Re: Moving to Tampa soon!

Polk has an airboat ordinance and they are not allowed on the Winter Haven chain unless it’s a clean up event there are areas in Polk they turn a “blind eye” on but most of the conjested lakes you’re askin for problems with ole’ Shady Grady so be sure you check the areas you plan on running..

Re: Caddy 500, 4bbl carb or Holley Sniper?

SWAMPHUNTER45 will probably chime in and tell you the low down on efi and a caddy. If not PM him. Or call Buddy Branch and ask him as no one would know better than Mr. Branch. His number can be found with little Search on here.

Re: Oil cooler hose

Ones I am running now are crimped and a solid piece. Shown in picture. On last boat I made my own with screw together AN fittings and SS braided hose. With quality fittings and quality braided hose I would trust the screw together and crimped to the same PSI(300+) which would exceed the PSI the oil ...

Re: Oil cooler hose

Diamondback sells SS braided ones for oil coolers I run them never an issue. Any manufacturer probably sells them . You Might be able to get the fittings and braided hose a lot cheaper and build them yourself online or local hot rod shop, or Napa. Mine have brass fittings on them not aluminum.

Re: Just bought airboat, getting ready to start after a couple years of storage.

I’ve used 3M auto body panel adhesive to secure nuts on all-thread. The adhesive I use is considered permanent. Not saying this was what the previous owner did. hell I’ve seen acorn head bolts before but they were pretty pricey they came in SS and chrome. If you have not removed one yet it could be ...

Re: Fuel pressure drop at 180

The newer PCM/Levitator engines go into “limp” mode to protect them when they reach 220* as a protective measure. The engine will be limited to 2000-2200 RPM once the engine drops below 1200 RPM it will allow you return to full power. Have you tried a new temp sensor? Might be faulted. Strange you a...

Re: Scallop question

Re: New prop help

I’m running a PCM/Levitator 6.0 published numbers state 375hp@5xxx and 366ft/lbs TQ, personally think they are over inflated for my model year.

Re: New prop help

That K series produces max thrust @ 2800. You are leaving a good 500-550 RPM on the table. However if your engine is not capable of higher rpm then set it as closely as you can to the cam specs max Rpm. I twist a 81” 3 blade K series @ 5500ish WOT w/ch3 2:1, cruise at 3200-3500 (23-28)mph give or ta...

Re: Reduction options

Max RPM for the EX is 2500 Rpm. Multiplied by your reduction 2.12 is 5300rpm which would be you MAX RPM seems like you are leaving 400 + RPM on the table. You can definitely feel the difference in just 200+ RPM. I would suggest you repitch the prop to a static rpm of 5000 RPM then water test it and ...

You can do it that way but disconnect batteries don’t trust the perko or kill switch! You could use a flashlight as well look up Inside best you can or better yet an inspection camera. The belts don’t have any give so a ping pong ball size nest will break the belts

If I was you I would Immediately get rid of the acorn nuts. They are not the proper hardware for that belt drive and they will destroy your prop. Century’s website can tell you the proper bolts you need to replace them with. Based on pictures you have mud wasps. They are prone to building nests on t...
