Zodiac f470 roll up floor

[Romeo34]

Hi all!

Awesome site. There's definitely a wealth of experience and knowledge here.

I recently bought two zodiac f470 from the auctions and they came with roll up floors and aluminum floors (no stringers though, so frustrating). Anyways I have a 50hp motor ready to put on one of them but the user manual says 40hp is the max rating when using the roll up floor. So basically I'm looking for some guidance on wether I should use the slightly overpowered donk or not. I've seen videos on YouTube of people with 50's and roll up floors and they seem fine. Also the f470's we use at work are fitted for two 25hp motors on the transom which are then loaded up exceeding max payloads and abused over long distance transits hold up fine as well. So yeah people thoughts on the matter are welcomed. Also an stringer alternative for the aluminum floors would be welcome to.

Cheers blokes.

Take off the decal and u will be fine with the 50.
Maintain spec MBT (Main Buoyancy Tube and LBT (Lower Buoyancy Tube)air presure.
Do u have the transom straps? Tig weld up some stringers from a Grand Raid into one piece per side. These show up here at boat salvage scapers on rare occasions.

Cheers

Ah good to hear. Yeah I have the transom straps. MBT and speed skegs pressure should be 3.5 psi right? As I said the ones we use at work never adhere to the writing in the manual and they're still serviceable. As for the stringers I'm down here in Australia so I'd probably have trouble buying off the forum seeing as its mostly US / UK? That being said are all zodiac stringers across all models the same and its just there length that varies? If that's the case I could just weld up the correct lengths.

Next question. Can I tow a tube or water skier with this setup? I feel like the engine should be able to cope. It's been extensively modded for racing as it came off a thundercat inflatable.

If the boat is not properly inflated it will flex front to back a bit.

Exceeding the weight capacity will hook the hull too.
