Currently been working on a 33AVS project. It’s time to buy power. I originally wanted to build 540’s but with the money that’s already been spent that might have to be down the road. I came across a pair of low hours 496HO’s. Wondering what the performance will be with this power and whats the best props to run? TIA

28b1’s and 74-75

496 HO's, not HO Mag? Kind of like a Vette with a 4 banger in it.

good catch. My numbers were for mags.

do you know the performance with 496 HO’s 425hp. Not the 375hp mag motors.

Back to the numbers above then. Friend had a 33 with 415hp 502 mag mpi’s. Right at 74 on radar.

My 33 avs 496 HO has seen 82mp/h (gps) on top with basically no fuel/cargo and good chop, it will however run 77-78 anyday of the week no matter the weight, has stock bravo xr drives with stock bravo1 30p props spinning in, freshwater, quite pleased with those numbers!

Your turning stock bravo one 30s with 496 hos? how many rpms? Thats pretty impressive. on my 33 w butchered up 28s I saw 77/78 w 500 efis on rev limiter, with labbed 30s I saw 85, with box stock 30s I saw 81/82 ish under best conditions and it struggled to pull past 79/80 mph with them with 500s, Smitty

Rpm is right around 4900, my boat is lighter than standard due to a carbon fibre engine hatch (no sunpad), that saves me around 200 lb, perhaps that's the key to my speed, speed is verified with several different gps;s though.
Entire hatch is 30 lb with gas pistons and latches and you can walk on it no problem!

Scarabeman,

Don't believe there is such a beast as a "496HO (non MAG)". I believe it's either a "496MAG" or a "496MAG HO". The HO is higher output than the MAG.

Thanks. Brad.
