Default Prop Upgrade for Reg 23 w/ Twin 150s?

Hey, all. Has anyone upgraded to four blade or other props on their 23 with twin 150s? If so, what prop did you go with and what performance/economy improvements have you experienced?

I have a 2005 23 with twin 150's and had 3-blade 18 pitch props. Fuel economy was about 2.1 around 3800 rpms and roughly 26-28 mph. I added 4-blade Powertech 16p props and the ride and handling was greatly increased. Less tab used, less porpoising, and boat just overall rode better in our short wave duration on Lk. Erie. I have not nailed down the performance numbers yet but it appears to have lost a couple mph, which I expected. But I will take the loss of speed with what I gained in ride and handling.

I haven't really done a REAL test for any distance and with trimming up the motors. Right at 5600-5700 is the ballpark where I am at. With the 18p, I was about 5400-5500. I feel that I am better propped now and the motors just seem to run with less strain and more freely.

At those rpms are you not concerned that your lugging those motors?

NO...like I said...I did not do a real test playing with trim and was not a light load and motors were buried. With the 16p 4-blade they sound so much better than the factory 18p 3-blade. Definitely lugging a lot less than a factory setup. I've been told and have heard that Yamaha wants you in the 5000 to 6000 rpm range with closer to 6000 the better. Me...I was 5700 with not the lightest load and little to no trim on the motors...I think I am good!

I went with Mercury Enertia 14.5x17p. I also raised my motors one hole. I cruise at 4100-4200 @31 mph 2.1 mpg. Half tank of fuel with 3 adults. Top end is 5800 at 47-48 mph. Offshore load full fuel and gear and ice. 4100 at 27-28 1.8. Very happy with performance of these props. Been thinking about going up one more hole just to try just havenít gotten to it.
