Hi Guys,

New to the forum.
I got an un tested and unknown 42 1999 fountain lightning. I got it not running. it has staggered 502 cube 500 carb mercruisers that have B & M 250 blower on top. have just fitted two new Bravo XR drives 1.5 ratio and because of the different sized output shaft i need to put new props on it. The old ones were hydromotive 4 blade 29s, as mentioned before, i have no idea how it ran before with these. Whats the general consensus? Do you thnk the 29;s are a good starting point??

Thanks
Christian

I would try a set of 30 or 32 Bravo's as a starting point, you should be at least 650hp with that set up

Wow at least 650 you think??? It has low compression pistons and cam to suit the blower roller lifters roller rockers and 1050 dominator. I was thinking more around 575 - 600hp.
You say bravos rather than hydromotives??
thanks

I had a 99 42 Lightning with 600 Innovations a few years ago. I found that the Hydromotive P5X 5 blades worked best, I think they were 29's but not 100% sure. The P5X carried the bow nicely.
Good luck......
