Re: Airboat power measuement

I use a hyd. scale that goes to 1K lbs. You can do it on the water or on the trailer, one thing you must subtract the lbs. it takes to move the boat with out the eng. running from the total amount you show on your scale or gauge. This is the way that I do it, and I use a hyd. scale. Zoom.

Re: Still Learning Lessons

Digginfool, you live in Miami for nuts, and bolts for your boat go to "Avico" in Miami Springs, they sell aircraft hardware it can't be beat. You can get bolt lengths in 1/8" increments, they are supper strong with out being brittle. Zoom

Re: Type of rivet for poly

Use AN426- A-6 about #9 in length, and use aircraft 100deg. If you don't have yourself a "stop sink" buy yourself one it will make the job a lot easer. I did the same job on one of my boats about a year ago ( the rivets must be flush), good luck!! Zoom

I've been skimming your post and if I understand what your saying you are having some fuel starving problems due to pick-up tube size. I have been running a EFI engine since 1999 and have had no fuel issues. I merely copied what the manufactures used, I figured that they spent millions in R&D, a...

Re: Warp???

I have run a six blade turbo prop on my boat for years, the only thing can say is that it changed the pitch level, or noise of the prop, which was what I was looking for. I can't say that it produce more thrust than my straight blade set up. I have now changed again, I'm now going to run a straight ...

Re: Warp drive turbo prop question

I ran about 7 yrs. with a 5 blade warp 80 in, it suited me OK, but I didn't like the noise, so I went to a 6 blade turbo it seems to be quieter and a lower pitch noise. Now for push, to me that subjective, if you run long enough you can stick any of them. The only way to know which pushes more is to...

There is no substitute I for larger diameter when looking for more thrust with given horsepower.

Joe, the gears that I use in my gear boxes are planetary. The reason for this design, planetary gears have more than one point of contact. The big box has eight the smaller box has five.
