Ok, recently I purchased a boat that came with a bravo outdrive on it. My question to you guys is this, will an Alpha one prop fit on a Bravo drive?:joyous:

Hi ericcarr, I am in the process of re power the 90 Sea Ray Sundancer powered with 7.4L bravo 1 combo like in your signature, see my progress in mine. Just curious what prop you are planning to run and what #s you come up with. My boat was a free sandy victim so I know little about how she performs. I do have the original (NG) drive that had I think a 17 pitch aluminum prop on it. My boat is a long way from the water.

Well I took her out for a quick drive this past weekend and ran a 45 MPH with a 17 pitch prop.

And now for the rest of the story. What rpm were you getting at 45 mph?

In order to evaluate performance, it requires gear ratio, pitch, rpm, and speed.

I didn't really look at the RPM's, besides, jestor All I really was asking is if an alpha one prop fit onto a bravo unit. Nothing was ever mentioned about performance as of yet.

My apologies sir!

My assumption that you might be interested in actually diagnosing performance was in error.

By the by; your statement that your boat does a certain speed using a certain pitch prop is borderline meaningless, since the Bravo drive is available in three different gear ratios, and a 17 pitch prop is available in different diameters and materials and designs.

Unless you specify what you're talking about, it doesn't mean much; meaning his boat won't necessarily do the same.

Well when he asked me what prop I plan on running and what my numbers were, All I really did was tell him what I ran with what size prop.:facepalm:
