Re: Dialing in new boat..

Great info Jason I find it interesting to note he reported he had the JX blades spinning at 5400 rpm then added more pitch to almost the 2 mark bringing them down to 4700 rpm. He ran those blades in a good pitch range but was just not getting the push he needed. Sounds based on your testing a ratio ...

Re: Dialing in new boat..

I think he has a 2.55 gear box so the ratios are close.

Certainly a 2.55 is a bit better than a 2.3 with your dyno data.

Re: Dialing in new boat..

It sort of makes for more questions. I prefer to run an extra blade on a gear drive boat rather than run a heavy pitched prop. That said every series of blade is different and some may work with heavy pitch better. That engine is what Blackwater runs and it should be a beast. Jason runs a tour boat ...

Re: Dialing in new boat..

I'm kind of puzzled with this choice of blade on a 18ft X 8ft powered by a 540 MAS Was the JX selection something you wanted or did someone from Sensenich feel they were your best option ? When I first heard of the proto type blades being tested was around the time I was buying my S blades and we we...

Re: Dialing in new boat..

My bet is it pushes close to the same or slightly less. It is my belief that the JX was created to give a better push than the R series but require less torque at the lower range than the S series blades. When you have a big displacement engine like a MAS or a Branch with the correct ratio drive the...

Use that Branch Brew oil blend or Amsoil Z-Rod and protect your thrust!

If your budget will not allow you to get a gear drive then an aircraft engine is way out of your reach. The cheapest engine to work up is a small block Chevy.

Re: First airboat, how to check thrust play??

It is more of an issue in the Caddy than sbc If you push and pull on the prop hub and the crank is moving in and out that is your thrust clearance. If it just moves ever so slightly you will be fine it is when you get a sizable movement that your gonna experience a issue. The process to get a true m...

Re: Rigging, how far forward can I go?

I don't know that there is a limit or restriction, especially if you need to move weight forward to improve your ride quality. Your steering will be effected most likely. To mitigate some of this you could utilize a longer prop adapter. Most guys run a 2 inch but I have seen 6 and 8 inch adapters th...

Re: Metal filings in oil and two pins came out drain plug on Briggs 35 help

I looked at some internals and the Vanguard has 2 roll pins associated with the smaller gear so the governor assembly is highly suspect.

Re: Metal filings in oil and two pins came out drain plug on Briggs 35 help

Metal in the oil and large pieces of components is a sign of a catastrophic failure. Your boat had a recent modification (poly) and you noted a lesser ability to run dry ground. I am thinking maybe this caused you to push your engine harder and as such a internal catastrophic fail. Lets hope it is s...

Re: Metal filings in oil and two pins came out drain plug on Briggs 35 help

That sounds like some very BAD news! Maybe the oil pump gear?

Well if you decide to go all out these guys have a bunch of trick components to take a Vangard to the extreme including a supercharger in the very near future.

Keep us posted and take pics

Re: Cadillac 472 Water Temp Sensor Location

I suggest the location you refer to as the "right head location."

Are you using a mechanical or electrical gauge?

I suggest ARP thread sealant it uses a liquid paste Teflon and works great.

Re: Dialing in new boat..

It is hard to push a big boat dry. While I have not used the new JX it would be an interesting field observation to put a 4 S-blade set up on your boat and test it's response. The wider S-blade design may push better. Your one of the new JX users so we are watching your progress. You have great dyno...

Re: Trailer supplier in Central Florida

Yea our mount is forward of the cage and exterior so no chance. I have seen a few guys use them on the boading side of the cage exterior and they just raise it up and lower when getting in and out. Ones I have seen work well just need the correct size shaft for the device.
