Hi everyone,
We just picked up our SA550 and hitting the lake tomorrow.

I’ve done a lot of reading and searching since last fall but still confused on the 1.5 gear ratio that we have in the SA550 and prop selection.

We ordered the boat with the 16x13.9 prop so it’s going to pull like crazy.

Why does the 550 have a 1.5 ratio vs the 1.76 in the 400/450?

Should we have gotten the 16x15 prop or should I get that prop as my back up/spare?

I understand the impacts of diameter and pitch but for the life of me can’t figure the impact from the gear ratio.

Thanks in advance for some education.
