Gotcha

I love the boat so far even though it's given me quite a few issues. Once i get them worked out i should be good for a while. Motor is rebuilt and cammed with less than 300 hrs on it and now the whole outdrive is rebuilt.

I guess the biggest question about this is which engine is it? The hp500efi or a 502mpi? There is some difference there. Either way I'd say it should be low 60s wirh a 23 mirage plus even if it's the 435hp black 502.

It's the blue 502mpi

If it's a 500 hp engine I would think closer to 70. What size prop? I was getting 64 out of a 425hp 454 with a 23 mirage plus turning it 5400rpm. Seems to be par for the course amongst others.

23p Mirage+. Specs on the motor say max rpm is 4800 though? And that's what it turns trimmed up. I can only get 55 mph on the boat

The stock 330 with 23 mirage plus was 54 mph. Maybe you have a black motor someone painted blue when they overhauled it?

check power steering hoses for oil leakage.

Alright thanks
