Prop Testing

[mamboking]

I am looking to try some different propellers on my boat;

Currently running a Bravo 1 24p four blade, boat not pulling enough revs.

Does anyone have anything lower pitched i can borrow next weekend (Sep 6th) for some testing; running out of Drivers. Willing to purchase anything that works, if for sale that is.

We did loads of testing with your particular boat, and the very best prop was a Mach 24" 4 blade Sterndriver. Not easy to find anymore, as the company went to the wall ages ago.

I think I may be able to put my hand on one though!

Hi Tony the boat came with a Mach Sterndriver 24P which i changed for the Bravo 1, 2 seasons ago. The boat is not quite on song so last time out i switched back to the Mach and cant pull any more than 4200rpm, similar results to the Bravo 1.

Very different handling with the Mach though, much more positive trim needed.

Any ideas if not the prop?

Yeh, your motor's been rogered

He swears blind its not the motor; the boat has never reved much higher, whats the rev range of a Magnum?

Full Throttle RPM Range: 4600-5000 for a 454 mag mpi

Cheers, mine is the older twin carb set up not sure if this changes the rev range, looked around on the net and there are so many different opinions.
