I have both types of speedo. I brought my handheld garmin with me to check speed.

I dont know what gear ratio I have. Do you think 1.5 is probably what I have?

My tach may be off. I have only owned the boat a month and its now in the shop. My season is over , the transom assembly blew up.

I appreciate your input. This is the first fast boat I have owned. 40mph used to be fast on my 4 winns:rolleyes:

the only thing I am sure of is the speed. Plus I only hit 64 for a shotr time in chop. 62 easy.
