Simple SportJet Question, I hope
I swapping 175 SporJet pumps on my Searayder F16. My pump had a hard life before I got it. I found a second boat with 50 hours on it and a blown power head. I question is the second pump has 1.50 engraved in the end of the input shaft of the pump. Does anyone have any idea what that could mean? Could this have a different gear ratio? over size bearings? was it a pump for a 120 hp at one time? I have no info from the original owners.

I was wrong on the number, Its 1.25 engraved into the end of the input shaft. the other pump has nothing on it. On Sunday its going in. I guess if its wrong, I'll find out the hard way.
