Vector/Merc 150 Setup

Dear Randy:  

I bought a Vector 1979 with a Mercury 2.4 Bridgeport 1986. The engine was giving me a lot of headaches so I decided to change to a Mercury 150 EFI. I decided that this beautiful boat deserved the best and now has new paint, hydraulic steering, jack plate. What kind of prop do I need for this boat for ski and speed. Where should I place the shaft on the transom.

Thank you

The Vector/150 package is a very good one. Great OVERALL performance. We've set up in the past about a half dozen or so. The following set up recommendation is very easy and works within a couple of mph of the "jack plate and highrise" set up combos out there. We tried the high on the transom route and the results were far from satisfactory. We wanted great holeshot, good top end (and repeatable at that), weight carrying ability, and the least amount of gaudy brackets and such. We mounted the motor about 2 1/2 inches up on the transom with no jack plate. We ran a small (14") diameter Merc chopper, 26" pitch. This package ran 77mph with about any load in the boat. Without a plate the low speed porpoise that Vectors have was not near as pronounced as with a plate. Since those props are hard to find a 26 Yamaha drag prop would work. A 25 or 26 Trophy small hub will be good too. The best prop is the last I'll talk about, the 26" SMALL HUB Laser 2 Merc three blade. This prop will run big numbers on the top and punch better than a drag prop. We put one on an Allison Grand Sport and 200 ProMax this summer. The boat ran 85 MPH and pulls slalom skiers like they weren't there. 

Try that prop and you'll be hooked.
