Hi everybody, Im new to airboats and need some direction setting up a 2004 5.3
I’ve ran a lot of other boats up here,
But no airboats. I can’t wait!
I purchased a older 15x7’ 30” deep aluminum boat with a smooth running mild 350 Direct Drive 72” whirlwind 2 blade. Soon to install 3/8 poly.
I’m selling the prop and 350 motor.
I purchased a low hour complete 5.3 with Dbw gas pedal, harness ect.
This should get me a lot more power, reliability, and a little weight savings over the 350.
I want to learn how to drive it pretty good before getting into more HP. Eventually I will build a 6.0 or a BBC.
Looking to build a fairly capable hunting fishing boat.
I want to use the 5.3 factory stuff as much as I can to keep the cost down and keep it reliable.
Any recommendations for the harness work and tune?
Any other parts to consider?
I have all the parts below except the
prop, cam+springs, and Exhaust.
I will be building the engine. I have built engines before.
Not airboat specific engines though.
I gathered these parts from reading here and all over.
Reliable and as quiet as possible is the goal.
PARTS TO BE INSTALLED:
78”-80” 3blade ($1700 used stump puller)
prop or similar? No larger.
Quiet Exhaust system?
Texas speed stage 2 low lift cam with springs and seals?
Rotator 2.37 gearbox
Trunion upgrade
Hardened push rods
Ls7 lifters and trays
Flat top pistons and rod bearings
High volume oil pump
Oil pickup tube brace
Billet oil diverter barbell
Thanks for the help!
