mercruiser alpha gearing for 23 tsunami

[hedgehog]

Thanks for the input....I was trying to do the math in my head and was assuming, maybe incorrectly, that the 1.65 ratio would give me a little more low end which is much needed for the weight of the boat.

I am running a 15x17 alum prop which seems to perform well...just keeps me a few hundred rpm shy of max wot. I am more interested in overall performance rather than speed so looks like I will stay with the same dia/pitch this season.

Thank you both for your reassurance and input
