed back , for what its worth ! Im no expert in airboats , but i am with tractors and engines , we are all shocked at how hard it was to pull on flat ground with a tractor , that is my guage ! Im open to reccomendations , and i get that how fast it is in the water is prob making it less good dry , perhaps 300hp in this 11' hull with the rite prop may start to work , but like this my dog could not even ride with me ! This was all one 180lb person , good luck with your boat ,,, whatever u decide to get , W
 
Whats it got on the bottom? You might have said but I don't feel like rereading. If poly than you have some sticky stuff. If bare glass that can be a problem.A coat of steel flex 2000 will make it seem like you added another engine. Lot cheaper than a engine package.
 
So does that mean if he took the Steel Flex off it . . . it be like it had no engine at all ? ... :scratch:
 
its steel flex and its like glue for my conditions ! 4x4 tractor that would drag a 2wd pick up in park had trouble dragging the boat while i was turning 2700 rpm ! add thin water and it launched but the brown wet dirt literally stopped me from like 15mph ... on flat , i got launched outta my seat ! lol !
i watched tons of videos ,and my conditions are different ! but doable with the correct boat ! W This shit is fun
 
get a spray bottle of tire blacker from auto parts store
get stuck spray a lil in front of boat........unstuck and go :cheers:

Sorry Deno, If you have poly it's going to be slick, so there is no reason to go any farther. If the hull has nothing it will get stuck faster than if you have steel flex 2000. Regular steel flex is not as slick as 2000. I was saying that for a couple hundred dollars the bottom will be slicker and might help.
